The NAALADL1 gene gives instructions for a cell surface protein related to enzymes that process small protein pieces, which helps certain cells communicate. This gene plays an important role in cell signaling, so if it does not work as expected, some tissues may not behave in the usual, controlled way. Research has linked unusual NAALADL1 activity to prostate cancer biology, where higher activity in tumors has been associated with features linked to spread. It is mostly known in research and clinical settings rather than popular culture.
What is a gene?
A gene is a stretch of DNA that holds instructions your cells use to make molecules or regulate processes in the body. Some genes provide the directions for producing proteins, the parts of cells that carry out much of their work. Others mainly guide when certain processes happen, where they happen, and how strongly they are turned on. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medicines. To go into this topic in more detail, you can find more in the LearnHub.
Overview
NAALADL1Gene function
What if the gene works
The NAALADL1 gene helps make a cell surface protein related to enzymes that trim small protein pieces. This protein may support cell signaling and normal tissue development.
Risk
What if the gene does not work
Changes in the NAALADL1 gene may alter how its cell surface peptidase like protein folds or works. Milder variants can partly reduce protein activity, while more severe variants may leave cells with little or no normal NAALADL1 function.
Treatment
What does that mean for your treatment
No NAALADL1-specific treatment or management approach is currently established for people with a pathogenic variant in the NAALADL1 gene. NAALADL1 is being studied mainly as a possible biomarker in prostate cancer and other tumors, rather than as a guide to current drug choice.
Gene function
What if the gene works
Understanding NAALADL1 gene function helps explain how cells manage proteins at their surface. The NAALADL1 gene provides instructions for a protein attached to the cell membrane, where it can interact with nearby molecules. It belongs to a family of proteins involved in handling small protein fragments called peptides.
The NAALADL1 protein is positioned in the cell membrane. This placement lets it work where the cell meets its surroundings and where many signaling and processing steps begin.
Its protein is built like enzymes that act on small protein pieces called peptides. This supports a role in processing molecules near the outside of the cell.
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, such as 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 affect how a gene functions more substantially and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Variants in the NAALADL1 gene may change how much NAALADL1 protein a cell makes or whether the protein folds properly. In how NAALADL1 gene variants affect function, milder single-letter changes may slightly alter protein stability or interactions, while more severe variants that stop the gene from working can shorten the protein or greatly reduce how much of it is made. Many changes may have little or no measurable cellular effect.
How variants are linked to conditions
Variants in the NAALADL1 gene do not yet have a broadly confirmed link to a specific health condition, although research on NAALADL1 gene variants and disease is still developing. If you have a confirmed result involving the NAALADL1 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
Gene variants are a normal feature of human biology and are common across the general population. Most have no direct impact 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 cases, however, 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 NAALADL1 gene. If you have a NAALADL1 result and want to understand what it may mean for you or your family, speaking with a doctor or genetic counselor can help put it in context.
Inheritance of NAALADL1 variants
There is not yet a broadly confirmed Mendelian pattern for NAALADL1 gene inheritance tied to a specific human condition, so it is not described as clearly autosomal dominant, autosomal recessive, or X linked. As research evolves, that picture may become clearer. The NAALADL1 gene is located on chromosome 11, which is an autosome, so each person inherits one copy from each parent.
What does my NAALADL1 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific medical condition for NAALADL1, though this can change as research grows. If you have a NAALADL1 result and want to understand what it could mean for 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 look for changes in the NAALADL1 gene, NAALADL1 genetic testing uses DNA from blood, saliva, or a cheek swab. A laboratory reads the DNA sequence and compares it with a reference sequence, often through multigene panels, exome sequencing, or whole genome sequencing, to identify variants.
When should I consider getting a genetic test?
There is not yet a broadly established NAALADL1-specific reason for genetic testing in routine care. Testing decisions are usually based on your personal health and family history, best discussed with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but how much it explains depends 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 most useful when considered alongside other parts of care. In other situations, a genetic result can offer a clear answer. In areas like medication response, genetic results can also help place individual experiences in 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, seems weaker for another, or causes more side effects in someone else. Small inherited differences can change how the body breaks down a drug, moves it through the body, or responds to it at its target, and these differences are common.
What is Pharmacogenetics?
Pharmacogenetics examines how genetic differences shape the way a person responds to medications. It studies the relationship between genes and drugs to help explain why the same treatment may work differently in different people. For many medicines, genes influence both how strongly a drug works and how the body processes it. This information can support more informed, individualized treatment decisions.

Drugs influenced by the NAALADL1 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medicine choices, so any concerns about side effects, treatment changes, or your overall health are best discussed with your doctor.
