What is the official name of the INS gene?
The official name of this gene is “insulin.”
INS is the gene's official symbol. The INS 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 INS gene?
The INS gene provides instructions for producing the hormone insulin, which is necessary for the control of glucose levels in the blood. Glucose is a simple sugar and the primary energy source for most cells in the body.
Insulin is produced in a precursor form called proinsulin, which consists of a single chain of protein building blocks (amino acids). The proinsulin chain is cut (cleaved) to form individual pieces called the A and B chains, which are joined together by connections called disulfide bonds to form insulin.
How are changes in the INS gene related to health conditions?
Genetics Home Reference provides information about type 1 diabetes, which is also associated with changes in the INS gene.
Where is the INS gene located?
Cytogenetic Location: 11p15.5
Molecular Location on chromosome 11: base pairs 2,159,779 to 2,161,209
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The INS gene is located on the short (p) arm of chromosome 11 at position 15.5.
More precisely, the INS gene is located from base pair 2,159,779 to base pair 2,161,209 on chromosome 11.
