MMADHC

Methylmalonic aciduria and homocystinuria type D protein, mitochondrial also known as MMADHC is a protein that in humans is encoded by the MMADHC gene.^[1]

Function

This gene encodes a mitochondrial protein that is involved in an early step of vitamin B₁₂ metabolism. Vitamin B₁₂ (cobalamin) is essential for normal development and survival in humans.^[2]

Clinical significance

Mutations in this gene cause methylmalonic aciduria and homocystinuria type cblD (MMADHC), a disorder of cobalamin metabolism that is characterized by decreased levels of the coenzymes adenosylcobalamin and methylcobalamin.^[1]
