Methylmalonsyreacidæmi
Autosomal recessiv
Forårsaget af varianter i MMUT, MMAA, MMAB, MCEE og beslægtede gener for cobalaminbearbejdning, som kan give opkastning, dårlig fødeindtagelse, metaboliske kriser, udviklingsproblemer og nyresygdom.
Hvad en diagnose ændrer
Viden gør det muligt at få specialiseret kostbehandling, carnitin, vitamin B12 ved de former, der responderer på det, og en nødplan, hvilket reducerer risikoen for kriser.
