The STK38 gene gives your cells instructions for a signaling protein that helps control cell growth, cell division, and responses to stress. The protein made by this gene helps your cells keep normal growth and cell cleanup on track. If the STK38 gene does not work properly, cells may handle growth or survival signals less accurately, which can disrupt tissue health and is being studied in cancer and some nerve-related conditions.
What is a gene?
A gene is a stretch of DNA that carries instructions your cells can use to make molecules or regulate processes in the body. Some genes provide the information needed to produce proteins, which are the parts of cells that do the work. Other genes mainly guide when certain processes take place, where they happen, and how strongly they occur. Taken together, genes affect how the body develops and works, and they can also influence how you respond to food, stress, or medications.

Overview
STK38Gene function
What if the gene works
The STK38 gene helps cells manage growth, division, and natural cleanup. It also supports how cells respond to stress, helping tissues stay balanced and organized.
Risk
What if the gene does not work
Milder to more severe variants in the STK38 gene can reduce this cell signaling protein’s activity. That may disturb control of cell growth, the cell cycle, programmed cell death, and responses to cellular stress.
Treatment
What does that mean for your treatment
No STK38-specific treatment or management approach is currently established for people with a pathogenic or loss-of-function variant in the STK38 gene. The STK38 gene is being studied in early cancer research as a possible biomarker and drug target, but this has not yet changed routine care.
Gene function
What if the gene works
Your cells use the STK38 gene to keep growth, division, and cleanup tasks well organized. It supports signal pathways that help cells respond to everyday demands and maintain their structure. Understanding how the STK38 gene works in the body helps explain how cells stay balanced over time.
STK38 helps pass signals inside cells by adding small chemical tags to selected proteins. These signals coordinate everyday tasks such as growth, movement, and survival.
It supports the cell cycle, the step by step process cells use to grow and divide. This helps cells renew in an orderly way and time division carefully.
STK38 helps organize parts of the cell that guide shape, position, and movement. It also supports structures that help prepare cells for division.
This gene supports autophagy (the cell’s recycling system), which breaks down worn cell parts and reuses their building blocks. That helps cells adapt to normal changes in energy demand and daily wear.
What is a variant?
A genetic variant is a minor change in the DNA code within a gene. These changes are common and help explain normal differences between people, including appearance, metabolism, and how the body reacts to environmental influences. Many variants do not cause any noticeable effect and are simply part of natural genetic diversity. 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 STK38 gene can change the shape or amount of the STK38 protein, which may weaken its kinase activity or disrupt how it interacts with other proteins. How STK38 gene variants affect protein function depends on the change itself: milder variants may partly reduce activity or stability, while more severe variants can greatly lower protein levels or prevent activation. Some variants may also alter where the protein is located inside the cell, which can disturb signaling and cell-cycle control.
How variants are linked to conditions
Variants in the STK38 gene do not yet have a broadly confirmed link to a specific health condition, although research on possible STK38 gene variants linked to conditions is still evolving. If you have a confirmed variant in the STK38 gene, your doctor or genetic counselor can explain what it may mean in the context of your personal and family history.
A variant is not necessarily a diagnosis
Genetic variants are common across the general population and are a 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 definite diagnosis, particularly when several genes and environmental factors play a role. In other cases, though, 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 is not yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the STK38 gene. If testing has found a change in STK38, a doctor or genetic counselor can help explain what that result may mean for your personal and family risk.
Inheritance of STK38 variants
There is not yet a broadly confirmed disease specific inheritance pattern for the STK38 gene, so the answer to how STK38 gene variants are inherited is still being clarified as research develops. The STK38 gene is located on chromosome 6, which is an autosome. That means each person usually inherits one copy of the STK38 gene from each parent, regardless of sex.
What does my STK38 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific condition for STK38. If you have a specific STK38 result and want to understand what it could mean for your relatives, 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
Genetic testing for STK38 variants usually uses a blood or saliva sample to read the STK38 gene and look for changes in its DNA code. This is how you find out about variants in the STK38 gene: a lab compares your sequence with a reference and classifies any change as likely benign, potentially health related, or uncertain.
When should I consider getting a genetic test?
There is not yet a broadly established STK38-specific reason for genetic testing in routine care. Testing decisions are usually based on your personal health and family history, ideally with a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic findings can provide useful insight, but how much they reveal depends on the condition and on the type of variant involved. Many other factors, including lifestyle, environment, age, and medical history, also shape how the body works over time. For some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is best considered alongside other parts of care. In other situations, a genetic result can offer a clear answer. In areas such as medication response, genetic results may help place individual experiences in context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small differences in DNA can change how the body breaks down a drug, moves it through the body, or responds to it at its target, so the same treatment may work better for some people than for others. This kind of variation is common and can influence how much benefit a person gets from a medication or how likely they are to notice side effects.
What is Pharmacogenetics?
Pharmacogenetics is the field of study that examines how genetic differences affect medication response. It looks at relationships between genes and drugs to better explain why the same treatment may work differently from one person to another. For many medicines, genes influence how strongly a drug works or how the body handles it. This information can support more informed and individualized treatment decisions. More detail on this topic is available in the LearnHub.
Drugs influenced by the STK38 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices. If you have questions about side effects, how well a treatment is working, or any other health concerns, talk with your doctor or pharmacist.
History
The STK38 gene entered the scientific literature in the 1990s, when researchers studying cell signaling identified it as part of the NDR family of protein kinase genes. It was also known as NDR1 in early research papers, reflecting how scientists first grouped it with closely related genes before naming became more standardized. From these first observations, research expanded steadily. Over time, studies in human cells and animal models helped place the STK38 gene within broader signaling networks that control how cells grow, divide, and respond to stress. Its history is mainly a research story rather than a public one, with interest growing through laboratory findings rather than a single widely known medical milestone.
