The FAM135A gene gives cells instructions for making a protein that helps support normal cell activity. If this gene does not work as expected, growth signals inside cells may become less balanced. Some differences in this gene have been found in cancer research, where they may play a role in how tumor cells grow. FAM135A is mainly discussed in research settings rather than everyday public health conversations.
What is a gene?
A gene is a stretch of DNA that provides information your cells use to make molecules or regulate processes in the body. Some genes hold the instructions for producing proteins, the parts of cells that do much of the work. Others mainly control when certain processes happen, where they happen, and how strongly they operate. Taken together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications.

Overview
FAM135AGene function
What if the gene works
The FAM135A gene helps your cells make the FAM135A protein. This protein is thought to support normal cell activity.
Risk
What if the gene does not work
Changes in the FAM135A gene may alter how much FAM135A protein a cell makes or how well it works. Milder variants may partly change protein activity, while more severe variants can greatly reduce or stop it.
Treatment
What does that mean for your treatment
No established treatment or medication choice is currently guided by pathogenic or loss-of-function variants in the FAM135A gene.
Gene function
What if the gene works
When FAM135A is working normally, your cells make the FAM135A protein as part of everyday cell activity. The protein works inside cells and fits into routine cellular processes. This brief overview explains normal FAM135A gene function in the body.
The FAM135A gene provides the code for making the FAM135A protein. This lets cells produce the protein at the right time as part of normal cell activity.
The FAM135A protein works inside cells rather than outside them. In normal cells, it contributes to steady day-to-day cellular function.
What is a variant?
A genetic variant is a minor difference in a gene’s DNA sequence. These differences are common and help shape normal human diversity, including variation 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 changes how a gene works more substantially and may contribute to, or directly cause, a genetic condition.
Genetic variants
What if the gene does not work
Variants in the FAM135A gene can change the RNA message or the protein it makes, which may reduce protein stability, shorten the protein, or weaken how it interacts with other cell parts. In this way, FAM135A gene variants may range from mild changes with little effect to more disruptive variants that greatly lower the amount of working protein. The functional impact often depends on the exact DNA change and where it occurs in the gene.
How variants are linked to conditions
Variants in the FAM135A gene do not yet have a broadly confirmed link to a specific health condition, though this can change as research develops. Current medical genetics sources on how FAM135A variants are linked to conditions have not established a single, widely accepted diagnosis tied to the FAM135A gene. If you carry a variant in the FAM135A gene, your doctor or genetic counselor can interpret it in the context of your own health and family history.
A variant is not necessarily a diagnosis
Genetic variants are a common, normal feature of human biology. Most do not directly affect health and simply contribute to natural differences among people. For many genes, having a variant associated with a condition points to a possible link rather than a confirmed diagnosis, particularly when more than one gene and environmental influences play a role. Still, in some situations, one well-characterized variant in a particular gene is enough to establish 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 FAM135A gene. Anyone with concerns about their personal or family risk can talk with a doctor or genetic counselor.
Inheritance of FAM135A variants
There is not yet a broadly confirmed disease inheritance pattern for the FAM135A gene, so FAM135A gene inheritance is not described in the same clear way as genes linked to well-defined dominant or recessive conditions. As research develops, this may become clearer. The FAM135A gene is located on an autosome, which means you inherit one copy from your mother and one copy from your father.
What does my FAM135A result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for the FAM135A gene. Understanding of this gene may change as research grows. If you have a specific FAM135A result and want to know what it could mean for relatives, a doctor or genetic counselor can explain it in the context of your family history.
Genetic information
Genetic testing
How you find out about variants
FAM135A genetic testing is done by reading DNA from a blood sample, cheek swab, or saliva sample. A lab may look only at the FAM135A gene or include it in a larger panel, exome, or genome test, then compares your DNA sequence with the usual pattern to identify variants.
When should I consider getting a genetic test?
There is not yet a broadly established, FAM135A-specific clinical reason for genetic testing in routine care. Testing decisions are usually based on your personal health and family history and are best made with a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic results can provide useful insight, but how much they reveal varies by the condition and the specific type of variant. Over time, many factors shape how the body works, including lifestyle, environment, age, and medical history. For some conditions, especially those affected by many genes, genetic information offers 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 like medication response, these results can also help put individual experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body handles medicines, so the same treatment may work well for one person but less well for another. Some gene changes influence how quickly a drug is broken down or how strongly the body responds to it. This is common and can shape both the benefit of a treatment and the chance of side effects. Medication response is also influenced by other factors, including age, liver and kidney function, other medicines, and overall health.
What is Pharmacogenetics?
Pharmacogenetics looks at how genetic differences shape a person’s response to medications. It examines links between genes and drugs to better understand why the same treatment may work differently in different people. For many medicines, genes can affect how strongly a drug works or how the body processes it. This information can help support treatment decisions that are more informed and individualized. To explore this subject in more detail, you can find more information in the LearnHub.
Drugs influenced by the FAM135A gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in how medicines work, so questions about side effects, treatment response, or other health concerns are best discussed with your doctor.
