The SLC37A3 gene helps cells move certain substances out of lysosomes, the small compartments that break down and recycle material. It is especially important for how the body’s cells respond to bisphosphonates, a group of medicines used for osteoporosis and some other bone conditions. If the gene does not work, these medicines may have less effect because they do not reach their target inside the cell as well. Understanding this gene can help clarify why treatment response can differ from one person to another.
What is a gene?
Genes are stretches of DNA that provide instructions your cells use to make molecules or regulate processes in the body. Some genes carry the information needed to produce proteins, the parts of cells that do much of the work. Other genes mainly help control when certain processes happen, where they happen, and how active they are. Together, genes affect how the body develops and works, and they can also shape how you respond to food, stress, or medications.

Overview
SLC37A3Gene function
What if the gene works
Inside cells, the SLC37A3 gene helps move certain molecules across lysosome membranes. This supports normal recycling and handling of materials within the cell.
Risk
What if the gene does not work
More severe variants in the SLC37A3 gene can cause osteopetrosis, with overly dense bones that may affect growth and vision or hearing. Milder variants may lead to later onset or fewer features.
Treatment
What does that mean for your treatment
Pathogenic or loss-of-function variants in the SLC37A3 gene do not currently have an established gene-specific treatment or management approach. This gene is being studied as a drug response factor because reduced SLC37A3 activity may lessen the effect of nitrogen containing bisphosphonates, including alendronate and zoledronic acid.
Gene function
What if the gene works
Inside your cells, the SLC37A3 gene supports transport across lysosomes, the small compartments that process materials after they are taken up. Its protein sits in the lysosome membrane and helps move selected substances into the main part of the cell. Understanding how the SLC37A3 gene works helps explain how some bone medicines reach their target inside cells.
Its protein sits in the membrane of the lysosome, a small compartment that processes materials inside cells. From there, it provides a route for certain substances to cross into the cell's main fluid.
Inside your cells, SLC37A3 works closely with a partner protein called ATRAID. Together, they form a working pair that supports transport at the lysosome membrane.
This transport role is especially important for nitrogen containing bisphosphonates, a group of bone medicines. It helps these medicines leave the lysosome so they can act in the right part 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 help shape normal human diversity, including differences in appearance, metabolism, and how the body responds to environmental influences. Many variants do not have any noticeable effect and simply reflect natural genetic variation. Sometimes, though, 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
SLC37A3 gene variants can change how much protein a cell makes, how well it folds, and whether it reaches the lysosome, the cell's recycling compartment, and binds its partner protein ATRAID. This helps explain how SLC37A3 gene variants affect lysosomal transport: some single letter DNA changes leave partial activity, while more disruptive variants can lead to very little or no working protein. The result can range from a mild reduction in transport to near complete loss.
How variants are linked to conditions
Current evidence on SLC37A3 gene variants linked to disease has not established a broadly confirmed connection to a specific health condition, though this may change as research develops. If you carry a confirmed variant in the SLC37A3 gene, your doctor or genetic counselor can explain what it may mean for you and your family.
A variant is not necessarily a diagnosis
Genetic variants are a normal feature of human biology and are common in the general population. Most do not have a direct effect on health and simply represent 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 are involved. In some cases, though, 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 specifically related to the SLC37A3 gene. If a change in SLC37A3 has been found in your family or on testing, a doctor or genetic counselor can help explain what it may mean for your personal risk.
Inheritance of SLC37A3 variants
There is not yet a broadly confirmed inheritance pattern tied to a specific condition for the SLC37A3 gene, so how SLC37A3 gene variants are inherited in a disease setting is still being clarified. The SLC37A3 gene is located on chromosome 7, which is an autosome. That means each person usually has two copies of this gene, with one inherited from each parent.
What does my SLC37A3 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific condition for SLC37A3, although this can become clearer as research grows. If you have a specific SLC37A3 result and want to understand what it could mean for relatives, a doctor or genetic counselor can help explain it in the context of your family history and the exact variant found.
Genetic information
Genetic testing
How you find out about variants
To look for changes linked to this condition, genetic testing for SLC37A3 variants usually uses a blood or saliva sample. A lab reads the DNA sequence and checks for spelling changes or missing pieces in the SLC37A3 gene. Results may show a pathogenic variant, a benign variant, or an uncertain finding.
When should I consider getting a genetic test?
There isn't yet a broadly established SLC37A3-specific reason for genetic testing in routine care. Testing decisions are usually made with a doctor or genetic counselor based on your symptoms, family history, and whether a broader gene test fits the health question.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but how much it explains varies based on the condition and the specific variant involved. Over time, how the body works is also influenced by many factors, including lifestyle, environment, age, and medical history. In some conditions, especially those shaped by many genes, genetic information offers context rather than certainty and is best considered together with other parts of care. In other situations, a genetic result can give a clear answer. In areas such as response to medication, genetic results can also help make individual experiences easier to understand.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how your body responds to medicines. Small differences in genes can change how a drug is absorbed, broken down, moved through the body, or how strongly it acts at its target. This helps explain why the same medication may work well for one person, have less effect in another, or cause more side effects in someone who is more sensitive to it.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in a person’s genes affect the way they respond to medicines. It looks at gene and drug patterns to help explain why the same treatment can work differently in different people. For many medications, genes influence both how strongly a drug works and how the body processes it. This information can support more informed and more individualized treatment decisions. More detail on this topic is available in the LearnHub.
Drugs influenced by the SLC37A3 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in how doctors choose medicines. General questions about side effects, bone treatment, or other medication concerns are best discussed with your doctor. SLC37A3 has been studied in research on some bone-strengthening medicines called bisphosphonates, but this has not become part of routine medical care.
