What is the official name of the APRT gene?
The official name of this gene is “adenine phosphoribosyltransferase.”
APRT is the gene's official symbol. The APRT gene is also known by other names, listed below.

What is the normal function of the APRT gene?
The APRT gene provides instructions for making an enzyme called adenine phosphoribosyltransferase (APRT). This enzyme is produced in all cells and is part of the purine salvage pathway, which recycles a group of DNA building blocks (nucleotides) called purines to make other molecules. The APRT enzyme helps to recycle the purine adenine to make a molecule called adenosine monophosphate (AMP). This conversion occurs when AMP is needed as a source of energy for cells.
How are changes in the APRT gene related to health conditions?
Where is the APRT gene located?
Cytogenetic Location: 16q24
Molecular Location on chromosome 16: base pairs 88,809,469 to 88,811,934
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The APRT gene is located on the long (q) arm of chromosome 16 at position 24.
More precisely, the APRT gene is located from base pair 88,809,469 to base pair 88,811,934 on chromosome 16.
