The DHRS13 gene belongs to a family of genes that make enzymes used in everyday cell chemistry. This gene helps your body process small molecules that cells use to keep normal functions running smoothly. If the DHRS13 gene does not work as expected, some of these chemical steps may be less efficient, which can change how cells handle certain substances. DHRS13 is not a gene that has become widely known in popular culture, and it is mainly discussed in genetics and laboratory research.
What is a gene?
Genes are sections of DNA that give your cells instructions for making molecules or managing processes in the body. Some genes carry the directions for producing proteins, the parts of cells that do the work. Other genes mostly regulate when certain processes happen, where they take place, and how strongly they operate. As a group, genes affect how the body develops and functions, and they can also influence how you respond to food, stress, or medications.

Overview
DHRS13Gene function
What if the gene works
The DHRS13 gene makes an enzyme that likely helps cells handle small molecules through routine chemical reactions. It belongs to a larger family of enzymes involved in everyday cell chemistry.
Risk
What if the gene does not work
Variants in the DHRS13 gene may change how much DHRS13 protein a cell makes or how well it works. Milder variants may leave some activity, while more severe variants can greatly reduce or abolish it.
Treatment
What does that mean for your treatment
No DHRS13-specific treatment, management approach, or drug choice is currently established in clinical guidelines for people with a pathogenic or loss-of-function variant in the DHRS13 gene.
Gene function
What if the gene works
Inside your cells, the DHRS13 gene helps make an enzyme for routine chemical work. In simple terms, DHRS13 gene function is tied to oxidation reduction reactions, which are small chemical changes cells use to process substances and keep metabolism moving. When this gene is working as expected, these steps can happen in a steady, organized way.
The DHRS13 gene helps cells carry out oxidation reduction reactions, which are small chemical swaps used to change one molecule into another. These reactions are part of normal metabolism and help cells manage everyday chemical tasks.
Its protein acts as an enzyme, meaning it helps certain reactions happen at the right time and pace. This supports smooth handling of small molecules inside cells and contributes to normal cell activity.
What is a variant?
A genetic variant is a slight change in the DNA sequence within a gene. These changes are common and help shape normal human diversity, such as differences in appearance, metabolism, or the way the body responds to environmental influences. Many do not have any noticeable effect and simply reflect natural genetic variation. In some cases, though, a variant can more substantially change how a gene functions and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
How DHRS13 gene variants affect protein function depends on the type of DNA change. Variants in the DHRS13 gene may alter the protein’s shape, stability, or ability to bind its usual chemical partners, which can lower or disrupt its enzyme activity inside cells. Milder variants may leave some activity, while more disruptive variants can greatly reduce the amount of protein made or lead to a shortened protein that is cleared more quickly.
How variants are linked to conditions
Current evidence on how DHRS13 gene variants are linked to conditions is still limited, and the DHRS13 gene does not yet have a broadly confirmed connection to a specific health condition. If you have a reported change in the DHRS13 gene, your doctor or genetic counselor can interpret it in the context of your personal and family history.
A variant is not necessarily a diagnosis
Genetic variants are a normal feature of human biology and are common in the general population. Most do not have a direct effect on health and simply reflect natural human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a confirmed diagnosis, especially when multiple genes and environmental factors also play a role. In some 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 DHRS13 gene. Anyone with questions about personal or family risk can talk with a doctor or genetic counselor.
Inheritance of DHRS13 variants
There is not yet a broadly confirmed Mendelian pattern for the inheritance of the DHRS13 gene variants in relation to a specific human condition, so a single mode such as autosomal dominant or autosomal recessive is not currently used for this gene. In practical terms, discussions of DHRS13 inheritance stay cautious because research is still developing. DHRS13 is located on an autosome, which means you inherit two copies of the DHRS13 gene, one from each parent.
What does my DHRS13 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for DHRS13, though this can change as research develops. If you have a DHRS13 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 and the exact result.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for variants in the DHRS13 gene usually uses a blood or saliva sample. A lab reads the gene's DNA sequence, compares it with a reference sequence, and classifies any variant using current medical evidence.
When should I consider getting a genetic test?
There is not yet a broadly established, DHRS13-specific reason for genetic testing in routine care. Decisions about testing 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
A genetic finding can provide meaningful insight, but how much it reveals depends on the condition and on the type of variant involved. Many factors, including lifestyle, environment, age, and medical history, shape how the body functions over time. In some conditions, especially those influenced by many genes, genetic information adds 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 help put individual experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Small differences in genes can change how the body breaks down a drug, moves it through the bloodstream, or responds to it at its target, so the same treatment may work better for one person than another. This is a common part of human biology and can influence how much benefit someone gets from a medicine or how sensitive they are to side effects.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can shape a person’s response to medications. It looks at links between genes and drugs to help explain why the same treatment can work differently from one person to another. For many medicines, genes affect both how the body processes a drug and how strong its effects may be. This information can support more informed, individualized treatment decisions.

Drugs influenced by the DHRS13 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices, so general questions about side effects, new symptoms, or how medicines may affect you are best discussed with your doctor.
