What is the official name of the LIPA gene?
The official name of this gene is “lipase A, lysosomal acid, cholesterol esterase.”
LIPA is the gene's official symbol. The LIPA gene is also known by other names, listed below.
Read more about gene names and symbols on the About page.
What is the normal function of the LIPA gene?
The LIPA gene provides instructions for making an enzyme called lysosomal acid lipase. This enzyme is found in the lysosomes (compartments that digest and recycle materials in the cell), where it breaks down fats (lipids) such as cholesteryl esters and triglycerides.
In the body, cholesterol works with high-density lipoproteins (HDL), often referred to as "good cholesterol." High-density lipoproteins carry cholesterol from the body's tissues to the liver for removal. When the cholesterol is attached to a fatty acid it is a cholesteryl ester. Normally, the cholesteryl esters are broken down by lysosomal acid lipase into cholesterol and a fatty acid and then excreted or used by the body as nutrients.
How are changes in the LIPA gene related to health conditions?
Where is the LIPA gene located?
Cytogenetic Location: 10q23.2-q23.3
Molecular Location on chromosome 10: base pairs 89,213,569 to 89,252,039
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The LIPA gene is located on the long (q) arm of chromosome 10 between positions 23.2 and 23.3.
More precisely, the LIPA gene is located from base pair 89,213,569 to base pair 89,252,039 on chromosome 10.
