The PARP10 gene makes a protein that helps cells respond to DNA stress and supports normal growth and division. This gene plays an important role in repairing everyday damage in genetic material and helping cells copy DNA in a steady way. If it does not work properly, cells may struggle to handle damage, which can affect growth and brain development. Rare harmful variants in the PARP10 gene have been linked to developmental delay and short stature.
What is a gene?
Genes are stretches of DNA that hold instructions your cells use to make molecules or regulate processes in the body. Some genes provide the directions for producing proteins, which are the working parts of cells. Other genes mainly help determine when certain processes happen, where they occur, and how active they are. Together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, or medications.

Overview
PARP10Gene function
What if the gene works
The PARP10 gene helps cells manage stress while copying DNA and repairing damage. Its protein also adjusts other proteins, which supports normal cell growth and helps keep everyday cell activity balanced.
Risk
What if the gene does not work
Milder to more severe variants in the PARP10 gene can reduce or abolish the PARP10 protein's activity, which helps cells respond to DNA stress and control growth. This may disrupt protein signaling and normal cell cycle timing.
Treatment
What does that mean for your treatment
No PARP10-specific treatment or management approach is currently established in clinical guidelines for people with a pathogenic variant in the PARP10 gene. The PARP10 gene is being studied in cancer research as a possible drug target and biomarker, but this work has not yet led to routine treatment decisions.
Gene function
What if the gene works
Your cells use the PARP10 gene during routine growth and repair. It helps add a small chemical tag to certain proteins, which can change how those proteins work. This is part of how cells stay organized while copying DNA and responding to everyday stress. Understanding what the PARP10 gene does in your body helps explain how cells keep normal activity on track.
The PARP10 gene makes a protein that attaches a small chemical mark called ADP-ribose to other proteins. This mark acts like a signal, helping cells adjust protein activity, location, or timing during routine work.
During cell division, this gene helps cells cope when DNA copying slows or briefly pauses. It supports a controlled restart so the copying process can continue more smoothly.
PARP10 helps coordinate signals that guide orderly cell growth and division. By fine tuning key proteins, it supports steady progress through the normal steps a cell follows before it splits.
What is a variant?
A genetic variant is a minor change in the DNA sequence of a gene. These changes are common and help shape normal differences among people, such as appearance, metabolism, or the way the body responds to environmental influences. Many variants do not cause any noticeable effect and are simply part of natural genetic variation. In some situations, though, a variant can more substantially change how a gene functions and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
To understand how PARP10 gene variants affect protein function, some changes in the PARP10 gene can make the protein less stable, shorten it, or reduce its ability to add small chemical tags called ADP-ribose to other proteins. Milder variants may leave some activity intact, while more severe variants can greatly reduce or stop that activity. In cells, this can weaken protein interactions and the response to DNA replication stress, which is the strain that happens when DNA is being copied.
How variants are linked to conditions
Variants in the PARP10 gene do not yet have a broadly confirmed link to a specific health condition, although research on PARP10 gene variants linked to conditions is still evolving. If you have a confirmed variant in the PARP10 gene, your doctor or genetic counselor can explain what it may mean for your health and family in the context of your personal medical history.
A variant is not necessarily a diagnosis
Genetic variants are a usual feature of human biology and are widely found across the general population. Most do not directly affect health and simply contribute to normal human variation. For many genes, having a variant associated with a condition points to a possible link rather than a certain diagnosis, particularly when several genes and environmental influences also play a part. In some situations, though, one well-characterized variant in a particular gene is enough to confirm a diagnosis.
Are there things that can increase or change my risk?
There isn't yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the PARP10 gene. Risk, if any, may depend on the exact genetic change and a person's overall health and family history. Anyone concerned about personal risk should speak with a doctor or genetic counselor.
Inheritance of PARP10 variants
There is not yet a broadly confirmed, disease-specific Mendelian pattern for how PARP10 gene variants are inherited in people. In practice, PARP10 gene inheritance follows the usual rule for genes on the nonsex chromosomes: you receive one copy from each parent. The PARP10 gene is located on chromosome 8, which is an autosome, so a variant could be passed down through either side of the family and is not limited to sons or daughters. As research develops, the inheritance picture for PARP10-related health effects may become clearer.
What does my PARP10 result mean for my family?
There isn't yet a broadly confirmed inheritance pattern tied to a specific condition for the PARP10 gene, though this understanding can change as research develops. If you have a specific PARP10 result and questions about what it could mean for your family, a doctor or genetic counselor can explain it in the context of your result and family history.
Genetic information
Genetic testing
How you find out about variants
Variants are found with genetic testing for variants in the PARP10 gene, usually from a blood or saliva sample. A lab reads the DNA sequence of the PARP10 gene and compares it with a reference sequence to look for changes, then classifies any finding as benign, uncertain, or pathogenic.
When should I consider getting a genetic test?
There is not yet a broadly established PARP10-specific reason for routine genetic testing. Decisions about testing are usually based on your personal health history, symptoms, and family history, together with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can be informative, but how much it reveals depends on the condition and the type of variant involved. Over time, many other factors, including lifestyle, environment, age, and medical history, also shape how the body functions. For some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is most useful when considered with other parts of care. In other situations, a genetic result may give a clear answer. In areas like medication response, genetic results can also help put individual experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small differences in DNA can change how the body breaks down a drug, moves it through the body, or responds to it at its target. This helps explain why the same medicine may work well for one person, have less effect in another, or cause more side effects in someone else.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can shape a person’s response to medications. By looking at the relationship between genes and drugs, it helps explain why the same treatment may work differently from one person to another. For many medicines, genes affect how strongly a drug works or how the body processes it. This information can support more informed, personalized treatment decisions.

Drugs influenced by the PARP10 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding how medicines are chosen or used. If you have questions about side effects, new symptoms after starting treatment, or how your medicines may interact with your health conditions, talk with your doctor or pharmacist.
History
PARP10 entered the scientific literature in the early 2000s, during a period when researchers were identifying more members of the PARP gene family. Initially understood only through visible traits, later recognized as tied to a specific gene, this broader family drew attention because of its role in basic cell processes and cancer research. Building on this early work, scientists began mapping where the PARP10 gene is active and how it differs from other PARP genes. Over time, descriptions became more precise as laboratory methods improved and genetic databases expanded. PARP10 has remained mainly a research gene rather than a public facing one, with its history shaped more by steady scientific study than by a single landmark event.
