What is the official name of the FH gene?
The official name of this gene is “fumarate hydratase.”
FH is the gene's official symbol. The FH 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 FH gene?
The FH gene provides instructions for making an enzyme called fumarase (also known as fumarate hydratase). Fumarase participates in an important series of reactions known as the citric acid cycle or Krebs cycle, which allows cells to use oxygen and generate energy. Specifically, fumarase helps convert a molecule called fumarate to a molecule called malate.
How are changes in the FH gene related to health conditions?
Where is the FH gene located?
Cytogenetic Location: 1q42.1
