The REC114 gene helps egg and sperm cells form by starting a normal step where DNA is exchanged as these cells mature. This gene plays an important role in fertility, and if it does not work properly, some people may have difficulty making healthy sperm or eggs and may face infertility. REC114 is mainly discussed in reproductive genetics and fertility research rather than in popular culture. It has not become a widely recognized public gene.
What is a gene?
Genes are sections of DNA that provide cells with instructions to make molecules or regulate processes in the body. Some genes carry the information needed to produce proteins, the parts of cells that do much of the work. Other genes are mainly involved in controlling when certain processes take place, where they occur, and how strongly they operate. Together, genes affect how the body develops and functions, and they can also shape how you respond to food, stress, or medications.

Overview
REC114Gene function
What if the gene works
The REC114 gene helps sperm and egg cells make small, planned DNA breaks needed to swap genetic material during meiosis. This supports normal chromosome pairing and fertility.
Risk
What if the gene does not work
Variants in the REC114 gene are linked to infertility, including absent sperm production and, in some women, premature ovarian insufficiency. Milder or more severe variants can influence when problems appear and how strongly fertility is affected.
Treatment
What does that mean for your treatment
No REC114-specific treatment or drug selection approach is currently established for people with a pathogenic variant in the REC114 gene. Care is based on the person’s symptoms and reproductive needs rather than on a targeted medicine linked to this gene.
Gene function
What if the gene works
If you carry the REC114 gene, it is mainly active in cells that are making eggs or sperm. It supports meiosis, the special cell division that creates cells with half the usual number of chromosomes. Understanding how the REC114 gene works helps explain how chromosome pairs swap small pieces of DNA in a controlled way.
The REC114 gene helps start meiosis in developing egg and sperm cells. Its protein joins a small group of helpers that mark where the cell will begin a controlled DNA exchange process.
One of its main jobs is to help create carefully timed DNA breaks during meiosis. These temporary cuts are a normal step that lets paired chromosomes begin swapping matching pieces of DNA.
By helping start DNA exchange, the REC114 gene supports close pairing between matching chromosome pairs. This gives the cell a way to reshuffle genetic information while keeping chromosome numbers on track for eggs and sperm.
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 traits such as appearance, metabolism, and the way the body responds to environmental factors. Many do not cause any noticeable effect and are simply part of natural genetic variation. In some situations, however, 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 REC114 gene can lower how much REC114 protein a cell makes, make the protein less stable, or weaken its binding to partner proteins that help start meiosis. More disruptive variants may block these protein groups from assembling on chromosomes, while milder variants can leave some activity in place. This range helps explain how REC114 gene variants affect meiosis at the cellular level.
How variants are linked to conditions
Research on REC114 gene variants linked to conditions is still developing, and the REC114 gene does not yet have a broadly confirmed link to a specific health condition. As evidence grows, this picture may change, so anyone with a confirmed REC114-related finding should use guidance from their doctor or genetic counselor to understand what it may mean for them.
A variant is not necessarily a diagnosis
Variants in genes are a routine part of human biology and are widespread in the general population. Most do not directly affect health and instead reflect natural human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a certain diagnosis, especially when several genes and environmental factors are involved. In some situations, though, a single well understood 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 REC114 gene. If a REC114 change is found, personal risk often depends on the exact variant and family history, and a doctor or genetic counselor can help put that result in context.
Inheritance of REC114 variants
There is not yet a broadly confirmed, condition-specific Mendelian pattern for how REC114 gene variants are inherited, although this may become clearer as research grows. Current evidence links REC114 to human fertility in a limited number of families, so REC114 gene inheritance is not usually described with one firmly established pattern across all situations. The REC114 gene is located on chromosome 2, which is an autosome, so each person inherits one copy from each parent.
What does my REC114 result mean for my family?
Changes in the REC114 gene have been linked to inherited fertility conditions in a recessive pattern, which means close relatives may also be carriers even if they have no symptoms. For family members, this mostly matters for brothers, sisters, and future children, especially when planning a family. In some families, relatives may wish to learn whether they carry the same gene change.
Genetic information
Genetic testing
How you find out about variants
To look for variants in the REC114 gene, labs analyze DNA from a blood sample, saliva, or a cheek swab. Genetic testing for the REC114 gene usually uses sequencing, which reads the gene’s code and compares it with a reference sequence to identify changes. Results may show a benign variant, a variant of uncertain significance, or a pathogenic variant.
When should I consider getting a genetic test?
There isn't yet a broadly established, REC114-specific reason for genetic testing. Testing decisions are usually made with a doctor or genetic counselor based on your health history, fertility concerns, family history, and whether REC114 is included as part of a broader gene panel.
A genetic result is only one part of your health story
Genetic test results can be informative, but how much they reveal varies by the condition and the kind of variant involved. Over time, factors such as lifestyle, environment, age, and medical history also affect how the body works. For some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is most useful when considered alongside other parts of care. In other situations, a genetic result may offer a clear answer. In areas like medication response, genetic results can also help put personal experiences into perspective.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body responds to medicines. Some people break down a drug more quickly or more slowly than others, which can change how strongly it works or how likely side effects are. These differences are common and are one reason the same treatment can help one person more than another.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences can affect the way a person responds to medication. It looks at gene and drug patterns 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 processes it. This information can support treatment decisions that are more informed and more individualized.

Drugs influenced by the REC114 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in how medicines work, so general health or medication concerns are best discussed with your doctor. Seek medical advice if you develop unexpected side effects, your symptoms change after starting a treatment, or you have questions about whether a medicine is safe for you.
History
REC114 entered genetics research through studies of meiosis, the special cell division that makes eggs and sperm. In recent decades, knowledge has built on a long tradition of observing inherited traits. Researchers first characterized REC114 in model organisms such as budding yeast, where it was identified as one of the genes needed for the earliest steps of meiotic recombination. Building on this early work, scientists later found related versions of the REC114 gene in mammals, which showed that this part of reproduction is conserved across species. More recent human studies placed REC114 in the broader history of infertility research by linking rare, inherited variants to problems with egg or sperm formation.
