The FAM120C gene gives cells instructions for a protein involved in passing signals inside the cell and handling RNA, the working copy of genetic instructions. The protein made by this gene helps your cells keep these messages organized. If the FAM120C gene does not work properly, cells may have more trouble coordinating normal activity, which can affect how tissues function.
What is a gene?
Genes are stretches of DNA that hold information your cells use to make molecules or manage processes in the body. Some genes carry the instructions for making proteins, the working parts of cells. Other genes mainly help control when certain processes happen, where they take place, and how strongly they operate. Together, genes affect how the body develops and works, and they can also influence how you respond to food, stress, or medications.

Overview
FAM120CGene function
What if the gene works
The FAM120C gene helps make a protein that supports routine cell signaling and how cells handle other proteins.
Risk
What if the gene does not work
Variants in the FAM120C gene can range from milder to more severe and may weaken its role in RNA handling and cell signaling. This mainly disrupts how cells coordinate internal messages, without a clearly defined single disease pattern.
Treatment
What does that mean for your treatment
No FAM120C-specific treatment or management approach is currently established for people with a pathogenic variant in the FAM120C gene.
Gene function
What if the gene works
Your cells use the FAM120C gene in everyday RNA handling. Its protein helps manage RNA, the working copy of genetic instructions, and helps coordinate groups of proteins inside the cell. Overall, FAM120C gene function in the body centers on keeping routine cell messages organized.
The FAM120C gene helps cells manage RNA, the temporary copy of DNA instructions used to make proteins. Its protein can bind these messages and support how they are processed and used.
This gene also helps bring groups of proteins together so they can work in a coordinated way inside cells. That support helps routine message reading and other daily cell tasks run more smoothly.
What is a variant?
A genetic variant is a minor difference in the DNA sequence within a gene. These differences are common and are part of normal human diversity, including variations in appearance, metabolism, and the way the body responds to environmental influences. Many variants do not have any noticeable effect and simply represent natural genetic variation. Sometimes, though, a variant changes how a gene works more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
How variants influence the FAM120C gene's function depends on the type of DNA change. Some variants may slightly alter the FAM120C protein's shape or stability, which can weaken how it interacts with other molecules inside the cell. More disruptive variants, including changes that create an early stop signal or disrupt how the gene's message is put together, can leave the cell with much less protein or none at all. This creates a spectrum from milder to stronger loss of function.
How variants are linked to conditions
Variants in the FAM120C gene do not yet have a broadly confirmed link to a specific health condition, and research may refine this over time. Anyone with a confirmed finding in the FAM120C gene should use advice from their doctor or genetic counselor to understand what it means for their own health and family.
A variant is not necessarily a diagnosis
DNA variants are a normal feature of human biology and are common across the general population. Most do not have a direct effect on health and instead reflect natural human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a certain diagnosis, especially when several genes and environmental factors play a role. In some situations, 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 FAM120C gene. If a change in FAM120C is found on testing, a doctor or genetic counselor can help explain what it may mean for you and your family.
Inheritance of FAM120C variants
There is not yet a broadly confirmed disease specific inheritance pattern for the FAM120C gene, so how FAM120C gene variants are inherited in relation to a defined genetic condition is still being clarified. The FAM120C gene is located on an autosome rather than a sex chromosome, which means you inherit one copy from each parent and inheritance would not be expected to differ between sons and daughters.
What does my FAM120C result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for FAM120C, although this can change as research develops. If you have a specific FAM120C 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.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a change in the FAM120C gene, a lab can analyze DNA from a blood sample, saliva, or cheek swab. This genetic testing for FAM120C variants reads the gene’s code and compares it with a reference sequence to look for variants. Results may show a variant that is benign, uncertain, or linked to disease.
When should I consider getting a genetic test?
There isn’t yet a broadly established, FAM120C-specific clinical reason for testing. Decisions about genetic testing are best made with a doctor or genetic counselor based on your health history and family history.
A genetic result is only one part of your health story
Genetic test findings can be informative, yet what they tell you depends on both the condition involved and the specific variant found. Over time, factors such as age, environment, lifestyle, and medical history also shape how the body functions. In conditions affected by many genes, genetic information often provides context rather than certainty and is best considered alongside other parts of care. In other situations, a genetic result may give a clear answer. In areas like medication response, these 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. Two people can take the same treatment and have different results because their bodies may absorb, break down, or respond to a drug in different ways. These inherited differences are common and can influence how well a medicine works or how sensitive someone is to side effects.
What is Pharmacogenetics?
Pharmacogenetics is the area of study that examines how genetic differences can affect response to medications. By looking at relationships 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 how strongly a drug works or how the body processes it. This information can support treatment decisions that are more informed and more individualized.

Drugs influenced by the FAM120C gene
When should I seek medical advice?
There is not yet a broadly confirmed role for changes in this gene in predicting how medicines will work, so questions about treatment choices, side effects, or medication safety are best discussed with your doctor.
