What is the official name of the FA2H gene?
The official name of this gene is “fatty acid 2-hydroxylase.”
FA2H is the gene's official symbol. The FA2H gene is also known by other names, listed below.

What is the normal function of the FA2H gene?
The FA2H gene provides instructions for making an enzyme called fatty acid 2-hydroxylase. This enzyme modifies fatty acids, which are building blocks used to make fats (lipids). Specifically, fatty acid 2-hydroxylase adds a single oxygen atom to a hydrogen atom at a particular point on a fatty acid to create a 2-hydroxylated fatty acid. Certain 2-hydroxylated fatty acids are important in forming normal myelin; myelin is the protective covering that insulates nerves and ensures the rapid transmission of nerve impulses. The part of the brain and spinal cord that contains myelin is called white matter.
How are changes in the FA2H gene related to health conditions?
Where is the FA2H gene located?
Cytogenetic Location: 16q23
Molecular Location on chromosome 16: base pairs 74,712,955 to 74,774,831
The FA2H gene is located on the long (q) arm of chromosome 16 at position 23.
More precisely, the FA2H gene is located from base pair 74,712,955 to base pair 74,774,831 on chromosome 16.
