The SAMD14 gene helps regulate cell signals, especially in blood-forming cells, and if it does not work properly, normal blood cell development may be affected. This gene plays an important role in how cells grow, survive, and mature. Researchers also study the SAMD14 gene in cancer because changes in its activity may influence how some tumor cells behave.
What is a gene?
A gene is a stretch of DNA that carries 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. Other genes mostly help direct when certain processes happen, where they take place, and how strongly they operate. Together, genes affect how the body grows and works, and they can influence how you respond to food, stress, or medications.

Overview
SAMD14Gene function
What if the gene works
The SAMD14 gene helps control signals that support developing blood cells, especially red blood cell precursors. Its protein appears to support normal cell growth and maturation in the bone marrow.
Risk
What if the gene does not work
Changes in the SAMD14 gene can range from milder to more severe and may reduce how well blood-forming cells respond to growth signals, especially during red blood cell development. This can weaken cell signaling and support functions inside these cells.
Treatment
What does that mean for your treatment
For people with a pathogenic or loss-of-function variant in the SAMD14 gene, no SAMD14-specific treatment or drug selection approach is currently established in clinical guidelines.
Gene function
What if the gene works
The SAMD14 gene helps certain cells handle growth signals in an organized way. Its activity is especially important in blood-forming tissue, where young red blood cells need clear instructions to grow and mature. This helps explain how the SAMD14 gene supports red blood cell production as part of normal blood cell function.
The protein made from the SAMD14 gene has a section that helps it connect with other proteins. These connections let cells organize important tasks instead of reacting in a scattered way.
The SAMD14 gene helps cells pass along growth signals inside the cell. This supports steady communication that guides normal cell growth and timing.
In blood-forming tissue, the SAMD14 gene supports the growth and maturation of young red blood cells. This helps the body maintain normal red blood cell production for oxygen delivery.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, and the way the body reacts to environmental influences. Many variants do not have any noticeable effect and are simply part of natural genetic variation. Sometimes, though, a variant changes how a gene works more significantly and can contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Changes in the SAMD14 gene can alter how much SAMD14 protein a cell makes, how stable that protein is, or how well it interacts with other signaling proteins. Some variants have mild effects, while more disruptive variants can sharply reduce or abolish protein activity, so the way SAMD14 gene variants affect cell signaling may differ from one change to another.
How variants are linked to conditions
The SAMD14 gene does not yet have a broadly confirmed link to a specific health condition, though research on SAMD14 gene variants and disease is still evolving. If you carry a confirmed variant in the SAMD14 gene, its meaning is best interpreted with your doctor or genetic counselor alongside your symptoms and family history.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and occur commonly throughout the general population. Most do not directly influence health and simply reflect natural variation among people. In many genes, carrying a variant associated with a condition points to a possible connection rather than a confirmed diagnosis, especially when multiple genes and environmental factors are also involved. In some situations, though, one well-characterized variant in a particular 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 SAMD14 gene. If a SAMD14 finding appears on genetic testing, the effect usually depends on the exact change and the health condition being evaluated, so personal risk is best reviewed with a doctor or genetic counselor.
Inheritance of SAMD14 variants
There is not yet a broadly confirmed Mendelian pattern for how SAMD14 gene variants are inherited in relation to a specific human condition. Current evidence does not support describing SAMD14 as clearly autosomal dominant, autosomal recessive, or X linked for a well established SAMD14 related disease. For families asking how SAMD14 gene variants are inherited, it helps to know that the SAMD14 gene is located on chromosome 17, which is an autosome. That means each person inherits one copy from each parent.
What does my SAMD14 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific, recognized health condition for SAMD14. If you have a SAMD14 result and want to understand what it could mean for your relatives, a doctor or genetic counselor can explain it in the context of your exact finding and family history.
Genetic information
Genetic testing
How you find out about variants
A lab can look for changes in the SAMD14 gene using a blood sample, saliva, or a cheek swab. Genetic testing for SAMD14 variants reads the gene’s DNA code and compares it with the usual sequence to identify variants that may help explain a test result.
When should I consider getting a genetic test?
There is not yet a broadly established SAMD14-specific reason for genetic testing in routine care. Testing decisions are best made with a doctor or genetic counselor based on your health history, symptoms, and family history.
A genetic result is only one part of your health story
Genetic results can provide meaningful insight, but how much they reveal depends on the condition and the type of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, also shape how the body works. For some conditions, especially those influenced 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 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. Two people can take the same treatment and have different results because their bodies may absorb, break down, or respond to the 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. Medication response is also shaped by age, other health conditions, and other medicines, so genes are one part of the picture.
What is Pharmacogenetics?
Pharmacogenetics is the area of study that examines how genetic differences affect the way a person responds to medications. It looks at relationships between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medicines, genes can influence both how strongly a drug works and how the body handles it. This information can support treatment decisions that are more informed and more personalized.

Drugs influenced by the SAMD14 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 questions about medicines, side effects, or general health are best discussed with your doctor or pharmacist.
