Distal arthrogryposis type 1c is a rare genetic condition present from birth that mainly affects the hands and feet. Many people first hear about Distal arthrogryposis type 1c when a baby is born with stiff joints, clenched fingers, or feet that turn inward. The early signs of Distal arthrogryposis type 1c usually appear in infancy, but not everyone will have the same experience. It is usually a lifelong condition, and treatment focuses on improving movement and function with stretching, physical or occupational therapy, splints, and sometimes surgery. Life expectancy is often near typical when Distal arthrogryposis type 1c occurs on its own, though daily impact can vary from mild to more limiting.
How many people live with Distal arthrogryposis type 1c?
Global and U.S. estimates for how many people are living with distal arthrogryposis type 1C are not consistently reported by a single authoritative source. It is considered exceptionally rare, and published medical references do not give a dependable direct count for either the world or the United States.
Overview
Distal arthrogryposis type 1cSymptoms
Distal arthrogryposis type 1c mainly affects the hands and feet. Many living with distal arthrogryposis type 1c are born with stiff, bent fingers or toes, limited joint movement, and sometimes clubfoot, while strength and thinking are usually typical.
Outlook and prognosis
For many living with distal arthrogryposis type 1c, joint stiffness is lifelong but usually does not keep getting worse. Life expectancy is typically normal, and early therapy, stretching, splints, or surgery can improve comfort, mobility, and daily hand and foot function.
Causes and risk factors
Distal arthrogryposis type 1C is caused by a gene change, often inherited from an affected parent, though it can also begin new in a child. Family history raises risk. Lifestyle and environmental factors do not cause it.
Genetic influences
Genetics are very important in distal arthrogryposis type 1c, because it is usually caused by a disease-causing genetic change, often in the MYBPC1 gene. These variants affect muscle function before birth and can run in families.
Diagnosis
Diagnosis of Distal arthrogryposis type 1c usually starts with clinical features seen at birth or in early childhood, especially joint contractures. Doctors often confirm the genetic diagnosis of Distal arthrogryposis type 1c with genetic tests.
Treatment and drugs
Treatment for distal arthrogryposis type 1c focuses on improving joint movement and daily function, often with stretching, splints, and physical or occupational therapy. Some people also benefit from surgery to release tight tissues or better position hands and feet.
Symptoms
Many living with distal arthrogryposis type 1C are born with stiff joints in the hands and feet, so everyday tasks like grasping small objects or finding comfortable shoes can take extra effort. For many people with distal arthrogryposis type 1C, the early features of distal arthrogryposis type 1C are noticeable at birth or soon after, although the exact pattern can vary. The main signs are joint contractures, meaning some joints stay partly bent or turned and do not move through a full range.
Many people with distal arthrogryposis type 1C are born with fingers that stay bent and may not fully straighten. This can make writing, fastening buttons, or picking up small items harder.
The wrists may turn inward or have a limited range of motion from birth. Daily tasks such as dressing, washing, or gripping objects can take more effort.
One or both feet may point inward and downward, which is often called clubfoot. In milder cases, the feet may be high-arched or less flexible, which can affect balance and shoe fit.
Toes can be curled, stiff, or overlap each other. This may lead to rubbing in shoes and discomfort with longer periods of standing or walking.
How people usually first notice Distal arthrogryposis type 1c?
Distal arthrogryposis type 1C is usually first noticed at birth or on early newborn exams, when a baby’s hands and feet look unusually stiff and do not move through a full range, often with fingers that stay bent, overlapping digits, or feet turned inward. In many living with distal arthrogryposis type 1C, the first signs of distal arthrogryposis type 1C are joint contractures, meaning joints are tight and harder to straighten, while strength and thinking are often otherwise typical. Families or doctors may also notice that dressing, diapering, or stretching the arms, hands, or feet feels harder than expected, which usually leads to an orthopedic or genetics evaluation early in life.
Types of Distal arthrogryposis type 1c
No distinct types of Distal arthrogryposis type 1c are widely recognized.
Can I slow down the onset of symptoms?
No, not in a meaningful way: distal arthrogryposis type 1c is a genetic condition, and the joint stiffness and limited movement usually begin before birth, so there is no good evidence that lifestyle changes or medicines can delay the start of symptoms. Research is ongoing, but right now treatment focuses on helping after birth, often with early therapy, stretching, and splints to support movement and daily function rather than preventing the condition from starting. If this condition runs in your family, genetic counseling may help you understand future pregnancy risks, and early care can still improve function even though it cannot prevent the condition.
What genetics can tell you about symptoms
For people with distal arthrogryposis type 1C, genetics can help explain why joint stiffness and contractures tend to affect the hands and feet and why symptoms can be milder in some families and more limiting in others. The genetic change linked to this condition is thought to affect how certain muscle fibers tighten and relax, which can influence which joints are involved, how severe the contractures are, and sometimes whether weakness or movement limits are more noticeable. Even so, genetics cannot predict everything, because many living with the same condition, including relatives with the same variant, can have symptoms that start at birth but vary in day-to-day impact and severity.
Causes and risk factors
Many people with distal arthrogryposis type 1c are born with stiff fingers, hands, or feet because of a change in the MYBPC1 gene, which helps muscles contract normally before birth. This gene change can be inherited from a parent, and in some families it appears for the first time in one child. The main risk factor is family history, especially if a parent or close relative had similar joint tightness at birth. Risk can vary widely from person to person. Lifestyle and everyday exposures do not usually cause distal arthrogryposis type 1c, but biological factors such as reduced movement in the womb may affect how strongly it shows up.
What are the most common causes or risk factors?
Distal arthrogryposis type 1c is most often caused by a change in the MYBPC1 gene, which helps muscles work normally before birth. The biggest risk factor is family history, because this condition is often passed from a parent to a child, although in some families the gene change appears for the first time in the affected child. There are no well-established lifestyle, diet, or common environmental causes.
Environmental and biological risk factors
Distal arthrogryposis type 1c starts before birth and is mainly linked to body-based changes that limit normal joint movement in the womb. When people search for the causes of distal arthrogryposis type 1c, the key idea is that the hands and feet are affected because movement before birth is reduced. Doctors often group risks into internal (biological) and external (environmental). For this condition, clear environmental triggers have not been firmly established.
Lower movement in the womb is the main biological factor tied to distal arthrogryposis type 1c. If joints do not move enough before birth, they can become stiff and settle into fixed positions.
Differences in how muscles tighten and how tendons pull on joints before birth can increase the chance of this pattern of contractures. This mainly affects the hands, feet, and other joints farther from the center of the body.
Limited space in the uterus, low amniotic fluid, or a multiple pregnancy can reduce fetal movement and may contribute to joint stiffness in general. These factors are not a common or proven cause of distal arthrogryposis type 1c, but they may add mechanical strain before birth.
Distal arthrogryposis type 1c has not been strongly linked to routine day-to-day exposures, diet, or stress during pregnancy. Plenty of people with similar exposures live without developing the condition.
Genetic risk factors
The main known genetic cause of distal arthrogryposis type 1c is a change in MYBPC1, a gene that helps skeletal muscles work properly before birth. When this gene does not work as expected, movement in the womb may be reduced, which can contribute to tight joints at birth. The condition is usually passed down in an autosomal dominant pattern, so one altered copy can be enough. People with the same risk factor can have very different experiences.
MYBPC1 changes: In many families, the genetic causes of distal arthrogryposis type 1c trace back to a disease-causing change in MYBPC1. This gene helps support normal muscle contraction and muscle structure before birth.
Dominant inheritance: This condition is usually inherited in an autosomal dominant pattern. A child can be affected after inheriting one altered copy from either parent.
Affected parent: Having an affected parent is the clearest inherited risk factor. If a parent carries the gene change, each pregnancy has a 1 in 2, or 50%, chance of passing it on.
New change: Sometimes the gene change happens for the first time in a child, known as a de novo change. When this happens, there may be no earlier family history.
Lifestyle risk factors
Distal arthrogryposis type 1c is an inherited condition, so lifestyle habits do not cause it. However, how lifestyle affects Distal arthrogryposis type 1c can be important for joint stiffness, pain, fatigue, hand function, walking comfort, and day-to-day independence. The most helpful habits are the ones that protect joint motion, support muscle endurance, and reduce strain on already tight or limited joints.
Too little movement can allow already stiff joints to become harder to use in daily life. Regular, low-impact activity and prescribed stretching or therapy exercises may help preserve mobility, balance, and function in the hands and feet.
Repetitive gripping, prolonged standing, and high-impact exercise can overload joints that already move abnormally. Pacing tasks, taking breaks, and choosing lower-impact activities may reduce pain and help prevent worsening functional limits.
Extra body weight can increase stress on the feet, ankles, knees, and hips during walking and standing. Keeping weight in a healthy range may improve endurance and make mobility aids, braces, or orthotics more effective.
Unsupportive or poorly fitting shoes can worsen pressure points, instability, and discomfort in feet affected by contractures or altered alignment. Supportive footwear and consistent use of prescribed inserts or braces may improve gait and lower fall risk.
Risk prevention
Because distal arthrogryposis type 1c is a genetic condition present from birth, there is usually no known way to prevent the condition itself. For many living with distal arthrogryposis type 1c, prevention means lowering the chance of stiffness, pain, loss of function, and other complications over time. Prevention is flexible—it adapts to your life and health background. Early, regular care also helps spot changes that can affect walking, hand use, or other early symptoms of distal arthrogryposis type 1c.
Physical and occupational therapy started early can help protect joint movement and support daily skills like dressing, writing, or walking. Regular stretching and guided exercises are used to reduce worsening tightness and improve function.
Gentle range-of-motion work, good positioning, and well-fitted splints or braces may help prevent joints from becoming more fixed over time. These steps are usually tailored to the hands, feet, ankles, or other areas affected by distal arthrogryposis type 1c.
Regular visits with specialists can catch foot problems, contractures, or spine changes before they interfere more with comfort and mobility. Prevention works best when combined with regular check-ups.
Staying active with low-impact movement can help maintain strength, balance, and endurance without putting excessive strain on stiff joints. Some may find that swimming, cycling, or guided home exercise is easier than high-impact sports.
Can you prevent Distal arthrogryposis type 1c?
No, distal arthrogryposis type 1c cannot usually be prevented because it is caused by a gene change and begins before birth. If it runs in your family, meeting with a genetics specialist before pregnancy may help you understand the chance of passing it on and what testing options are available.
Transmission
Distal arthrogryposis type 1c is not infectious, so it cannot be passed from one person to another through touch, coughing, sex, food, or everyday contact. Instead, the genetic transmission of Distal arthrogryposis type 1c usually happens within families.
In many families, how Distal arthrogryposis type 1c is inherited follows an autosomal dominant pattern, which means a child can develop it if they inherit one altered copy of the related gene from either parent. If a parent is living with Distal arthrogryposis type 1c, each pregnancy often carries a 1 in 2, or 50%, chance of passing it on. Sometimes it starts with a new genetic change in a child, so there may be no earlier family history.
When to test your genes
Consider genetic testing when a baby or child is born with fixed hand or foot contractures, especially if similar findings run in the family. Testing is mainly used to confirm distal arthrogryposis type 1C, clarify inheritance and recurrence risk, and help tailor orthopedic, therapy, and family-planning decisions.
Diagnosis
Many living with distal arthrogryposis type 1c are first evaluated when hand or foot contractures are noticed at birth or in early childhood, especially if joints seem stiff but thinking, growth, and general health are otherwise typical. Diagnosis is usually based on the pattern of physical findings and then confirmed with genetic testing. Because this is a rare inherited condition, the genetic diagnosis of distal arthrogryposis type 1c may also involve ruling out other causes of congenital joint contractures.
Doctors look for contractures that mainly affect the hands and feet, such as permanently bent fingers, overlapping fingers, clubfoot, or limited ankle movement. They also check how severe the stiffness is and whether other joints are involved.
The medical team reviews when the joint changes were first noticed and whether they have stayed stable or changed over time. A detailed family and health history can help show whether similar findings run in the family.
Diagnosis depends on recognizing a specific pattern of distal joint contractures without the broader findings seen in some other syndromes. Doctors also look for clues that point away from muscle, nerve, or brain conditions.
A blood or saliva test can look for a disease-causing change in a gene linked to this condition, most often MYBPC1. This can confirm the diagnosis of distal arthrogryposis type 1c and help with family counseling.
How is Distal arthrogryposis type 1c diagnosed?
Distal arthrogryposis type 1C is usually diagnosed by a doctor who looks for the typical pattern of joints that are stiff from birth, especially in the hands and feet, and asks about early movement problems and any family history of similar findings. The doctor may also examine the muscles and nerves, and sometimes use X-rays or other tests, to make sure the stiffness is not caused by a different condition. A genetic test using a blood or saliva sample can help confirm the diagnosis by finding the inherited change linked to this type.
Stages of Distal arthrogryposis type 1c
Distal arthrogryposis type 1c does not have defined progression stages. This is because it is usually present from birth and tends to be a stable pattern of joint stiffness and limited movement rather than an illness that gradually moves from one stage to another. Doctors usually start with a conversation about pregnancy, birth, family history, and the signs of distal arthrogryposis type 1c in newborns, along with a physical exam of the hands, feet, and other affected joints. Monitoring focuses on how joints move over time and whether therapies, splints, or surgery are helping with daily function.
Outlook and prognosis
The outlook for people with distal arthrogryposis type 1c is generally favorable because the condition usually affects joint movement in the hands and feet without causing major problems in intelligence or life-threatening organ disease. Severity varies, but many individuals achieve good function with physical therapy, stretching, splinting, and sometimes orthopedic surgery to improve contractures and mobility. Symptoms are often present from birth and may persist lifelong, yet they do not typically worsen into a progressive muscle-wasting disorder. Most people can expect a normal life span, and there is no well-established evidence that distal arthrogryposis type 1c on its own increases mortality. Long-term outcome depends mainly on how severe the contractures are, whether scoliosis or foot deformities develop, and how early supportive treatment begins. Genetic counseling can also help families understand recurrence risk and what to expect over time.
Long-term effects
For many living with distal arthrogryposis type 1c, the biggest long-term effects are usually ongoing joint stiffness in the hands and feet and the day-to-day limits that can come with it. Long-term effects vary widely, but many people have stable physical differences rather than a condition that steadily worsens over time. The long-term effects of distal arthrogryposis type 1c often depend on which joints are most affected and how much movement is available as a child grows into adulthood.
Tight joints in the fingers, wrists, ankles, or feet often remain over time. This can limit how far a joint bends or straightens, even after early treatment.
Many people have lasting trouble with fine motor tasks such as buttoning clothes, handwriting, opening jars, or using small tools. For some, the hands work well for most daily needs but stay less flexible than usual.
Foot and ankle contractures can affect balance, gait, and how comfortably someone walks long distances. Some may tire more easily or need supportive shoes, braces, or other mobility aids at different ages.
Reduced movement around certain joints can lead to weaker muscles nearby and less endurance with repeated activity. Over years, this may make everyday tasks slower or more effortful, especially when standing, gripping, or climbing stairs.
How is it to live with Distal arthrogryposis type 1c?
Living with distal arthrogryposis type 1C often means adapting to joints in the hands and feet that are stiff from birth, so everyday tasks such as buttoning clothes, writing, opening containers, walking long distances, or finding comfortable shoes can take more time and effort. The experience can vary widely, but many people with this condition benefit from physical or occupational therapy, stretching, splints, adaptive tools, and sometimes orthopedic care to protect mobility and independence. For family members and other close supports, the condition can bring extra planning around daily routines, school, work, and appointments, yet with the right support, many living with distal arthrogryposis type 1C build active, engaged lives and develop practical ways to do things on their own.
Treatment and drugs
Distal arthrogryposis type 1c is usually treated by improving movement and function rather than curing the underlying genetic change, since treatment focuses on stiff joints in the hands, feet, and sometimes other limbs. For many people, treatment begins with small daily steps, such as physical and occupational therapy, stretching, and braces or splints to help keep joints in a better position and make everyday tasks like walking, buttoning clothes, or holding a cup easier. Some children also benefit from serial casting, and if contractures are more severe or do not improve enough, orthopedic surgery may be considered to improve joint position or mobility. Treatment often works best when it starts early and is tailored to the joints involved, with regular follow-up to adjust the plan as a child grows.
Can you cure Distal arthrogryposis type 1c?
No, there is currently no cure for distal arthrogryposis type 1c, because it is a genetic condition that affects how some joints develop and move from birth. Treatment cannot remove the condition, but it can help improve comfort, movement, and daily function through stretching and physical therapy, hand therapy, splints or braces, and sometimes surgery for joints that are very tight or hard to use. Many people living with this condition benefit from ongoing care tailored to which joints are affected and how much stiffness they have.
Non-drug treatment
Daily care for distal arthrogryposis type 1c usually focuses on keeping joints as flexible and functional as possible, while helping with comfort, movement, and everyday tasks like dressing, writing, or walking. Because this condition mainly affects the hands, feet, and other joints through contractures present from birth, treatment is often built around therapy, stretching, bracing, and sometimes surgery rather than medicine. Managing this condition often means adjusting the plan over time as a child grows and goals change. Not every approach works the same way, so care is usually tailored to the joints involved and how much stiffness is limiting daily life.
Physical therapy helps maintain joint range, muscle strength, balance, and walking ability as much as possible. Many living with distal arthrogryposis type 1c start therapy early so stretching and guided movement can support better function over time.
Occupational therapy focuses on hand use and daily tasks such as feeding, buttoning clothes, writing, and personal care. Therapists may also suggest easier ways to do activities when stiff fingers, wrists, or elbows make fine movements harder.
Regular stretching at home can help reduce worsening stiffness and support day-to-day movement. Structured programs, like therapist-taught stretching routines, can help families learn safe ways to work on tight joints without overdoing it.
Splints, braces, or special shoes can help hold joints in a better position and improve function during growth. For many, treatment begins not at the pharmacy, but with devices that support the hands, feet, or ankles during sleep or daily activity.
Your genes may have an impact on how drugs work for you
For people living with distal arthrogryposis type 1c, treatment usually centers on stretching, splints or braces, therapy, and sometimes surgery rather than long-term medicines, so gene-based differences in how drugs work are not a main part of care. There is no well-established evidence that this condition has its own special pattern of medicine response that changes which common drugs work best or cause more side effects. If surgery or pain treatment is needed, doctors still choose medicines carefully based on the whole person, because drug response can vary from one person to another even when it is not clearly tied to this condition.
Pharmacological treatments
For distal arthrogryposis type 1c, medicines do not straighten fixed joints or change the underlying genetic cause. Treatment is usually centered on stretching, splints, therapy, and sometimes surgery, with drugs used mainly to ease pain around daily activity or recovery. Drugs that target symptoms directly are called symptomatic treatments. In practice, this means medicine choices depend more on symptoms such as discomfort than on the early symptoms of distal arthrogryposis type 1c itself.
There is no medication approved specifically for distal arthrogryposis type 1c. For many living with distal arthrogryposis type 1c, medicines are supportive rather than curative and are used only when symptoms such as pain need relief.
Acetaminophen and nonsteroidal anti-inflammatory drugs such as ibuprofen or naproxen may be used for mild to moderate pain. This can be helpful after therapy sessions, long periods of walking, or after orthopedic procedures.
After surgery, doctors may prescribe short-term opioid pain medicines such as oxycodone or hydrocodone in carefully selected cases. These drugs are usually used for only a brief time because of side effects such as sleepiness, constipation, and the risk of dependence.
Genetic influences
Distal arthrogryposis type 1c is a genetic subtype that is usually inherited in an autosomal dominant pattern. That means one altered copy of the related gene can be enough to cause the condition, and it can be passed from parent to child. These genetic changes affect how certain muscles work before birth, so the hands and feet may not move as freely in the womb and some joints can become stiff or fixed. Even with the same gene change, people can have different degrees of contractures, so a parent and child may not be affected in exactly the same way. If you are trying to understand the genetic causes of distal arthrogryposis type 1c or how distal arthrogryposis type 1c is inherited in your family, genetic counseling and testing may help clarify the chance of it happening again.
Is Distal arthrogryposis type 1c genetic?
Genetics are very important in distal arthrogryposis type 1c, because it is usually caused by a disease-causing genetic change, often in the MYBPC1 gene. These variants affect muscle function before birth and can run in families.
Having a genetic risk is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are commonly found in the general population. Most do not have a direct effect on health and are simply part of normal human diversity. For many genes, carrying a variant connected to a condition suggests a possible link rather than a definite diagnosis, especially when several genes and environmental factors are involved. In some situations, though, one well-characterized variant in a particular gene is enough to confirm a diagnosis.
Pharmacogenetics—how genetics influence drug effects
For many families, the biggest question is what a genetic result actually changes in everyday care. In distal arthrogryposis type 1c, the gene change can help confirm the diagnosis and explain why joint stiffness and limited movement were present early on, but it usually does not lead to a single targeted medicine. Genetics is only one factor, and treatment for distal arthrogryposis type 1c is still guided mainly by which joints are affected, how much movement is possible, and whether daily tasks like walking, dressing, or gripping objects are hard. This means care often centers on stretching, physical or occupational therapy, splints or casts, and sometimes surgery, while medicines are used mostly for comfort, such as short-term pain relief after procedures. At this point, there is no well-established pharmacogenetic test that tells doctors which drug will work best specifically for distal arthrogryposis type 1c, although a confirmed genetic diagnosis can help avoid unnecessary testing and support family counseling. If anesthesia or other medications are needed, doctors usually choose them based on your overall health and the planned procedure rather than on the distal arthrogryposis type 1c gene result alone.
Interactions with other conditions
Distal arthrogryposis type 1c mainly affects joint movement in the hands and feet, so day to day the biggest issues are often stiffness, trouble with fine motor tasks, and walking discomfort rather than a separate disease process affecting many organs. It is not usually known for causing major heart, lung, or brain disease, which can be reassuring for many living with distal arthrogryposis type 1c. That said, limited movement in the joints can sometimes go along with muscle tightness, foot problems, or spine curvature, and these may add to pain, fatigue, or difficulty keeping up with daily activities. Doctors call it a comorbidity when two conditions occur together, and in this setting it can matter if someone also has another muscle, nerve, or connective tissue disorder that affects strength, balance, or joint stability. Sometimes the early symptoms of distal arthrogryposis type 1c can resemble other inherited conditions that cause contractures, so careful evaluation helps make sure the diagnosis is correct. If another condition is present, treatment usually works best when orthopedic, rehabilitation, and genetics teams coordinate care.
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 Distal arthrogryposis type 1c?
Conditions most often confused with distal arthrogryposis type 1c are other inherited forms of distal arthrogryposis and arthrogryposis multiplex congenita, a broader term for babies born with stiff joints in more than one part of the body. Some nerve or muscle conditions present from birth, and sometimes severe clubfoot or tight hand joints on their own, can also look similar at first. Doctors usually tell them apart by looking at which joints are affected, whether muscle weakness is present, and whether other body systems are involved.
History
For many living with distal arthrogryposis type 1c, the story of the condition did not begin in a lab. It began with doctors and families noticing a similar pattern: babies born with joints that were stiff or fixed in certain positions, especially in the hands and feet, while thinking, growth, and general health were often otherwise typical. Families and communities once noticed patterns across generations, even before medicine had clear names for the different forms of arthrogryposis.
As medical science evolved, doctors realized that not all joint contracture conditions were the same. What had once been grouped together more broadly was gradually divided into smaller, more specific types based on which joints were affected, how severe the stiffness was, and whether other body systems were involved. This helped distinguish distal arthrogryposis type 1c from other forms of arthrogryposis, especially those that affect larger joints more widely or come with additional medical concerns.
Over time, the way the condition has been understood has changed, and that matters for people trying to make sense of a diagnosis today. Earlier reports relied mostly on what could be seen during an exam, such as curved fingers, clubfoot, or limited movement in the hands and ankles. Later, researchers were able to connect these outward features with changes in how muscles and joints develop before birth, and eventually identified a genetic cause in some families, which helped confirm that distal arthrogryposis type 1c belongs within a broader group of related conditions.
Today, the history of distal arthrogryposis type 1c is still being refined as specialists compare older case reports with newer genetic and clinical studies. That growing knowledge has made diagnosis more accurate and has helped clinicians better explain what the early symptoms of distal arthrogryposis type 1c may look like, how it can vary from one person to another, and why one family’s experience may not look exactly like another’s.
