The TMEM97 gene helps cells manage cholesterol and supports normal cell growth and recycling. If this gene does not work properly, cells may struggle to handle fats and routine cell maintenance, which can affect how tissues function. In medicine, this gene is important because it is being studied in conditions such as cancer and Alzheimer disease, where changes in cell growth, stress handling, and cholesterol balance may play a role. TMEM97 is better known in research settings than in popular culture.
What is a gene?
Genes are sections of DNA that provide cells with instructions to make molecules or regulate processes in the body. Some genes carry the directions for producing proteins, which are the working parts of cells. Other genes mainly control when certain processes take place, where they happen, and how strongly they run. Together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications. To go deeper into this topic, you can read more in the LearnHub.
Overview
TMEM97Gene function
What if the gene works
The TMEM97 gene helps cells handle cholesterol, including taking up LDL cholesterol and moving it where needed. This supports normal cell membranes and everyday cell function.
Risk
What if the gene does not work
Changes in the TMEM97 gene can range from milder to more severe variants. These may alter how cells handle cholesterol and communicate internally, changing the protein’s normal activity.
Treatment
What does that mean for your treatment
No TMEM97-specific treatment or drug selection approach is currently established for people with a pathogenic or loss-of-function variant in the TMEM97 gene. The TMEM97 gene is being studied as a possible drug target and biomarker, especially in cancer and in retinal or brain disease research, but this work has not yet changed routine care.
Gene function
What if the gene works
Your cells need a steady cholesterol supply to build membranes and keep routine processes running. The TMEM97 gene helps manage how that cholesterol is brought in and moved to the right places. Understanding TMEM97 gene function helps show how cells keep their outer covering and internal membranes in working order.
The TMEM97 gene helps cells regulate their cholesterol supply. This keeps enough cholesterol available for cell membranes, which act as the flexible outer layer and internal walls of the cell.
TMEM97 works with other cell proteins to help bring LDL cholesterol into the cell from the bloodstream. This gives cells material they use for routine membrane building and upkeep.
Once cholesterol enters the cell, TMEM97 helps route it to the places that need it. This includes movement from lysosomes (cell structures that break down and sort materials) to other cell membranes.
What is a variant?
A genetic variant is a small difference in the DNA sequence within a gene. These changes are common and help shape normal human diversity, including differences in appearance, metabolism, or how the body responds to environmental influences. Many variants do not have any noticeable effect and are simply part of natural genetic variation. Sometimes, though, a variant changes the function of a gene more significantly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
TMEM97 variants can change the protein’s shape, stability, or placement within cell membranes, which helps explain how TMEM97 variants affect protein function. Milder variants may leave some activity intact, while more severe variants can sharply reduce protein levels, disrupt membrane insertion, or produce a shortened protein that does not work well. These changes may weaken TMEM97 interactions involved in cholesterol movement and related cell signaling.
How variants are linked to conditions
Current evidence suggests the TMEM97 gene does not yet have a broadly confirmed link to a specific health condition, and research on TMEM97 gene variants linked to conditions is still evolving. Anyone with a confirmed TMEM97-related diagnosis should follow guidance from their doctor or genetic counselor.
A variant is not necessarily a diagnosis
Across the general population, genetic variants are common and are a normal feature of human biology. Most do not have a direct effect on health and simply reflect natural variation among people. For many genes, carrying a variant associated with a condition suggests a possible link rather than a definite diagnosis, especially when several genes and environmental factors also contribute. In some situations, though, one specific and 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 TMEM97 gene. Anyone concerned about personal or family risk can talk with a doctor or genetic counselor for advice based on their overall health and family history.
Inheritance of TMEM97 variants
There is not yet a broadly confirmed disease specific inheritance pattern for the TMEM97 gene, so TMEM97 gene inheritance is not described as a well established autosomal dominant, autosomal recessive, or X linked condition. The TMEM97 gene is located on chromosome 17, which is an autosome, so you inherit one copy from your mother and one copy from your father. If future research links particular TMEM97 variants to a specific condition, the inheritance pattern may become clearer.
What does my TMEM97 result mean for my family?
There is not yet a broadly confirmed inherited pattern linking TMEM97 to a specific single-gene condition in the way seen with some other genes. If you have a TMEM97 result and want to understand what it could mean for relatives, the answer depends on the exact change found and why testing was done.
Genetic information
Genetic testing
How you find out about variants
To look for variants in the TMEM97 gene, TMEM97 genetic testing uses a blood or saliva sample. A laboratory reads the DNA code in this gene, often as part of a larger gene panel or broader DNA test, 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, TMEM97-specific reason for genetic testing in routine care. Decisions about testing are usually based on your symptoms, other health findings, and family history, with guidance from 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 kind of variant involved. Over time, many factors, including lifestyle, environment, age, and medical history, also influence how the body works. For some conditions, especially those shaped by many genes, genetic information offers context rather than certainty and is best understood together with other parts of care. In other situations, a genetic result may give a clear answer. In areas like medication response, these 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. Small differences in DNA can change how the body absorbs, breaks down, transports, or responds to a drug, so the same treatment may work better for one person than for another. These differences are common and can influence both how well a medicine helps and how likely someone is to notice side effects.
What is Pharmacogenetics?
Pharmacogenetics studies how differences in genes can 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. For many medicines, genes affect both how strongly a drug works and how the body processes it. This information can support more informed and individualized treatment decisions.

Drugs influenced by the TMEM97 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in predicting how medicines will work, so questions about side effects, new symptoms, or medication changes are best discussed with your doctor.
History
TMEM97 entered the scientific literature under other names before its role became clearer over time. Initially understood only through visible traits, later recognized as tied to a specific gene, it was studied in cancer research, where altered activity was noted in some tumors. Interest in this gene grew further as researchers investigated the long-mysterious sigma-2 receptor, a cell protein linked to cell growth and stress responses. A major step came in 2017, when studies identified TMEM97 as the sigma-2 receptor. From these first observations, research expanded steadily. That finding gave earlier laboratory work a clearer framework and made TMEM97 more relevant in studies of cancer, brain biology, and drug development.
