Funkcija[uredi | uredi izvor]

Protein koji je kodiran ovim genom uključen je u translokaciju kobalamina u mitohondrije, gdje se koristi u završnim koracima sinteze adenozilkobalamina. Adenozilkobalamin je koenzim potreban za aktivnost metilmalonil-CoA mutaza.^[7]

Klinički značaj[uredi | uredi izvor]

Mutacije u genu MMAA povezane su sa metilmalonskom acidemijom.^[5]^[8]
