Acidemia metilmalonică
Autozomal recesivă
Cauzată de variante ale genelor MMUT, MMAA, MMAB, MCEE și ale altor gene implicate în procesarea cobalaminei, care pot provoca vărsături, alimentație slabă, crize metabolice, probleme de dezvoltare și boală renală.
Ce schimbă un diagnostic
Cunoașterea acestei afecțiuni permite gestionarea dietetică specializată, administrarea de carnitină, vitamina B12 pentru formele sensibile la aceasta și un plan de urgență, ceea ce reduce riscul de crize.
