background:
C2ORF25 is a mitochondrial protein and its function is not fully identified. But, Vitamin B12 (cobalamin) is an essential cofactor in several metabolic pathways. Intracellular conversion of cobalamin to adenosylcobalamin in mitochondria and to methylcobalamin in cytoplasm is necessary for homeostasis of methylmalonic acid and homocysteine. C2ORF25 encodes a protein involved in an early step of cobalamin metabolism.
Function:
nvolved in cobalamin metabolism.
Subcellular Location:
Mitochondrial.
Tissue Specificity:
Widely expressed at high levels.
DISEASE:
Defects in MMADHC are the cause of methylmalonic aciduria and homocystinuria type cblD (MMAHCD) [MIM:277410]. A disorder of cobalamin metabolism characterized by decreased levels of the coenzymes adenosylcobalamin (AdoCbl) and methylcobalamin (MeCbl). Clinical features include developmental delay, hyotonia, mental retardation, seizures, megaloblastic anemia. Some patients manifest combined methylmalonic aciduria and homocystinuria (referred to as cblD original), some have only isolated homocystinuria (cblD variant 1), and others have only methylmalonic aciduria (cblD variant 2).
