The FAM24B gene gives cells instructions for making a protein involved in normal cell function. Most variants in this gene have little effect on how your body works, but a more disruptive variant may interfere with the gene’s usual job and alter how cells function. Any health effect depends on the specific variant and how strongly it changes the protein.
What is a gene?
Genes are stretches of DNA that provide cells with instructions to make molecules or direct processes in the body. Some genes hold the directions for producing proteins, the parts of cells that do much of the work. Other genes mainly regulate when certain processes happen, where they take place, and how strongly they run. Taken together, genes affect how the body develops and works, and they can shape how you respond to food, stress, or medications.

Overview
FAM24BGene function
What if the gene works
The FAM24B gene helps cells make the FAM24B protein. This protein may play a part in normal cell function.
Risk
What if the gene does not work
Milder and more severe variants in the FAM24B gene can reduce how much FAM24B protein a cell makes or change its shape. That can weaken the protein’s usual interactions inside the cell and lower its normal activity.
Treatment
What does that mean for your treatment
No treatment or management approach is currently established specifically for pathogenic variants in the FAM24B gene.
Gene function
What if the gene works
FAM24B supports normal cell work through the protein your cells make from it. Understanding how the FAM24B gene works in the body helps show how genes guide everyday protein production inside cells.
The FAM24B gene carries the code your cells use to make the FAM24B protein. When it is working properly, cells can read that code, build the protein, and support routine cell activity.
What is a variant?
A genetic variant is a small change in the DNA sequence within a gene. These changes are common and help account for normal human diversity, including differences in appearance, metabolism, or how the body responds to environmental influences. Many variants have no noticeable effect and are simply part of natural genetic variation. In some cases, though, 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 FAM24B gene can change how much of its protein a cell makes or how stable that protein is. In terms of how FAM24B gene variants affect protein function, some changes may slightly alter the protein’s shape or cell interactions, while more severe variants can greatly reduce protein production or stop a full-length protein from being made. This creates a spectrum of functional impact, from milder partial loss to more marked loss of activity.
How variants are linked to conditions
Variants in the FAM24B gene do not yet have a broadly confirmed link to a specific health condition, and a clear FAM24B gene and disease association has not been established across human genetics research. If you carry a reported variant in this gene, its meaning is usually interpreted alongside your symptoms, family history, and the rest of your genetic test findings.
A variant is not necessarily a diagnosis
Genetic variants are common across the general population and are a normal feature of human biology. Most do not directly affect health and instead reflect normal human diversity. For many genes, carrying a variant associated with a condition points to a possible link rather than a definite diagnosis, especially when more than one gene and environmental factors play a role. In some situations, 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?
There is not yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the FAM24B gene. If a test finds a change in FAM24B, the meaning usually depends on the exact change and your personal and family history.
Inheritance of FAM24B variants
At present, there is not a broadly confirmed disease specific inheritance pattern for the FAM24B gene, so how are variants of the FAM24B gene inherited is not yet answered with a single established mode such as autosomal dominant or autosomal recessive. FAM24B is located on an autosome, which means you inherit one copy of the FAM24B gene from your mother and one copy from your father. As research develops, a clearer inheritance pattern may emerge for particular FAM24B related findings.
What does my FAM24B result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for FAM24B, though this can change as research grows. If you have a FAM24B result and want to understand what it could mean for relatives, a doctor or genetic counselor can help explain it in the context of your family history and test findings.
Genetic information
Genetic testing
How you find out about variants
FAM24B genetic testing usually happens as part of broader DNA tests, such as multigene panels or exome sequencing, using a blood or saliva sample to look for variants in the FAM24B gene. Results may identify a variant, show no clearly relevant change, or find a change whose health meaning is still being clarified.
When should I consider getting a genetic test?
There isn't yet a broadly established, FAM24B-specific reason for genetic testing. Decisions about testing are usually based on your health, family history, and the condition being looked into, together with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic finding can provide useful insight, yet how much it reveals varies by the condition and the type of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, influence how the body works. For some conditions, especially those shaped by many genes, genetic information offers context rather than certainty and is best understood alongside 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 perspective.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small inherited differences can change how the body absorbs, breaks down, transports, or reacts to a drug, so the same treatment may work better for one person and less well for another. This is a common part of human biology and can influence both how well a medicine helps and how sensitive someone is to side effects.
What is Pharmacogenetics?
Pharmacogenetics looks at how genetic differences shape a person’s response to medications. It examines links between genes and drugs to help 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 FAM24B gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medicine choice or dose. If you have side effects, a medicine is not working as expected, or you have concerns about treatment, talk with your doctor or pharmacist.
