The severity of the mutation to the gene will determine how severe the symptoms of GA-2 are and also determine the prognosis (Man-Chun, 1992). The most severe GA-2 is apparent at or shortly after birth. [sites.google.com]

Etiology MADD is caused by mutations in the ETFA (15q23-q25), ETFB (19q13.3-q13.4) and ETFDH (4q32-q35) genes which encode the alpha and beta subunits of electron transfer flavoprotein (ETF) and ETF-coenzyme Q oxidoreductase. [orpha.net]

Here we present an infant with MADD in whom the previously reported dose of 3-HB did not prevent the acute, severe, metabolic decompensation or progressive cardiomyopathy in the subsequent months. [ncbi.nlm.nih.gov]

Therefore, prevention of reaching this catabolic threshold seems to be the best therapeutic option in most, but not all patients. [clinicaladvisor.com]
