The FAM167B gene helps cells send and receive signals, especially in parts of the body involved in immune activity. If this gene does not work as expected, those signals may become less balanced, which can affect inflammation and may slightly change disease risk. Changes in the FAM167B gene are mostly discussed in medical research rather than as a common cause of a named inherited condition.
What is a gene?
Genes are sections of DNA that hold instructions your cells use to make molecules or regulate processes in the body. Some genes carry the instructions for making proteins, which are the working parts of cells. Other genes mostly control when certain processes happen, where they happen, and how strongly they run. Together, genes affect how the body develops and functions, and they can also shape how you respond to food, stress, or medications.

Overview
FAM167BGene function
What if the gene works
The FAM167B gene makes a protein found in several tissues. It may help support routine cell activity and normal cell signaling.
Risk
What if the gene does not work
Changes in the FAM167B gene can range from milder to more severe and may reduce the amount of FAM167B protein made or change how it folds, which can weaken its normal role in cells.
Treatment
What does that mean for your treatment
A pathogenic or loss-of-function variant in the FAM167B gene does not currently guide treatment or drug choice in clinical guidelines.
Gene function
What if the gene works
Your cells use the FAM167B gene to make a small protein that appears to help with cell to cell communication. It is most closely linked with signaling that helps tissues coordinate everyday activity, including immune activity. This gives a practical picture of what the FAM167B gene does in the body day to day.
The FAM167B gene helps make a protein that is likely released from cells into the surrounding space. That setup fits a signaling role, where one cell influences how nearby cells behave.
Many studies connect this gene with signals used by immune cells to communicate. When it is working as expected, it may support measured, organized immune activity during routine body functions.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These differences are common and are part of normal human diversity, such as differences in appearance, metabolism, or how the body responds to environmental influences. Many variants do not have any noticeable effect and simply represent natural genetic variation. In some cases, though, a variant can change how a gene works more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Changes in the FAM167B gene can alter how much protein a cell makes, how stable that protein is, or how well it interacts with other cell components. Milder variants may cause small shifts in protein shape or activity, while more severe variants can greatly reduce protein production or create a shortened protein that is quickly broken down. This range helps explain how variants influence the FAM167B gene's function at the molecular and cellular level.
How variants are linked to conditions
Current evidence does not yet show a broadly confirmed link between the FAM167B gene and a specific health condition, although research on how variants in the FAM167B gene are linked to conditions is still developing. If you have a confirmed variant in the FAM167B gene, your doctor or genetic counselor can explain what it may or may not mean for you and your family.
A variant is not necessarily a diagnosis
Genetic variants are a routine 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, having a variant linked to a condition suggests a possible association rather than a definite diagnosis, especially when several genes and environmental factors also 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 FAM167B gene. If a test result mentions FAM167B, its meaning usually depends on the exact change found and the wider clinical picture, so discussing personal risk with a doctor or genetic counselor can help.
Inheritance of FAM167B variants
There is not yet a broadly confirmed Mendelian pattern for the inheritance of the FAM167B gene variants tied to a specific human condition. Current evidence does not support describing inheritance of the FAM167B gene variants as clearly autosomal dominant, autosomal recessive, or X linked. The FAM167B gene is located on an autosome, which means you inherit one copy from each parent.
What does my FAM167B result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for FAM167B, though this understanding can change as research develops. If you have a specific FAM167B result and questions about what it could mean for your family, a doctor or genetic counselor can help explain it in the context of your personal and family history.
Genetic information
Genetic testing
How you find out about variants
To look for variants in the FAM167B gene, a genetic test uses blood, saliva, or a cheek swab to read the DNA sequence. FAM167B genetic testing may be part of a multigene panel or wider sequencing, and results usually classify a variant as benign, uncertain, or linked to disease.
When should I consider getting a genetic test?
There is not a broadly established medical reason to test the FAM167B gene on its own. Genetic testing decisions 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
Genetic results can be informative, but the amount they explain varies with the condition and the kind of variant that is present. How your body functions over time is also shaped by many other factors, including lifestyle, environment, age, and medical history. In some conditions, particularly those affected by many genes, genetic information provides context rather than certainty and makes the most sense when considered with the rest of a person’s care. In other situations, a genetic finding can give a clear answer. For medication response, these results can also help make sense of individual experiences.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body responds to medicines. Some people break down a drug faster or slower than others, which can change how strongly it works or how likely side effects are. These differences are common and are one reason the same treatment may help one person more than another. Genetics is only one part of the picture, and age, other health conditions, and other medicines also play a role.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in a person’s genes affect the way they respond to medicines. It studies gene-drug patterns to help explain why the same treatment can work differently in different people. For many medicines, genes influence both how strong a drug’s effects are and how the body handles it. This information can support more informed, personalized treatment choices.

Drugs influenced by the FAM167B gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication response, so questions about medicines, side effects, or your overall health are best discussed with your doctor.
