The TEX22 gene is mainly active in the testes, where it helps support normal sperm development. This gene plays an important role in how sperm cells mature, so if it does not work properly, sperm production may be reduced or disrupted. Variants in the TEX22 gene have been linked to some cases of male infertility, especially when a person has trouble making enough healthy sperm.
What is a gene?
Genes are sections of DNA that hold instructions your cells use to make molecules or manage processes throughout the body. Some genes carry the code for making proteins, which are the working parts of cells. Other genes mostly help direct when certain processes happen, where they happen, and how strongly they occur. Together, genes affect how the body develops and works, and they can also influence how you respond to food, stress, and medications.

Overview
TEX22Gene function
What if the gene works
The TEX22 gene is mainly active in the testes and is thought to help sperm develop. It appears to play a role as germ cells divide and mature into sperm.
Risk
What if the gene does not work
Changes in the TEX22 gene may reduce production of the TEX22 protein or change its structure in testis cells. Milder variants may leave some function intact, while more severe variants can interfere more with its normal cellular role.
Treatment
What does that mean for your treatment
No treatment or drug choice is currently guided specifically by pathogenic or loss-of-function variants in the TEX22 gene, and no TEX22-specific management approach is established in clinical guidelines.
Gene function
What if the gene works
In adults, the TEX22 gene is mainly active in the testis, where sperm cells are made. It supports normal sperm development in the testis and helps this tissue carry out routine reproductive cell activity. Understanding its usual role helps connect the gene to day to day male reproductive function.
In the testis, the TEX22 gene is active in cells that are developing into sperm. Its usual role supports the orderly steps of sperm development that help maintain normal male fertility.
As reproductive cells mature, the TEX22 gene helps those cells move through their normal development program. This supports healthy testis function during ongoing sperm production.
What is a variant?
A genetic variant is a minor change in the DNA sequence within a gene. These changes are common and help shape normal differences among people, such as appearance, metabolism, or how the body responds to environmental influences. Many variants do not have any noticeable effect and are simply part of natural genetic variation. In some situations, though, a variant can change how a gene functions more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the TEX22 gene can change how much protein a cell makes or alter the protein's shape, stability, or interactions with other molecules in the cell. In simple terms, this is how TEX22 gene variants affect protein function at the cellular level. Milder variants may only partly reduce protein activity, while more severe variants can greatly disrupt the protein or stop it from being made.
How variants are linked to conditions
Current evidence on the TEX22 gene and health conditions is still developing. The TEX22 gene does not yet have a broadly confirmed link to a specific medical condition, and anyone with a confirmed TEX22-related diagnosis should rely on guidance from their doctor or genetic counselor rather than general information.
A variant is not necessarily a diagnosis
Genetic variants are a routine part of being human and are widely found in the general population. Most do not directly affect health and instead reflect normal human variation. For many genes, having a variant associated with a condition points to a possible link rather than a confirmed diagnosis, especially when several genes and environmental factors also play a role. 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 TEX22 gene. If a change in TEX22 has been found in you or your family, a doctor or genetic counselor can help explain what that result may mean in the context of your personal and family history.
Inheritance of TEX22 variants
Current evidence on the inheritance of TEX22 gene variants does not yet support one broadly confirmed disease associated pattern, such as autosomal dominant or autosomal recessive. This can change as research develops. The TEX22 gene is located on an autosome, which means you inherit one copy from each parent. Because of that location, inheritance of TEX22 gene variants would not be expected to differ between males and females in the same way it can for genes on the X or Y chromosome.
What does my TEX22 result mean for my family?
There isn’t yet a broadly confirmed inheritance pattern tied to a specific health condition for TEX22, though this understanding can change as research develops. If you have a specific TEX22 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
Genetic testing for TEX22 variants uses DNA from a blood, saliva, or cheek swab sample to read the TEX22 gene and look for changes in its code. Testing may be done in a multigene panel or broader sequencing, and results are usually classified as benign, uncertain, or clinically relevant.
When should I consider getting a genetic test?
There isn't yet a broadly established, TEX22-specific clinical reason for testing. Testing decisions are best made with a doctor or genetic counselor, based on your symptoms, fertility concerns, 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 kind of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, influence how the body works. For some conditions, especially those shaped by many genes, genetic information offers context rather than certainty and is best considered alongside other parts of care. In other situations, a genetic result can give a clear answer. In areas like medication response, genetic results can also 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 DNA can change how the body breaks down a drug, moves it through the body, or responds to it at its target. This helps explain why the same treatment may work well for one person, work less well for another, or cause more side effects in someone who is more sensitive to it.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in a person’s genes can affect the way they respond to medicines. By studying links between genes and medications, it helps explain why the same treatment may work differently in different people. For many drugs, genes influence how strongly the medicine works and how the body processes it. This information can support treatment choices that are more informed and more individualized. More on this topic is available in the LearnHub.
Drugs influenced by the TEX22 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding how medicines are used, so general concerns about your health, treatment, or side effects are best discussed with your doctor.
