The NOMO1 gene helps control very early embryo signals that guide body patterning, including which side certain organs develop on. If it does not work properly, development may not follow the usual plan, which can contribute to differences present from birth, such as unusual organ placement or related heart and organ formation changes. This gene plays an important role in keeping these early growth signals balanced.
What is a gene?
Genes are stretches of DNA that carry instructions your cells use to make molecules or regulate activities in the body. Some genes provide the code for proteins, the parts of cells that do much of the work. Other genes mainly guide when certain processes happen, where they occur, and how active they are. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, and medications.

Overview
NOMO1Gene function
What if the gene works
The NOMO1 gene helps guide very early body development. It supports signals that help an embryo form a normal left-right body plan and place organs in their usual pattern.
Risk
What if the gene does not work
Changes in the NOMO1 gene can weaken or disrupt a protein complex that helps control early cell signaling and shapes the endoplasmic reticulum, a membrane network inside cells. Milder and more severe variants can reduce this control to different degrees.
Treatment
What does that mean for your treatment
No treatment or management approach specific to the NOMO1 gene is currently established. The NOMO1 gene is being studied as a possible biomarker in some cancers, especially colorectal cancer, but this has not changed routine drug choices.
Gene function
What if the gene works
Early in development, NOMO1 helps cells respond to signals that shape the body’s basic layout. It also supports routine work in the endoplasmic reticulum, the cell compartment that folds and moves proteins. When this gene is working properly, these steps stay coordinated and steady.
NOMO1 helps tune NODAL signaling, a pathway that guides early embryo patterning. This supports orderly decisions about body layout, including left-right body patterning during early development.
Inside the endoplasmic reticulum (the cell area that folds and processes proteins), NOMO1 works with NCLN and TMEM147. Together, they help keep this compartment organized while proteins are being handled.
What is a variant?
Small changes within a gene’s DNA sequence are known as genetic variants. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, and the way the body responds to environmental influences. A large number of variants have no noticeable effect and simply reflect natural genetic variation. Sometimes, though, a variant can have a bigger effect on how a gene works and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Different variants in the NOMO1 gene can change the protein’s shape, stability, or the amount a cell makes. Milder variants may partly weaken how the protein folds or links with partner proteins, while more severe variants, including changes that create a shortened protein, can greatly reduce the protein or stop it from working. This helps explain how variants in the NOMO1 gene affect protein function and cell signaling.
How variants are linked to conditions
The NOMO1 gene does not yet have a broadly confirmed link to a specific health condition, though research on NOMO1 gene variants and health conditions is still developing. If you have a confirmed variant in the NOMO1 gene, your doctor or genetic counselor can explain what it may mean in the context of your personal and family history.
A variant is not necessarily a diagnosis
Variants are a routine part of human biology and are common throughout the general population. Most do not have a direct effect on health and instead represent natural human diversity. For many genes, carrying a variant linked with a condition indicates a possible association 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 increase or reduce health risk related to the NOMO1 gene. Anyone with concerns about personal or family risk can speak with a doctor or genetic counselor.
Inheritance of NOMO1 variants
There is not yet a broadly confirmed Mendelian inheritance pattern for conditions linked specifically to the NOMO1 gene, so how NOMO1 gene variants are inherited in relation to disease is still being clarified. The NOMO1 gene is located on chromosome 16, which is an autosome, so each person inherits one copy from each parent. In general, that means a change in this gene can be passed down through either side of the family.
What does my NOMO1 result mean for my family?
There is not yet a broadly confirmed inherited pattern tied to a specific health condition for the NOMO1 gene, so a NOMO1 result does not currently give clear, standard answers about risk for relatives. As research grows, this understanding may change. If you have a specific NOMO1 result, a genetics specialist can explain what it may mean for your family in the context of your personal and family history.
Genetic information
Genetic testing
How you find out about variants
To find out whether you carry a variant in the NOMO1 gene, genetic testing usually looks at DNA from a blood sample or cheek swab. This is how genetic testing works for the NOMO1 gene: a lab reads the gene’s sequence and compares it with known patterns. Results may show a benign variant, a variant of uncertain significance, or a variant linked to a genetic condition.
When should I consider getting a genetic test?
There is not yet a broadly established NOMO1-specific reason for genetic testing in routine care. Decisions about testing are usually made with a doctor or genetic counselor based on your health history, family history, and the reason genetic testing is being considered.
A genetic result is only one part of your health story
A genetic result can give helpful insight, but how much it reveals depends on the condition and the type of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, also shape how the body functions. For some conditions, especially those influenced by many genes, genetic information provides context rather than certainty and is best understood together with 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 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 sensitive to side effects. Part of the reason is that inherited differences can change how the body breaks down, moves, or responds to a drug, which can influence how strongly it works.
What is Pharmacogenetics?
Pharmacogenetics studies how genetic differences shape a person’s response to medications. It examines relationships between genes and drugs to help explain why the same treatment may work differently from one person to another. With many medicines, genes can affect how strongly a drug works or how the body processes it. This information can support more informed, more individualized treatment decisions.

Drugs influenced by the NOMO1 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 medicines, side effects, or your general health are best discussed with your doctor or pharmacist.
