The ABCA13 gene helps cells move certain fats across their outer membrane, which supports normal cell function and signaling, especially in the brain. If this gene does not work as expected, cells may handle these fats less effectively, which can affect how they communicate. Some differences in this gene can change how brain cells work and have been linked to conditions such as schizophrenia, bipolar disorder, and some cancers, but a variant alone does not make a diagnosis. ABCA13 is better known in medical research than in popular culture.
What is a gene?
Genes are stretches of DNA that carry instructions 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. Others mostly guide 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, and medications.

Overview
ABCA13Gene function
What if the gene works
The ABCA13 gene helps make a transporter protein that moves fats across cell membranes. This activity may support normal cell membrane function, especially in the brain and other tissues.
Risk
What if the gene does not work
Milder to more severe variants in the ABCA13 gene can partly reduce or more fully disrupt this cell membrane transporter, which helps move certain fats within cells. This may alter membrane lipid handling and normal vesicle movement.
Treatment
What does that mean for your treatment
No treatment or management approach specific to the ABCA13 gene is currently established for a pathogenic or loss-of-function variant. The ABCA13 gene is being studied as a possible biomarker in some psychiatric and cancer research, but this has not changed routine drug choices.
Gene function
What if the gene works
Inside your cells, the ABCA13 gene helps power the movement of certain molecules across the cell membrane. It belongs to a transporter family that uses ATP, the cell's main energy source, to shift material from one side of a membrane to the other. This gives a practical picture of how the ABCA13 gene helps move fats across cell membranes during routine cell activity.
The ABCA13 gene helps cells move selected molecules across membranes. It uses ATP, the cell's energy source, to power that transport.
This gene is linked to the movement and handling of fats that form cell membranes. That work helps cells keep their outer surface organized and stable.
What is a variant?
A genetic variant is a small difference in the DNA sequence of a gene. These changes are common and help create normal human diversity, such as differences in appearance, metabolism, or the way the body responds to environmental influences. Many variants do not have any noticeable effect and simply represent natural genetic variation. In some situations, however, a variant can change 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 ABCA13 gene can change the protein's shape, stability, or movement within the cell, which helps explain how ABCA13 gene variants affect protein function. Some single-letter DNA changes may partly weaken energy-powered transport, while more disruptive variants can shorten the protein or prevent it from reaching the cell surface. This creates a spectrum from milder functional changes to near-complete loss of activity.
How variants are linked to conditions
Variants in the ABCA13 gene do not yet have a broadly confirmed link to a specific health condition, although research on how ABCA13 gene variants are linked to conditions is still developing. If you have a confirmed finding in the ABCA13 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
Genetic variants are a routine part of human biology and are widely found in the general population. Most do not have a direct effect on health and instead reflect normal human diversity. For many genes, carrying a variant associated with a condition indicates a possible link rather than a definite diagnosis, especially when several genes and environmental factors contribute. In some situations, however, a single well-characterized variant in a particular 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 ABCA13 gene. Because research is still developing, anyone concerned about personal or family risk should talk with a doctor or genetic counselor.
Inheritance of ABCA13 variants
There is not yet a broadly confirmed, disease specific inheritance pattern for ABCA13 gene variants, and current evidence does not support a single well established Mendelian pattern for ABCA13 gene inheritance. The ABCA13 gene is located on chromosome 7, which is an autosome, so you inherit one copy of the ABCA13 gene from your mother and one copy from your father. In general, that means any ABCA13 related genetic finding can be passed through either side of the family.
What does my ABCA13 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for the ABCA13 gene, and research is still developing. If you have a specific ABCA13 result, its meaning for parents, children, brothers, sisters, or other relatives depends on the exact change found and the reason testing was done.
Genetic information
Genetic testing
How you find out about variants
To look for changes in the ABCA13 gene, a lab usually studies DNA from a blood sample, saliva sample, or cheek swab. How ABCA13 genetic testing works is straightforward: the lab reads the gene’s DNA code and compares it with the usual sequence to see whether a variant is present.
When should I consider getting a genetic test?
There is not yet a broadly established reason to order genetic testing just for the ABCA13 gene. 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
Genetic test results can provide useful insight, though how much they reveal varies with the condition and the kind of variant involved. Over time, the way the body functions is also shaped by many factors, including lifestyle, environment, age, and medical history. For some conditions, particularly those affected by many genes, genetic information offers context rather than certainty and makes the most sense when considered with other parts of care. In other situations, a genetic result can give a clear answer. In areas such as medication response, these results can also help put individual experiences in context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Some people break down or move a drug through the body differently, so the same treatment may work better for one person, have less effect in another, or cause more side effects in someone else. These differences are common and are one reason medication response can vary from person to person.
What is Pharmacogenetics?
Pharmacogenetics is the area of study that looks at how differences in genes affect a person’s response to medicines. It examines gene and drug patterns to help explain why the same treatment may work differently in different people. For many medicines, genes influence how strong a drug’s effects are or how the body handles it. This information can support more informed, more personalized treatment decisions. You can learn more about this topic in the LearnHub.
Drugs influenced by the ABCA13 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medication response, so general questions about side effects, new symptoms, or whether a treatment is working are best discussed with your doctor. Seek medical advice promptly if symptoms suddenly worsen or a medicine causes concerning reactions.
History
The ABCA13 gene entered the scientific literature in the early 2000s as researchers mapped and compared members of the ATP binding cassette gene family, a large group of genes involved in moving substances across cell membranes. Early interest centered on its unusually large size, which made it stand out among related genes. From these first observations, research expanded steadily, and later studies explored whether variants in the ABCA13 gene might be linked to some psychiatric conditions and cancers. Its history is mainly a research story rather than a public one, with growing attention as genetic sequencing made it easier to study large genes in more detail.
