The NEK1 gene helps cells repair DNA, manage cell division, and maintain tiny cell structures that act like sensors. If it does not work properly, cells may cope with damage less well, which can contribute to some inherited conditions affecting bone growth and breathing, or increase the chance of nerve disease such as amyotrophic lateral sclerosis (ALS). Most people hear about the NEK1 gene through ALS research and genetic testing rather than from celebrity news.
What is a gene?
A gene is a section of DNA that holds instructions your cells use to make molecules or manage processes in the body. Some genes carry the directions for building proteins, which are the parts of cells that do the work. Others mainly help regulate when certain processes happen, where they happen, and how active they are. Taken together, genes affect how the body grows and works, and they can also influence how you respond to food, stress, or medicines.

Overview
NEK1Gene function
What if the gene works
The NEK1 gene helps cells repair DNA, divide in a controlled way, and maintain cilia, the tiny hairlike structures that help cells sense signals. These jobs support healthy nerve, kidney, and bone function.
Risk
What if the gene does not work
More severe variants in the NEK1 gene can cause a rare bone growth and chest development condition, sometimes with extra fingers or toes. Other variants can raise ALS risk. Effects may range from mild to severe.
Treatment
What does that mean for your treatment
For pathogenic variants in the NEK1 gene, no gene-specific treatment, management approach, or drug choice change is currently established. The NEK1 gene is being studied in amyotrophic lateral sclerosis and some cancers as a possible biomarker and future treatment target.
Conditions associated with NEK1
Gene function
What if the gene works
Your cells use the NEK1 gene during routine maintenance and repair. It helps coordinate DNA repair, orderly cell division, and the upkeep of tiny cell structures that act like sensors. Understanding how the NEK1 gene works in the body helps explain its role in everyday cell function.
The NEK1 gene helps cells detect DNA damage and organize repair steps. This supports accurate handling of genetic material as cells grow and renew themselves.
Its protein helps time key steps of cell division and supports the internal fibers that move chromosomes into place. This keeps the process orderly as one cell becomes two.
NEK1 also supports the building and maintenance of primary cilia, which are tiny antenna-like structures on many cells. These structures help cells sense signals from their surroundings and respond in a coordinated way.
What is a variant?
A genetic variant is a minor change in a gene’s DNA sequence. These changes are common and help shape normal differences between people, such as appearance, metabolism, or the way the body reacts to environmental influences. Many variants do not cause any noticeable effects and are simply part of natural genetic variation. In some situations, though, a variant can affect how a gene works to a greater extent and may contribute to or lead to a genetic condition.
Genetic variants
What if the gene does not work
Understanding how variants influence the NEK1 gene's function starts with the fact that many changes reduce the amount of usable NEK1 protein or alter its shape, making it less stable or less active in cells. More severe variants, especially those that create an early stop signal, can leave cells with little or no working protein. Milder variants may only partly disrupt protein interactions or cell repair. In established NEK1-related conditions, this range can influence which features appear and when.
How variants are linked to conditions
Pathogenic variants in the NEK1 gene are linked to two main health patterns. Certain inherited variants can cause short-rib thoracic dysplasia 6, a rare condition that affects bone growth and chest development. Some other NEK1 gene variants are associated with ALS risk in adults, but this reflects a higher chance of developing the condition rather than a certain diagnosis.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are common across the general population. Most variants do not directly affect health and simply reflect natural human diversity. For many genes, carrying a variant associated with a condition suggests a possible link rather than a definite diagnosis, especially when multiple genes and environmental factors are involved. In some situations, however, a single well-characterized variant in a specific gene can be 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 clearly increase or reduce health risk related to the NEK1 gene. Some changes in NEK1 are linked with a higher chance of certain neurologic conditions, but overall risk can still vary from one person or family to another.
Inheritance of NEK1 variants
The inheritance of NEK1-related conditions depends on the specific health problem and the variant involved. For the well-established skeletal condition linked to the NEK1 gene, the pattern is autosomal recessive, which means a child inherits one altered copy from each parent; when both parents are carriers, each pregnancy has a 25% chance of being affected. Some variants in the NEK1 gene are also linked to amyotrophic lateral sclerosis, but that association does not follow one simple inheritance pattern in the same clear way.
What does my NEK1 result mean for my family?
For the best-established condition linked to the NEK1 gene, family implications usually fit a recessive pattern. This often means parents are healthy carriers, brothers and sisters may also be carriers or, less often, have the condition, and other relatives may want to learn their carrier status when planning children. Some NEK1 changes are also linked to adult nerve disease risk, so family meaning can depend on the exact result.
Genetic information
Genetic testing
How you find out about variants
NEK1 genetic testing looks for variants in a blood, saliva, or cheek swab sample. A lab reads the DNA code in the NEK1 gene to check for changes, often as part of a multigene panel or broader sequencing test. Results may show a harmless variant, a disease-causing variant, or an unclear finding.
When should I consider getting a genetic test?
Consider testing for NEK1 if you or close relatives have ALS, a nerve disease that affects movement, especially if more than one family member is affected. It may also be considered in a baby or fetus with signs of a rare severe bone-growth condition linked to two changed NEK1 copies.
A genetic result is only one part of your health story
Genetic findings can offer useful insight, but how much they explain varies by the condition and the type of variant involved. How the body works over time is also shaped by many other factors, including lifestyle, environment, age, and medical history. For some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is most helpful when viewed alongside other parts of care. In other situations, a genetic result may 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. This helps explain why the same treatment works well for one person but less well for another, or why some people are more likely to have side effects. Small differences in how the body breaks down, moves, or responds to a drug are common and can influence both benefit and sensitivity to treatment.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences affect the way people respond to medications. It studies links between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medicines, genes 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 personalized. More detail on this topic is available in the LearnHub.
Drugs influenced by the NEK1 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in predicting medication response, so any concerns about side effects, changes in treatment, or how a medicine may affect you are best discussed with your doctor or pharmacist.
History
The NEK1 gene entered medical research through basic cell biology, when scientists identified it as part of a larger family of related genes in the 1990s. Initially understood only through visible traits, later recognized as tied to a specific gene, NEK1 drew more attention after animal studies linked changes in it to problems affecting movement and kidney development. From these first observations, research expanded steadily. Interest grew further when studies connected the NEK1 gene to inherited forms of amyotrophic lateral sclerosis, also called ALS. That finding made NEK1 part of a broader effort to understand why some families share a higher risk of this condition. Today, NEK1 is recognized as one of several genes that helped widen the picture of ALS genetics.
