What is the official name of the EBP gene?
The official name of this gene is “emopamil binding protein (sterol isomerase).”
EBP is the gene's official symbol. The EBP gene is also known by other names, listed below.

What is the normal function of the EBP gene?
The EBP gene provides instructions for making an enzyme called 3β-hydroxysteroid-Δ8,Δ7-isomerase. This enzyme is responsible for one of the final steps in the production of cholesterol. Specifically, it converts a molecule called 8(9)-cholestenol to lathosterol. Other enzymes then modify lathosterol to produce cholesterol.
Cholesterol is a waxy, fat-like substance that is produced in the body and obtained from foods that come from animals (particularly egg yolks, meat, poultry, fish, and dairy products). Although too much cholesterol is a risk factor for heart disease, this molecule is necessary for normal embryonic development and has important functions both before and after birth. It is a structural component of cell membranes and plays a role in the production of certain hormones and acids used in digestion (bile acids).

Where is the EBP gene located?
Cytogenetic Location: Xp11.23-p11.22
Molecular Location on the X chromosome: base pairs 48,521,776 to 48,528,716
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The EBP gene is located on the short (p) arm of the X chromosome between positions 11.23 and 11.22.
More precisely, the EBP gene is located from base pair 48,521,776 to base pair 48,528,716 on the X chromosome.
