The NOXRED1 gene helps retinal cells carry out important chemical reactions that support vision. This gene plays an important role in helping the light sensing tissue at the back of the eye keep working over time. When both copies do not work properly because of rare inherited variants, this can cause retinitis pigmentosa, often leading to night blindness and a gradual loss of side vision. NOXRED1 has not become a high profile gene in popular culture.
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, which do much of the cell’s work. Other genes are used mainly to control when certain activities happen, where they happen, and how active they are. Together, genes affect how the body develops and works, and they can also influence how you respond to food, stress, or medications. For a deeper look at this topic, you can find more in LearnHub.
Overview
NOXRED1Gene function
What if the gene works
The NOXRED1 gene helps cells carry out oxidation reduction reactions, which are small chemical steps that move electrons. This supports normal energy use and everyday cell function.
Risk
What if the gene does not work
Milder to more severe variants in the NOXRED1 gene can reduce its oxidoreductase activity (its role in moving electrons during chemical reactions) to different degrees, which may disturb cells' chemical balance.
Treatment
What does that mean for your treatment
No NOXRED1-specific treatment or management approach is currently established, so care is guided by your symptoms and overall clinical picture rather than by a drug choice tied to the NOXRED1 gene.
Gene function
What if the gene works
Cells use the NOXRED1 gene to help make cholesterol, a fat-like substance found in every cell membrane. Its protein supports a step in the sterol pathway, the set of reactions that leads to cholesterol. This steady cholesterol supply helps cells build membranes and carry out routine signaling.
The NOXRED1 gene helps cells complete part of the chemical pathway that produces cholesterol. When this process runs smoothly, cells can keep a steady supply of cholesterol for everyday needs.
By supporting normal cholesterol production, this gene helps cells build and maintain healthy membranes. These membranes need the right balance of structure and flexibility so cells can send signals and move materials in and out.
What is a variant?
A genetic variant is a small difference in the DNA sequence within a gene. These differences are common and help shape normal human diversity, including variation in appearance, metabolism, or how the body responds to environmental influences. Many variants do not cause any noticeable effect and are simply part of natural genetic variation. In some situations, though, a variant can change how a gene functions more significantly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Changes in the NOXRED1 gene can alter how much protein a cell makes or how well the protein folds, stays stable, and works inside the cell. Milder variants may leave some activity in place, while more severe variants can sharply reduce protein levels or create a shortened protein that cannot interact normally with other cell components. This is how NOXRED1 gene variants affect function at the cellular level.
How variants are linked to conditions
Pathogenic variants in the NOXRED1 gene are linked to a rare inherited mitochondrial condition called complex I deficiency. In some people, NOXRED1 gene variants linked to conditions can include Leigh syndrome or a Leigh-like illness, often with developmental delay, low muscle tone, seizures, feeding difficulties, and episodes of high lactate levels. This is usually an autosomal recessive condition, so a diagnosis is typically confirmed when a person has two disease-causing variants in the NOXRED1 gene.
A variant is not necessarily a diagnosis
Genetic variants are a usual part of human biology and are found throughout the general population. Most do not have a direct effect on health and instead reflect normal 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 play a role. In some situations, though, a single well-characterized variant in a particular 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 lifestyle or environmental factors that increase or reduce health risks related to the NOXRED1 gene. For many, personal risk is shaped more by whether a harmful change in NOXRED1 runs in the family and whether both copies of the gene are affected.
Inheritance of NOXRED1 variants
There is not yet a broadly confirmed disease specific inheritance pattern for the NOXRED1 gene, so how NOXRED1 gene variants are inherited in relation to a defined genetic condition is still being clarified. NOXRED1 is located on chromosome 14, which is an autosome. That means you inherit one copy of the NOXRED1 gene from your mother and one copy from your father.
What does my NOXRED1 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific, well-established condition for NOXRED1 in routine patient care, though this can become clearer as research grows. If you have a NOXRED1 result and want to know what it could mean for close 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 find out whether you carry a variant in the NOXRED1 gene, genetic testing for NOXRED1 variants analyzes DNA from blood, saliva, or a cheek swab. A lab reads the gene's sequence, looks for changes, and reports whether a variant was found and how it is classified.
When should I consider getting a genetic test?
There is not yet a broadly established, NOXRED1-specific reason for genetic testing in routine care. Testing decisions are usually based on your personal health history, symptoms, and family history, together with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic finding can provide useful insight, but how much it explains varies based on the condition and the type of variant involved. Many other factors, including lifestyle, environment, age, and medical history, also shape how the body works over time. For some conditions, especially those influenced 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 such as medication response, genetic information 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. Small differences in genes can change how the body breaks down a drug, moves it through the body, or responds to it at its target. This helps explain why the same medication may work well for one person, work less well for another, or cause more side effects in someone else. These differences are common and are one reason treatment response can vary from person to person.
What is Pharmacogenetics?
Pharmacogenetics is the area of study that examines how genetic differences affect responses to medications. It focuses on connections between genes and drugs to help explain why the same treatment can work differently from one person to another. With many medicines, genes influence both how strongly a drug works and how the body handles it. This understanding can support treatment decisions that are more informed and more personalized.

Drugs influenced by the NOXRED1 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication choice or dose, so general questions about medicines, side effects, or your health are best discussed with your doctor. Seek medical advice if a medicine is causing new symptoms, not helping as expected, or if you are worried about how it fits with your overall health.
