The ANKRD62 gene helps cells divide in an orderly way, especially as the brain forms before birth. This gene plays an important role in early brain growth, so if it does not work properly, some people may be born with a smaller-than-expected head size and later have developmental delay, seizures, or differences seen on brain scans.
What is a gene?
Genes are stretches of DNA that carry instructions your cells can use to make molecules or direct processes in the body. Some genes provide the information needed to produce proteins, the parts of cells that do the work. Other genes mainly control when certain processes happen, where they happen, and how strongly they operate. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications.

Overview
ANKRD62Gene function
What if the gene works
The ANKRD62 gene helps cells divide in an organized way. Its protein appears to support the cell’s internal scaffold during division, which is especially important as the brain grows before birth.
Risk
What if the gene does not work
More disruptive variants in the ANKRD62 gene are linked to a condition affecting brain development, often causing a smaller than usual head size, developmental delay, and intellectual disability. Milder variants may lead to a wider range of features and severity.
Treatment
What does that mean for your treatment
No ANKRD62-specific treatment or drug choice approach is currently established in clinical guidelines. Care is based on the person's symptoms and overall diagnosis rather than on a pathogenic variant in the ANKRD62 gene itself.
Gene function
What if the gene works
ANKRD62 helps cells organize key growth signals during development. Its protein contains ankyrin repeats, which are common building blocks for connecting one protein to another. Understanding the normal function of the ANKRD62 gene helps show how cells coordinate structure, movement, and communication as tissues form.
The ANKRD62 protein acts as a connector that helps other proteins meet and work together inside cells. This supports smooth signaling during normal growth and development.
ANKRD62 supports cell signals that guide how cells move, change shape, and settle into place. These signals help developing tissues form in an orderly way.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These changes are common and help shape normal human diversity, including differences in appearance, metabolism, or how the body responds to environmental influences. Many variants do not have any noticeable effect and are simply part of natural genetic variation. Sometimes, however, a variant can change how a gene functions more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the ANKRD62 gene can change the protein's shape, shorten it, or make it less stable, which may weaken how it interacts with other cell proteins. Some variants also disrupt RNA splicing (the cell’s editing of gene messages), so cells make less usable protein. In looking at how ANKRD62 gene variants affect protein function, milder changes may leave some activity, while more severe variants can greatly reduce or stop the protein from working.
How variants are linked to conditions
At this time, variants in the ANKRD62 gene do not yet have a broadly confirmed link to a specific health condition, though research on ANKRD62 gene variants and health conditions is still developing. Anyone with a confirmed ANKRD62-related diagnosis should rely on guidance from their doctor or genetic counselor rather than general information.
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 reflect natural human diversity. For many genes, carrying a variant associated with a condition indicates a possible link rather than a definite diagnosis, especially when several genes and environmental factors also play a role. In some cases, though, a single well-characterized variant in a specific gene can be enough to confirm a diagnosis.
Are there things that can increase or change my risk?
There is not yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the ANKRD62 gene. If a change in ANKRD62 runs in a family, family history can affect the chance of seeing it again, but day-to-day lifestyle factors have not been clearly shown to change that genetic risk.
Inheritance of ANKRD62 variants
ANKRD62-related conditions are inherited in an autosomal recessive pattern. This means a child usually needs to inherit one changed copy of the ANKRD62 gene from each parent to be affected. Parents who each carry one variant are typically unaffected, and with each pregnancy there is a 25% chance of having an affected child, a 50% chance of having a child who is a carrier, and a 25% chance of having a child with two non-affected copies. In practical terms, ANKRD62 gene inheritance affects sons and daughters equally because this gene is on a non-sex chromosome.
What does my ANKRD62 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific, well-established condition for ANKRD62. For families, that means an ANKRD62 result does not have one clear, widely accepted meaning for relatives in the way some better-known genes do. If you have a specific ANKRD62 result, the family implications depend on the exact change and why testing was done.
Genetic information
Genetic testing
How you find out about variants
Testing for variants in the ANKRD62 gene usually uses a blood sample, saliva, or cheek swab. In ANKRD62 genetic testing, a lab reads the DNA through a multigene panel, exome sequencing, or genome sequencing and classifies any variant using established evidence.
When should I consider getting a genetic test?
There isn't yet a broadly established ANKRD62-specific clinical reason for testing. Decisions about genetic testing are usually based on your symptoms, family history, and whether ANKRD62 is included as part of a larger test panel discussed with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result may offer useful insight, but how much it explains varies by the condition and the type of variant involved. Over time, many factors shape how the body works, including lifestyle, environment, age, and medical history. In some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is best considered alongside other parts of care. In other situations, a genetic result can give a clear answer. In areas such as response to medications, genetic results may 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 genes can change how the body breaks down a drug, moves it through the body, or responds at the drug’s target. This helps explain why the same medicine may work well for one person, seem weaker for another, or cause more side effects in someone else.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect a person’s response to medications. It studies gene and drug patterns to better explain why the same treatment may work differently from one person to another. For many medicines, genes influence how strongly a drug works or how the body handles it. This information can support more informed, individualized treatment decisions.

Drugs influenced by the ANKRD62 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication response, so any concerns about side effects, new symptoms, or how a medicine is working are best discussed with your doctor.
