What is glutamate formiminotransferase deficiency

Glutamate formiminotransferase deficiency is an inherited (genetic) condition that prevents the breakdown of histidine. Histidine is an amino acid, one of the building blocks that makes up proteins.

Formiminotransferase cyclodeaminase (FTCD) is an enzyme in your body that helps break down histidine. This enzyme also helps make an important vitamin called folate.

Without enough working FTCD enzyme, your baby will have trouble breaking down histidine and making folate. Most babies with glutamate formiminotransferase deficiency are well or have very few signs and symptoms.
