The SAMD13 gene helps make a protein that is thought to support how cells control gene activity, especially in tissues that produce blood cells. If the gene does not work as expected, these control signals may be altered, which can affect normal cell growth and blood cell development. Some variants in or near the SAMD13 gene have been linked in research to blood related traits and certain blood cancers, but their effects can vary from person to person.
What is a gene?
A gene is a section of DNA that gives your cells instructions they can use to make molecules or guide processes in the body. Some genes carry the instructions for producing proteins, the working parts of cells. Other genes mainly regulate when certain processes happen, where they happen, and how active they are. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, and medications.

Overview
SAMD13Gene function
What if the gene works
The SAMD13 gene makes a protein with a sterile alpha motif, a part that helps proteins interact with other proteins. This likely supports routine cell signaling and coordination inside cells.
Risk
What if the gene does not work
Variants in the SAMD13 gene can reduce or alter the SAMD13 protein, which likely affects how it binds other proteins inside cells. Milder variants may leave some activity intact, while more severe variants can cause a greater loss of function.
Treatment
What does that mean for your treatment
No SAMD13-specific treatment or management approach is currently established for pathogenic or loss-of-function variants in the SAMD13 gene.
Gene function
What if the gene works
Inside your cells, the SAMD13 gene helps make a protein used in routine cell organization. Its key feature is a sterile alpha motif (a small section that helps molecules attach to each other). Understanding how the SAMD13 gene works in your cells helps show how cells coordinate everyday activity.
The SAMD13 gene makes a protein with a sterile alpha motif (a small section that helps molecules bind). This feature helps the protein join other cell components and support organized signaling inside the cell.
What is a variant?
A genetic variant is a minor difference in the DNA sequence within a gene. These variants are common and are part of normal human diversity, including differences in appearance, metabolism, and the way the body responds to environmental influences. Most have no noticeable effect and simply represent natural genetic variation. Sometimes, though, a variant changes how a gene works more substantially and can contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the SAMD13 gene can change the protein’s shape, stability, or ability to interact with other cell components. In SAMD13 gene variants and protein stability, milder changes may leave some function intact, while more disruptive variants can reduce how much protein is made or produce a shortened protein that works less well. This creates a spectrum of functional effects at the cellular level rather than one single outcome.
How variants are linked to conditions
SAMD13 gene variants do not yet have a broadly confirmed link to a specific health condition, though this can change as research develops. Current evidence on how variants of the SAMD13 gene are linked to conditions is still developing, so a result in this gene is usually interpreted together with your personal and family history. Anyone with a confirmed SAMD13-related diagnosis should follow guidance from their doctor or genetic counselor.
A variant is not necessarily a diagnosis
Genetic variants are common in the general population and are a normal feature of human biology. Most do not have a direct effect on health and simply represent 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 play a role. In some situations, however, 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 isn't yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the SAMD13 gene. If SAMD13 appears on a genetic test, the result is usually interpreted alongside your symptoms, family history, and any other genetic findings.
Inheritance of SAMD13 variants
There is not yet a broadly confirmed disease specific inheritance pattern for the SAMD13 gene, so how SAMD13 variants are inherited in relation to a named condition is still being clarified. SAMD13 is located on chromosome 1, which is an autosome, so a person inherits one copy of the SAMD13 gene from each parent.
What does my SAMD13 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for SAMD13, although this can change as research moves forward. If you have a specific SAMD13 result and want to understand what it could mean for close 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
Genetic testing for variants in the SAMD13 gene usually uses a blood or saliva sample. A laboratory reads the DNA code in the SAMD13 gene and compares it with a reference sequence to look for changes. Results may show a benign variant, a variant of uncertain significance, or a variant linked to a genetic condition.
When should I consider getting a genetic test?
There is not yet a broadly established SAMD13-specific reason for genetic testing in routine care. Testing decisions are usually based on your personal health and family history, and a doctor or genetic counselor can help decide whether broader genetic testing makes sense.
A genetic result is only one part of your health story
A genetic finding can provide meaningful insight, but how much it reveals depends on the condition and the kind of variant involved. Many factors, including lifestyle, environment, age, and medical history, influence how the body functions over time. For some conditions, especially those affected by many genes, genetic information offers context rather than certainty and is best understood together with other parts of care. In other situations, a genetic result may give a clear answer. In areas such as medication response, genetic results can help put individual experiences in perspective.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Two people can take the same drug at the same dose, yet one may get a stronger effect while the other notices less benefit or more side effects. Part of this difference comes from inherited changes that influence how the body breaks down, moves, or responds to a medication. These differences are common and are one reason treatment response can vary from person to person.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in genes can shape the way a person responds to medication. It studies links between genes and drugs to better explain why the same treatment may work differently from one person to another. For many medicines, genes can affect how strongly a drug works or how the body processes it. This information can help guide more informed and more individualized treatment decisions. More about this topic is available in the LearnHub.
Drugs influenced by the SAMD13 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice or dose, so general questions about side effects, new symptoms, or how medicines may affect you are best discussed with your doctor.
