The TEX44 gene is active mainly in the testes and helps sperm develop normally. If it does not work properly, sperm production and sperm shape can be affected, which may reduce fertility. People with pathogenic variants in the TEX44 gene may have very low sperm counts or sperm that do not move well enough to reach and fertilize an egg. This gene is mainly discussed in fertility medicine rather than in everyday health news.
What is a gene?
A gene is a stretch of DNA that carries instructions your cells use to make molecules or direct processes in the body. Some genes hold the information needed to produce proteins, the parts of cells that do much of the work. Others mainly help regulate when certain processes happen, where they happen, and how strongly they take place. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications.

Overview
TEX44Gene function
What if the gene works
The TEX44 gene is active mainly in the testes and helps support sperm development. It appears to play a part during meiosis, the cell division step that makes sperm.
Risk
What if the gene does not work
Milder variants in the TEX44 gene may partly lower TEX44 protein activity, while more severe variants can greatly reduce or stop protein production. This changes how much working TEX44 protein cells can make, mainly in the testis.
Treatment
What does that mean for your treatment
No TEX44-specific treatment or management approach is currently established. Care is based on the person’s clinical fertility findings rather than on a pathogenic variant in the TEX44 gene itself. The TEX44 gene is being studied as a candidate gene in male infertility research, but this has not yet changed guideline-based drug choices or treatment.
Gene function
What if the gene works
In the testis, the TEX44 gene is active during the stepwise process that makes sperm. Its activity is linked to the special cell divisions that shape early sperm cells into mature ones. Understanding what the TEX44 gene does during sperm development helps place it within normal male fertility biology.
The TEX44 gene is active in developing sperm cells as they move through the stages of sperm production. This supports the normal progression from early germ cells to more mature sperm cells.
This gene is linked to the tightly organized cell divisions that create sperm cells with half the usual amount of DNA. That step is a normal part of making sperm for reproduction.
What is a variant?
A genetic variant is a minor difference in the DNA sequence within a gene. These differences are common and help shape normal human diversity, including variations in appearance, metabolism, and the way the body responds to environmental influences. Many have no noticeable effect and are simply part of 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 TEX44 gene may change the protein’s shape, stability, or the amount a cell can make. More disruptive variants can lead to a shortened protein or no usable protein at all, while milder variants may only partly reduce function or weaken how the protein interacts with other cell components. This range helps explain how TEX44 gene variants affect protein function at the cellular level.
How variants are linked to conditions
Current evidence on how TEX44 gene variants are linked to conditions is still developing. Variants in the TEX44 gene do not yet have a broadly confirmed link to a specific health condition, and any confirmed TEX44-related diagnosis should be interpreted with a doctor or genetic counselor.
A variant is not necessarily a diagnosis
Variants in genes are a usual part of human biology and are widespread in the general population. Most do not directly affect health and simply reflect natural human variation. For many genes, having a variant associated with a condition suggests a possible link rather than a definite diagnosis, especially when several genes and environmental factors also contribute. In some situations, though, a single well-characterized variant in a particular 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 TEX44 gene. If a change in TEX44 is found on genetic testing, a doctor or genetic counselor can help explain what it may mean for your personal and family risk.
Inheritance of TEX44 variants
There is not yet a broadly confirmed Mendelian pattern for how TEX44 gene variants are inherited in a specific TEX44 related condition, so the answer to how TEX44 variants are inherited remains cautious and may change as research develops. The TEX44 gene is located on chromosome 11, which is an autosome. That means you inherit one copy of the TEX44 gene from your mother and one copy from your father.
What does my TEX44 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific TEX44-related condition for families to use in a clear, routine way. If you have a TEX44 result and want to understand what it could mean for 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
To look for changes in the TEX44 gene, genetic testing for TEX44 variants uses DNA from blood, saliva, or a cheek swab. A laboratory reads the gene's sequence and compares it with the usual pattern. Results show whether a variant was found and how it is classified.
When should I consider getting a genetic test?
There isn't yet a broadly established, TEX44-specific clinical reason for testing in routine care. Testing decisions are usually made with a doctor or genetic counselor based on fertility concerns, other health findings, and family history.
A genetic result is only one part of your health story
Genetic findings can provide meaningful insight, but how much they explain depends on the condition and the type of variant involved. Many factors, including lifestyle, environment, age, and medical history, influence how the body works over time. For some conditions, especially those shaped by many genes, genetic information provides context rather than certainty and is best understood alongside other parts of care. In other situations, a genetic result can offer 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. This helps explain why the same treatment may work well for one person, do little for another, or cause more side effects in someone else. Part of the reason is that inherited differences can change how the body breaks down, transports, or responds to a drug, which can influence both benefit and sensitivity.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in a person’s genes can shape their response to medicines. It focuses on links between genes and drugs to help explain why the same treatment may work differently in different people. With many medications, genes can influence how powerfully a drug works or how the body handles it. Understanding this can support treatment decisions that are better informed and more individualized.

Drugs influenced by the TEX44 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in how medicines work, so questions about side effects, new symptoms, or changes to treatment are best discussed with your doctor.
