The NEMP1 gene helps support the membrane around the cell nucleus, the structure that stores your DNA. If the NEMP1 gene does not work properly, cells may have trouble keeping the nucleus stable, which can affect how some tissues grow and function. This gene plays an important role in normal development, and certain rare variants have been linked to problems with growth and reproduction.
What is a gene?
Genes are stretches of DNA that carry instructions cells use to make molecules or to regulate processes throughout the body. Some genes provide the directions for producing proteins, which are the active parts of cells. Others mainly direct when certain processes happen, where they take place, and how much activity there is. Taken together, genes affect how the body develops and works, and they can influence your response to food, stress, or medications.

Overview
NEMP1Gene function
What if the gene works
The NEMP1 gene makes a protein in the membrane around the cell nucleus. It helps support nuclear shape and stability, especially in developing reproductive cells.
Risk
What if the gene does not work
Milder to more severe variants in the NEMP1 gene can reduce how well cells maintain the nuclear envelope, the membrane around the nucleus. This may alter nuclear shape and weaken the protein network that supports normal cell function.
Treatment
What does that mean for your treatment
No NEMP1-specific treatment or management approach is currently established for pathogenic variants in the NEMP1 gene. Care is guided by a person’s symptoms and clinical findings, while NEMP1 is mainly being studied in basic research rather than used to choose medicines.
Gene function
What if the gene works
Your cells need the nucleus to stay steady because it stores DNA and helps direct everyday cell activity. The NEMP1 gene makes a protein that sits in the membrane around the nucleus and supports its structure from the inside. Understanding how the NEMP1 gene supports the membrane around the nucleus helps explain how cells keep their shape during daily strain.
The NEMP1 gene helps maintain the shape of the nucleus, the part of the cell that stores DNA. Its protein sits on the inner side of the nuclear envelope and supports a smooth, stable outline during normal cell activity.
NEMP1 works with other proteins at the nuclear envelope to reinforce the membrane around the nucleus. This support helps cells handle routine physical forces during movement, stretching, and growth.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, or how the body responds to environmental influences. Many variants do not have any noticeable effect and simply represent natural genetic variation. In some cases, though, a variant can change the function of a gene more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the NEMP1 gene can alter how the NEMP1 protein is made, folded, or positioned in the membrane around the cell’s nucleus. How variants in the NEMP1 gene affect protein function often depends on the type of change: milder variants may leave some activity, while more disruptive variants can greatly reduce protein stability, membrane insertion, or binding to nearby proteins. Variants that stop protein production early may leave little or no working protein at the membrane around the nucleus.
How variants are linked to conditions
Pathogenic variants in the NEMP1 gene can cause primary ovarian insufficiency, a condition in which ovarian function declines earlier than expected and menstrual periods may stop before age 40. Research on the NEMP1 gene and primary ovarian insufficiency is strongest when a person inherits two nonworking copies. Common variants near the NEMP1 gene have also been linked to modest differences in menopause timing across populations, but these do not predict one person's fertility.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are common throughout 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 indicates a possible link rather than a definite diagnosis, especially when multiple genes and environmental factors also play a role. In some situations, 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 NEMP1 gene. Anyone with concerns about their personal or family risk can speak with a doctor or genetic counselor.
Inheritance of NEMP1 variants
There is not yet a broadly confirmed, disease-specific Mendelian pattern for how NEMP1 gene variants are inherited, so the answer to how NEMP1 gene variants are inherited is still developing as research grows. The NEMP1 gene is located on chromosome 1, which is an autosome. That means each person inherits one copy of the NEMP1 gene from their mother and one copy from their father.
What does my NEMP1 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific condition for NEMP1, though this can become clearer as research grows. If you have a specific NEMP1 result and want to understand what it could mean for relatives, a doctor or genetic counselor can explain it in the context of your family history and the exact change found.
Genetic information
Genetic testing
How you find out about variants
Genetic testing for variants in the NEMP1 gene reads DNA from a blood, saliva, or cheek swab sample. It can show whether a variant is present and whether it is considered benign, uncertain, or linked to a diagnosed genetic condition.
When should I consider getting a genetic test?
NEMP1 testing is not part of routine care for most people. Testing decisions are usually based on your health history, symptoms, and family history, ideally with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can be informative, but what it can tell you varies with 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 most useful when viewed alongside other parts of care. In other situations, a genetic result can give a clear answer. In areas like medication response, genetic results can help put a person’s 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 is a common reason why the same medication 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 genes can affect a person’s response to medications. It focuses on gene and drug patterns to help explain why the same treatment may work differently from one person to another. For many medicines, genes influence both how the body processes a drug and how strong its effects may be. This information can support more informed and more individualized treatment decisions.

Drugs influenced by the NEMP1 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choices, so any concerns about side effects, new symptoms, or how a medicine may affect you are best discussed with your doctor.
