Carboxyl ester lipase

The gene CEL encodes a glycoprotein secreted from the pancreas and the lactating mammary gland. Its function is to cleave cholesterol esters ti facilitate its absorption in the digestive tract.

Gene Structure

In exon 11 there is a variable number of repeats (VNTR) found in normal controls (7-23). A study found a correlation between only three such repeats and the incidence of diabetes. These findings were not generally approved, so now it is considered suffient criterion for the diagnosis of type 8 MODY.[Error: Macro 'ref' doesn't exist]
