The PRMT7 gene helps cells control gene activity and keep certain proteins working properly, which supports normal growth and brain development. If both copies of this gene do not work as they should, a person may have delayed development, speech and learning difficulties, short stature, hand or finger differences, and sometimes seizures. PRMT7-related conditions are rare and are usually inherited in an autosomal recessive pattern, meaning both parents often carry one changed copy.
What is a gene?
Genes are sections of DNA that hold instructions your cells use to make molecules or regulate processes in the body. Some genes provide the information needed to produce proteins, the parts of cells that do much of the work. Other genes are mainly involved in controlling when certain processes happen, where they occur, and how strongly they run. Taken together, genes affect how the body develops and functions, and they can also influence how you respond to food, stress, or medications.

Overview
PRMT7Gene function
What if the gene works
The PRMT7 gene helps cells control how other proteins work and how some genes are switched on or off. This supports normal growth, cell repair, and development in several tissues.
Risk
What if the gene does not work
Variants in the PRMT7 gene can cause a condition with short stature, shorter fingers or toes, developmental delay or intellectual disability, and sometimes seizures. Milder and more severe variants can affect how early features appear and how pronounced they are.
Treatment
What does that mean for your treatment
No PRMT7-specific treatment or management approach is currently established. Care is guided by a person’s symptoms rather than by the PRMT7 variant itself. The PRMT7 gene is being studied in early-stage cancer research as a possible drug target and biomarker.
Conditions associated with PRMT7
Gene function
What if the gene works
Your cells use the PRMT7 gene to place small chemical tags on selected proteins. These tags help proteins do the right job at the right time. Understanding how the PRMT7 gene works can make it easier to see how cells organize gene activity and everyday upkeep.
One of the main jobs of the PRMT7 gene is to add small chemical tags called methyl groups to selected spots on proteins. These tags can change how a protein behaves, where it works, and which other proteins it connects with.
By marking proteins that package DNA, the PRMT7 gene helps cells adjust which genes are active and which stay quieter. This supports orderly day to day control of genetic instructions across many cells.
The marks placed by the PRMT7 gene can also help proteins find the right partners at the right time. This keeps routine cell tasks coordinated, including how cells respond to normal demands and organize their internal work.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, and the way the body responds to environmental influences. Many variants do not have any noticeable effect and are simply part of natural genetic variation. In some cases, though, a variant can change how a gene works more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the PRMT7 gene often make the PRMT7 protein unstable, shortened, or much less active, so cells have less working enzyme available. This is how variants influence the PRMT7 gene's function at a cellular level: some changes leave partial activity, while more disruptive variants can remove activity almost completely. That severity range may shape how strongly features linked to PRMT7 appear and, in some people, how early developmental differences are noticed.
How variants are linked to conditions
Variants in the PRMT7 gene are linked to a rare inherited condition called SBIDDS syndrome, short for short stature, differences in finger length, intellectual disability, and seizures. People with two disease causing PRMT7 variants may have developmental delay, learning difficulties, shorter height, and sometimes seizures. This PRMT7 gene condition is uncommon and does not describe the effect of the more common variants seen in the general population.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are common across the general population. Most do not have a direct effect on health and simply contribute to natural human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a definite diagnosis, especially when several genes and environmental factors play a role. In some cases, though, a single well-characterized variant in a specific gene is enough to confirm a diagnosis.
Are there things that can increase or change my risk?
For PRMT7, risk is mainly linked to whether someone inherits changed copies of the gene from both parents. There is not yet broadly confirmed evidence that lifestyle or other outside factors clearly increase or reduce PRMT7-related risk, so personal questions are best discussed with a doctor or genetic counselor.
Inheritance of PRMT7 variants
Variants in the PRMT7 gene linked to PRMT7-related conditions are inherited in an autosomal recessive pattern. This means a person usually inherits one altered copy from each parent, and both parents are often healthy carriers. For families looking into how PRMT7 gene variants are inherited, each pregnancy between two carriers has a 25% chance of resulting in a child with the condition, a 50% chance of a child who is also a carrier, and a 25% chance of a child who inherits neither altered copy. Sons and daughters are affected at the same rate.
What does my PRMT7 result mean for my family?
For families, a PRMT7 result is most often relevant in a recessive pattern, which means parents may be healthy carriers without knowing it. Brothers and sisters could also have the condition or be carriers, and other close relatives may carry the same gene change. This can be especially important when relatives are planning children, because two carriers can pass the condition on to a child.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the PRMT7 gene, a lab can analyze DNA from blood, saliva, or a cheek swab. Genetic testing for PRMT7 variants reads the gene’s code and compares it with a usual sequence to look for changes that may help explain an inherited condition.
When should I consider getting a genetic test?
Consider PRMT7 testing if a child has a pattern of developmental delay or intellectual disability, seizures, short stature, and unusually short fingers or toes, especially when similar features run in the family. Testing can also help if a close relative has a known PRMT7 gene change.
A genetic result is only one part of your health story
Genetic test results can give useful insight, although what they can tell you varies with the condition and the kind of variant found. How your body functions over time is also shaped by many other factors, including lifestyle, environment, age, and medical history. For some conditions, particularly those affected by many genes, genetic information offers context rather than certainty and makes the most sense when viewed together with the rest of a person’s care. In other situations, a genetic finding may give a more definite answer. In areas like medication response, genetic results can also help put personal experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body responds to medicines. Small differences in genes can change how quickly a drug is broken down, how strongly it acts, or how sensitive your body is to it. This helps explain why the same medication may work well for one person, seem less effective for another, or cause more side effects in someone else. These differences are common and are one of several factors, along with age, other health conditions, and other medicines, that can shape treatment response.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can affect a person’s response to medications. By studying links between genes and drugs, it helps explain why the same treatment may work differently from one person to another. For many medicines, genes can influence both how strongly a drug works and how the body handles it. This information can support treatment decisions that are more informed and more individualized. More detailed information on this topic is available in the LearnHub.
Drugs influenced by the PRMT7 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices, so questions about medicines, side effects, or your overall health are best discussed with your doctor.
History
PRMT7 entered the scientific literature in the early 2000s, during a period of rapid interest in genes that control chemical marks on proteins. In recent decades, awareness of this gene’s role has grown as researchers sorted out how it differs from other members of the same gene family. Early studies highlighted PRMT7 because it did not fit neatly into the patterns already described for related genes. From these first observations, research expanded steadily, linking PRMT7 to inherited conditions and to broader questions in cell biology. Its history is mostly a scientific one, shaped by laboratory discoveries rather than public headlines, and it remains an active area of research today.
