Hereditary sensory and autonomic neuropathy type 1c is a rare inherited nerve disorder that usually begins in adolescence or adulthood. People with hereditary sensory and autonomic neuropathy type 1c often lose feeling in the feet and hands, and this can lead to burns, sores, infections, and trouble with balance. Early symptoms of hereditary sensory and autonomic neuropathy type 1c may be easy to miss because numbness and foot problems can build slowly over many years. Not everyone will have the same experience, but the condition is usually lifelong and can become more disabling over time. Treatment for hereditary sensory and autonomic neuropathy type 1c focuses on protecting the skin and feet, treating pain and infections, and using supportive care, while life expectancy depends on severity and complications.
How many people live with Hereditary sensory and autonomic neuropathy type 1c?
There is no reliable published estimate of how many people worldwide or in the United States live with hereditary sensory and autonomic neuropathy type 1c. This form is considered extremely rare, but major medical reference sources do not provide a regular global or U.S. count for it.
Overview
Hereditary sensory and autonomic neuropathy type 1cSymptoms
Hereditary sensory and autonomic neuropathy type 1c often causes slowly worsening numbness, burning pain, and loss of feeling in the feet and hands. Some also develop weakness, foot ulcers, or trouble with sweating, blood pressure, or digestion.
Outlook and prognosis
Hereditary sensory and autonomic neuropathy type 1c usually progresses slowly over years. Many living with this condition can stay active, but numbness, foot ulcers, infections, weakness, and balance problems may gradually make walking and daily tasks harder.
Causes and risk factors
Hereditary sensory and autonomic neuropathy type 1c is caused by a change in the SPTLC2 gene. It is usually inherited from one affected parent, though a new gene change can happen. Foot injuries, pressure, and diabetes can worsen complications.
Genetic influences
Genetics are central to hereditary sensory and autonomic neuropathy type 1c, because it is caused by an inherited gene change. Different genetic variations can affect when symptoms begin, how severe they are, and which family members are affected.
Diagnosis
Hereditary sensory and autonomic neuropathy type 1c is usually diagnosed from clinical features such as reduced pain sensation, nerve damage, and family history. The genetic diagnosis of hereditary sensory and autonomic neuropathy type 1c is confirmed with genetic tests, and sometimes nerve studies.
Treatment and drugs
Treatment for hereditary sensory and autonomic neuropathy type 1c focuses on protecting numb feet and hands, treating wounds early, and easing nerve pain. Many living with hereditary sensory and autonomic neuropathy type 1c also benefit from regular foot care, supportive shoes, and physical therapy.
Symptoms
A small cut from a tight shoe or a burn from bath water may go unnoticed, especially in the feet. In hereditary sensory and autonomic neuropathy type 1c, this happens because the nerves that carry pain, temperature, and some automatic body signals do not work as they should. Features can vary from person to person and can change over time. The early features of hereditary sensory and autonomic neuropathy type 1c often involve numbness, burning nerve pain, or slow-healing sores on the feet.
Pain, heat, and cold may be harder to sense, usually starting in the feet and lower legs. Because of this, people with hereditary sensory and autonomic neuropathy type 1c may not notice blisters, cuts, or pressure from shoes until the skin is already damaged. In some people, similar loss of feeling also develops in the hands.
Even with numbness, some people also have burning, stabbing, or electric shock-like nerve pain. This can be worse at night or after time on their feet and may make sleep or walking harder.
Small injuries can turn into open sores, especially on the toes, soles, or other pressure points. These wounds may heal slowly because repeated rubbing or unnoticed trauma keeps irritating the area.
When sores are not felt early, skin and deeper tissues can become infected. In more severe cases, repeated infections can damage soft tissue or bone and raise the risk of losing a toe or part of the foot.
How people usually first notice Hereditary sensory and autonomic neuropathy type 1c?
Many people first notice hereditary sensory and autonomic neuropathy type 1c when pain or temperature stops feeling normal in their feet, so a blister, cut, or burn may go unnoticed until it is already there. As the condition progresses, people with hereditary sensory and autonomic neuropathy type 1c may develop numbness, tingling, burning pain, or weakness that slowly climbs from the feet into the lower legs, and some also notice balance problems or foot ulcers that heal poorly. Because these changes usually build gradually rather than all at once, the first signs of hereditary sensory and autonomic neuropathy type 1c are often mistaken for a more common nerve problem until repeated injuries or worsening sensation loss prompt a closer look.
Types of Hereditary sensory and autonomic neuropathy type 1c
No distinct types or clinical variants of hereditary sensory and autonomic neuropathy type 1c are widely recognized.
Can I slow down the onset of symptoms?
No, at this time there is no good proof that lifestyle changes or standard treatment can reliably delay when symptoms begin in hereditary sensory and autonomic neuropathy type 1c, because this is a rare inherited nerve condition mostly driven by the gene change itself. Healthy habits such as not smoking, limiting alcohol, protecting your feet, and treating other problems that can harm nerves, like diabetes, may help reduce extra nerve damage and lower the risk of complications, but they have not been shown to prevent the condition or clearly push back its start. Research on more targeted treatments is ongoing, so regular follow-up with a nerve specialist and early care for numbness, pain, or foot injuries can still help you stay as well as possible.
What genetics can tell you about symptoms
Genetics can give some clues about symptoms in hereditary sensory and autonomic neuropathy type 1C, but it usually cannot predict the exact course for any one person. In general, the disease-causing genetic change affects the nerves that carry pain, temperature, and automatic body signals, which helps explain why many people develop numbness, reduced ability to feel injuries, foot ulcers, or weakness, but the age symptoms start and how severe they become can vary even within the same family. This means genetic testing can help confirm the diagnosis and sometimes suggest the overall pattern of symptoms, yet it does not fully forecast which problems will show up first or how quickly they will progress.
Causes and risk factors
Hereditary sensory and autonomic neuropathy type 1c is caused by a change in the SPTLC2 gene, and this change is usually inherited from a parent. If one parent has this gene change, each child has a 1 in 2, or 50%, chance of inheriting it. Family history is the main risk factor for hereditary sensory and autonomic neuropathy type 1c, although some people develop it from a new gene change that was not inherited. On top of genetics, everyday habits also matter. Smoking, heavy alcohol use, diabetes, and other causes of nerve injury do not cause hereditary sensory and autonomic neuropathy type 1c, but they may make nerve damage and symptoms worse.
What are the most common causes or risk factors?
Hereditary sensory and autonomic neuropathy type 1C is mainly caused by an inherited change in a gene called SPTLC2, which helps keep nerves healthy. The biggest risk factor is having a parent or close family member with this condition, although in some people the gene change can happen for the first time in the family. There are no well-established lifestyle or environmental causes, and symptoms often do not show up until adulthood.
Environmental and biological risk factors
For hereditary sensory and autonomic neuropathy type 1c, experts have not identified any confirmed environmental or non-genetic biological risk factors that increase the chance of the condition occurring. Some biological risks are written in our genes, others arise through environment, but this condition has not been linked in a reliable way to maternal illness, infections, pollution, radiation, or other outside exposures. If you are looking into the causes of hereditary sensory and autonomic neuropathy type 1c, current evidence does not support a separate list of preventable environmental or body-based risks.
Genetic risk factors
When people look into the genetic causes of hereditary sensory and autonomic neuropathy type 1c, one gene stands out. Hereditary sensory and autonomic neuropathy type 1c is mainly linked to harmful changes in SPTLC2, a gene that helps nerves make certain fats they need to function. It usually runs in families in an autosomal dominant pattern, so one altered copy can be enough to cause the condition. Risk is not destiny—it varies widely between individuals.
SPTLC2 changes: The main known cause is a harmful change in the SPTLC2 gene. This change can disturb the balance of fats important for nerve health and lead to gradual nerve damage.
Autosomal dominant: Hereditary sensory and autonomic neuropathy type 1c is usually passed down in an autosomal dominant pattern. This means a child has a 50% chance of inheriting the altered gene if one parent carries it.
Family history: Having a parent or other close relatives with hereditary sensory and autonomic neuropathy type 1c is the clearest inherited risk factor. Families often notice the condition across several generations, although the age symptoms begin and how severe they become can vary.
Variable expression: Even within the same family, the same SPTLC2 change can affect people differently. Some may develop problems earlier or have more severe nerve symptoms than relatives who carry the same genetic change.
Lifestyle risk factors
Hereditary sensory and autonomic neuropathy type 1C is inherited, so lifestyle habits do not cause it. However, how lifestyle affects hereditary sensory and autonomic neuropathy type 1C can be important because daily habits may change the risk of ulcers, injuries, infections, pain flares, and loss of function. The most relevant lifestyle risk factors are the ones that increase unnoticed trauma, delay wound care, or worsen overall nerve stress. Practical prevention habits can make a meaningful difference in day-to-day complications.
Skipping daily skin checks and routine foot care can allow blisters, cuts, or pressure sores to go unnoticed because sensation is reduced. Careful inspection, nail care, and early treatment of small wounds may lower the risk of ulcers and infection.
Tight shoes, rough seams, barefoot walking, or repeated friction can increase skin breakdown in areas that a person may not feel normally. Protective, well-fitted footwear and cushioned socks may reduce trauma and pressure injuries.
High-impact exercise, repetitive pounding, or long periods of walking without breaks can raise the risk of stress injuries, calluses, and joint damage. Lower-impact activity with pacing may help preserve mobility while limiting unnoticed tissue injury.
Very hot bathwater, heating pads, hot pavement, or warming devices can cause burns when temperature sensation is impaired. Using temperature checks and avoiding direct heat exposure can reduce preventable skin injury.
Risk prevention
Hereditary sensory and autonomic neuropathy type 1c is an inherited nerve condition, so there is no proven way to prevent the condition itself from occurring. Prevention usually means lowering the risk of injuries, infections, ulcers, and worsening nerve problems over time. Prevention is flexible—it adapts to your life and health background. For many living with hereditary sensory and autonomic neuropathy type 1c, this can mean building daily habits that protect feet, skin, and overall health even when pain signals are reduced.
Reduced pain sensation can make cuts, blisters, or pressure spots easy to miss in hereditary sensory and autonomic neuropathy type 1c. Checking your feet every day, including between the toes, can help catch early symptoms of hereditary sensory and autonomic neuropathy type 1c such as skin breakdown or unnoticed injury before they become serious.
Well-fitting shoes, cushioned socks, and avoiding walking barefoot can lower the chance of burns, punctures, and pressure injuries. Many people with hereditary sensory and autonomic neuropathy type 1c benefit from podiatry advice or custom insoles if foot shape or pressure points are a problem.
Dry skin, cracks, and small wounds should be cleaned and treated early because healing problems can raise the risk of infection. Prompt care matters especially if an area becomes red, swollen, warm, or starts draining fluid.
Some may not feel heat normally, so hot bath water, heating pads, space heaters, and very hot pavement can cause injuries without much warning. Testing water temperature first and using extra caution around heat sources can help prevent burns.
Can you prevent Hereditary sensory and autonomic neuropathy type 1c?
No, you cannot fully prevent hereditary sensory and autonomic neuropathy type 1c because it is an inherited nerve condition caused by a gene change present from birth. What you can do is lower the chance of some complications by protecting the feet and hands from injuries and burns, checking the skin often, and getting early treatment for sores or infections. If this condition runs in your family, meeting with a genetics specialist may help you understand the chance of passing it on, but it cannot stop the condition in someone who has inherited it.
Transmission
Hereditary sensory and autonomic neuropathy type 1c is not infectious, so it cannot spread from person to person through everyday contact, kissing, sex, food, or blood. Instead, how Hereditary sensory and autonomic neuropathy type 1c is inherited matters most.
This condition usually follows an autosomal dominant inheritance pattern, which means one altered copy of the gene is enough to cause it. For many families, that means a parent living with Hereditary sensory and autonomic neuropathy type 1c has a 1 in 2, or 50%, chance of passing it to each child. In some cases, the gene change starts for the first time in one family member, but after that it can be passed on to future children.
When to test your genes
Consider genetic testing if you have a family history of hereditary sensory and autonomic neuropathy, or if numbness, reduced pain sensation, foot ulcers, or unexplained nerve pain begin early or run in the family. Testing can confirm the diagnosis, guide monitoring, and help relatives understand their own risk.
Diagnosis
Hereditary sensory and autonomic neuropathy type 1c is usually diagnosed when a pattern starts to emerge over time, such as reduced feeling in the feet, repeated injuries that go unnoticed, or problems with sweating and blood pressure. Because this is a rare inherited nerve disorder, doctors often combine the exam, family history, and specialized nerve testing rather than relying on one clue alone. It’s natural to worry when symptoms don’t have a clear explanation, but the diagnosis of hereditary sensory and autonomic neuropathy type 1c is meant to sort out other, more common causes first and then confirm the condition more precisely.
Doctors ask about numbness, burning pain, foot wounds, balance problems, and symptoms linked to automatic body functions such as sweating changes or dizziness on standing. A detailed family and health history can help show whether similar nerve problems have affected relatives across generations.
The exam checks feeling in the feet and hands, muscle strength, reflexes, and balance. Doctors also look for injuries, ulcers, or foot shape changes that can happen when pain and temperature sensation are reduced.
Nerve conduction studies and electromyography, often called EMG, help show how well the peripheral nerves and muscles are working. In hereditary sensory and autonomic neuropathy type 1c, these tests can support the diagnosis and help rule out other neuropathies.
Doctors may perform tests that look at heart rate, blood pressure, and sweating to see whether the autonomic nerves are affected. These findings can help explain day-to-day symptoms like lightheadedness, heat intolerance, or unusual dry skin.
How is Hereditary sensory and autonomic neuropathy type 1c diagnosed?
Doctors usually diagnose hereditary sensory and autonomic neuropathy type 1c by putting together a person’s symptoms, family history, and an exam that checks feeling, reflexes, strength, and problems such as painless sores in the feet or hands. They often use nerve tests that measure how well signals travel through the nerves, and sometimes tests of sweating or other automatic body functions, while also ruling out more common causes of nerve damage such as diabetes. A genetic test can then help confirm the diagnosis by looking for a harmful change in the SPTLC2 gene.
Stages of Hereditary sensory and autonomic neuropathy type 1c
Hereditary sensory and autonomic neuropathy type 1c does not have defined progression stages. This is because it usually develops gradually and can vary a lot from one person to another, rather than moving through a clear set of fixed steps. Often the process begins when you notice changes in daily life, such as numb feet, repeated unnoticed injuries, burning pain, or balance problems, and doctors then look at symptoms, the nerve exam, and family history. Diagnosis and follow-up may also include nerve tests and genetic testing, especially when the early symptoms of hereditary sensory and autonomic neuropathy type 1c overlap with other inherited nerve conditions.
Outlook and prognosis
The outlook for hereditary sensory and autonomic neuropathy type 1c is variable but is often slowly progressive over many years, with symptoms typically worsening from sensory loss and neuropathic pain to foot ulcers, infections, balance problems, and sometimes weakness. Many affected people have a near-normal life expectancy, especially with early foot care, pain management, physical therapy, and prompt treatment of wounds. Prognosis is driven less by rapid neurologic decline than by preventable complications such as repeated injuries, osteomyelitis, and amputations, which can significantly affect mobility and quality of life. Autonomic symptoms are usually not the main determinant of outcome in this subtype, but they can add to disability in some individuals. Death is not considered a usual direct feature of hereditary sensory and autonomic neuropathy type 1c, though severe wound infections and related complications can rarely become life-threatening. Genetic counseling and long-term multidisciplinary care can improve function and help reduce complications over time.
Long-term effects
For many living with hereditary sensory and autonomic neuropathy type 1c, the main long-term effects come from gradual nerve damage in the feet and hands, which can change how safely and comfortably daily life feels. Long-term effects vary widely, and some people have a slower course while others develop more noticeable problems over time. Many find that walking, checking for injuries, or handling heat and cold can need extra caution as the years go on.
Loss of pain, temperature, and touch sensation often starts in the feet and may later affect the hands. This can make a blister, cut, burn, or tight shoe easy to miss until the skin is already damaged.
Repeated pressure and unnoticed injuries can lead to open sores, especially on the soles or toes. These wounds may heal slowly and can come back, even when the early symptoms of hereditary sensory and autonomic neuropathy type 1c seemed mild.
Skin breakdown can let bacteria enter deeper tissues and raise the risk of serious infections. In some people, infection can spread to bone and become a long-term source of pain, swelling, or disability.
Walking on an injured foot without normal warning pain can gradually damage bones and joints. Over time, this may lead to deformity, instability, or changes that make standing and walking harder.
How is it to live with Hereditary sensory and autonomic neuropathy type 1c?
Living with hereditary sensory and autonomic neuropathy type 1C often means having reduced feeling in the feet and sometimes the hands, so everyday problems like a blister, burn, or cut may go unnoticed until they become a sore or infection. For many people, this can make daily life revolve around foot checks, careful footwear, skin care, and extra caution with heat, long walks, or any activity that could cause hidden injury; some also develop weakness or balance problems that make moving around more tiring. The condition can affect the people around you too, because family members may help with wound care, appointments, and home safety, but with steady monitoring and practical routines, many living with HSAN1C are able to protect their health and stay engaged in daily life.
Treatment and drugs
Treatment for hereditary sensory and autonomic neuropathy type 1c focuses on managing symptoms, protecting the hands and feet, and preventing complications, because there is no cure that reverses the underlying nerve damage. Many living with hereditary sensory and autonomic neuropathy type 1c need regular foot care, well-fitting shoes, and quick treatment of cuts, burns, pressure sores, or infections, since reduced pain sensation can make everyday injuries easy to miss. Doctors may use medicines for nerve pain, along with physical or occupational therapy, braces or custom inserts, and help with balance or weakness if walking becomes harder. Treatment plans often combine several approaches. Because this condition is inherited and can vary from one family member to another, follow-up with a neurologist and genetic counseling can also be an important part of care.
Can you cure Hereditary sensory and autonomic neuropathy type 1c?
No, there is no cure right now for hereditary sensory and autonomic neuropathy type 1c. Treatment focuses on managing problems caused by the condition, such as pain, numbness, injuries you may not feel, and body functions that happen automatically, like sweating or blood pressure changes. For many people, this means regular checkups, careful skin and foot care, pain treatment, and support to help them stay as safe and active as possible.
Non-drug treatment
Living with hereditary sensory and autonomic neuropathy type 1c often means paying close attention to injuries, balance, and day-to-day body signals that may be easy to miss. Managing this condition often centers on preventing foot damage, staying mobile, and catching skin or joint problems early. Even when early symptoms of hereditary sensory and autonomic neuropathy type 1c are mild, daily habits and supportive therapies can help protect function and comfort. Because symptoms vary, care is usually tailored to the areas most affected.
Daily foot checks and careful nail and skin care help because cuts, blisters, or pressure sores may not hurt as a warning sign. Well-fitting shoes, soft socks, and pressure-relieving insoles can lower the risk of ulcers and infection.
Protecting the skin from burns, friction, and repeated pressure is a key part of treatment. Some non-drug options are delivered by specialists, including podiatry care, custom footwear, and wound care for slow-healing sores.
Physical therapy can help maintain strength, balance, and joint movement, which may make walking safer and less tiring. For many, treatment begins not at the pharmacy, but with guided exercises, stretching, and gait training.
Occupational therapy helps with hand use, daily tasks, and home safety when numbness or weakness gets in the way. Splints, adaptive tools, and small changes at home can make cooking, dressing, or bathing easier and safer.
Your genes may have an impact on how drugs work for you
For people living with hereditary sensory and autonomic neuropathy type 1c, medicines are usually used to ease problems like nerve pain, skin wounds, or infections rather than to treat the root cause, and there is no well-established evidence that this condition’s genetic change clearly predicts which of these common medicines will work best. Even so, inherited differences can affect how some people process pain medicines or other drugs in general, so one person may get good relief while another feels little benefit or has more side effects. In day-to-day care, this usually means treatment is adjusted by watching symptoms closely and changing the dose or medicine if needed, rather than using a special gene-based drug test for this condition.
Pharmacological treatments
Daily life with hereditary sensory and autonomic neuropathy type 1c often centers on nerve pain, foot sores, and infections rather than a single medicine that changes the condition itself. Drug treatments aren’t about fixing everything at once, but easing symptoms and helping prevent complications. In practice, treatment for hereditary sensory and autonomic neuropathy type 1c is usually individualized, because pain, numbness, and autonomic symptoms can vary a lot from one person to another. There is currently no widely approved disease-modifying drug specifically for this condition.
Gabapentin and pregabalin are commonly used for burning, shooting, or electric-like nerve pain. They do not repair damaged nerves, but they can make day-to-day pain more manageable. Dosing may be increased or lowered gradually to limit sleepiness, dizziness, or swelling.
Duloxetine and the tricyclic antidepressants amitriptyline or nortriptyline are also used for neuropathic pain. Many living with hereditary sensory and autonomic neuropathy type 1c may notice better sleep or less constant pain when one of these works well. Dry mouth, constipation, and drowsiness can matter, especially if autonomic symptoms are already present.
Lidocaine patches or capsaicin cream may help with smaller areas of nerve pain or tenderness. These options act locally, so they may cause fewer whole-body side effects than pills. Some people may find them useful when shoes, socks, or bed sheets make the skin feel painfully sensitive.
Antibiotics are used when numb feet or hands develop infected ulcers, skin breakdown, or deeper soft-tissue infection. The exact drug depends on the likely bacteria and how serious the infection is. Never stop or change a prescription without checking with your healthcare provider.
Genetic influences
For many living with hereditary sensory and autonomic neuropathy type 1c, the pattern often becomes clear when numbness, pain, or unnoticed foot injuries have affected several relatives across generations. In this subtype, the genetic cause is established: it is usually caused by a change in the SPTLC2 gene. This gene helps make fats that nerve cells need, and the condition is most often inherited in an autosomal dominant way, meaning one changed copy from either parent can cause it and each child has a 50% chance of inheriting it. Family history is one of the strongest clues to a genetic influence. Even within the same family, symptoms can begin at different ages and vary in severity, so one relative may have milder sensory loss while another has more noticeable nerve pain or weakness. If you are wondering whether hereditary sensory and autonomic neuropathy type 1c is inherited, the answer is yes, and genetic testing can help clarify the risk for close relatives.
Is Hereditary sensory and autonomic neuropathy type 1c genetic?
Genetics are central to hereditary sensory and autonomic neuropathy type 1c, because it is caused by an inherited gene change. Different genetic variations can affect when symptoms begin, how severe they are, and which family members are affected.
Having a genetic risk is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are widely seen in the general population. Most do not have a direct impact on health and simply reflect natural differences among people. In many genes, having a variant associated with a condition points to a possible link rather than a firm diagnosis, especially when several genes and environmental factors play a part. In some situations, though, a single well-characterized variant in a specific gene is enough to confirm the diagnosis.
Pharmacogenetics—how genetics influence drug effects
For many living with hereditary sensory and autonomic neuropathy type 1c, treatment is less about finding one perfect drug and more about matching care to the exact gene change and the symptoms that affect daily life. In hereditary sensory and autonomic neuropathy type 1c, the altered gene disrupts how the body makes certain fats that nerves need, so genetic testing can confirm the diagnosis and help specialists decide whether standard supportive care is the main approach and whether a research study may be appropriate. There are no widely used pharmacogenetic rules that can reliably tell doctors which pain medicine or other symptom treatment will work best for every person with this condition. Not every difference in response is genetic, but age, liver and kidney function, other medicines, and how advanced the nerve damage is can all change how well a treatment works and how likely side effects are. In practice, the best treatment for hereditary sensory and autonomic neuropathy type 1c usually combines genetic results with careful symptom tracking, dose adjustments, and practical steps such as protecting numb feet and hands from injury.
Interactions with other conditions
For many living with hereditary sensory and autonomic neuropathy type 1c, the biggest day-to-day issue is not just numbness or pain, but what those nerve problems can lead to over time. Because feeling in the feet or hands may be reduced, minor cuts, pressure sores, or burns can go unnoticed and may become skin infections, deeper soft-tissue infections, or sometimes bone infection if they are not treated early. Problems with sweating and blood flow can also make skin breakdown more likely, especially in people who already have poor wound healing.
Another important aspect is how it may link with other diseases. Diabetes, circulation problems, and foot deformities can make the symptoms of hereditary sensory and autonomic neuropathy type 1c harder to manage, since each of these can raise the risk of ulcers, infection, and slow healing. Some may also develop joint damage from repeated unnoticed injury, and this can overlap with arthritis or mobility problems in a way that makes walking and balance more difficult. If you are wondering about the early symptoms of hereditary sensory and autonomic neuropathy type 1c, it is worth telling your doctor about repeated injuries, unexplained wounds, dizziness, or temperature-sensing problems, especially if another condition could be adding to them.
How genes can cause diseases
Humans have more than 20,000 genes, each carrying out one or a few specific functions in the body. One gene instructs the body to digest lactose from milk, another tells the body how to build strong bones and another prevents the body's cells from beginning to multiply uncontrollably and developing into cancer. As all of these genes combined are the building instructions for our body, a defect in one of these genes can have severe health consequences.
Through decades of genetic research, we know the genetic code of any healthy/functional human gene. We have also identified that in certain positions on a gene, some individuals may have a different genetic letter from the one you have. We call these hotspots "Genetic Variations" or "Variants" in short. In many cases, studies have been able to show that having the genetic letter "G" in the position makes you healthy, but having the letter "A" in the same position disrupts the gene function and causes a disease. Genopedia allows you to view these variants in genes and summarizes all that we know from scientific research, which genetic letters (Genotype) have good or bad consequences on your health or on your traits.
What other conditions can cause similar symptoms to Hereditary sensory and autonomic neuropathy type 1c?
Common look-alikes include diabetes-related nerve damage, alcohol-related nerve damage, and other inherited nerve disorders such as Charcot-Marie-Tooth disease, because all can cause numbness, burning pain, weakness, balance problems, and foot sores. Less often, low vitamin B12, a protein buildup disorder called amyloidosis, or some immune-related nerve conditions can also look similar, especially if symptoms affect both feeling and body functions such as sweating or blood pressure.
History
People living with hereditary sensory and autonomic neuropathy type 1c often deal with problems that build slowly over years, such as reduced feeling in the feet, injuries that are noticed late, or wounds that take longer to heal. That day-to-day pattern was recognized long before doctors had today’s testing tools, when families and physicians could only piece the condition together from what they saw over time.
In the late 1800s and early 1900s, doctors began publishing reports of families in which several relatives developed numbness, pain problems, foot ulcers, and weakness without a clear outside cause. At first, these conditions were grouped broadly as inherited nerve disorders because the main clues came from symptoms and from the way the illness appeared across generations. Some may find it helpful to know that the autonomic part of the name refers to body functions that happen automatically, such as sweating or blood pressure control, which can also be affected in some people.
As medical science evolved, specialists became better at separating different forms of these nerve conditions from one another. Tests of nerve function, more detailed family histories, and closer follow-up showed that not all inherited sensory neuropathies were the same. Over time, hereditary sensory and autonomic neuropathy type 1 was recognized as a group of related disorders that often begin in adolescence or adulthood, and type 1c was identified as one of its more specific forms.
Later, researchers confirmed that hereditary sensory and autonomic neuropathy type 1c has a genetic cause, which helped explain why the condition can run in families and why symptoms may look similar but not identical from one relative to another. This was important because older reports sometimes focused only on severe complications, like chronic sores or infections, while milder early symptoms of hereditary sensory and autonomic neuropathy type 1c could be missed. For many, this can mean years of subtle changes, such as not noticing a blister after a long walk or realizing that temperature sensation is not quite normal.
Today, the history of hereditary sensory and autonomic neuropathy type 1c is understood as part of the larger story of inherited nerve disorders: first recognized through careful observation, then refined through better testing, and now described more precisely through modern genetics. That history matters because it has improved diagnosis, helped families get clearer answers, and made it easier to tell this condition apart from other causes of numbness, pain loss, and foot problems.
