Propionic acidemia (pa), one of the most frequent life-threatening organic acidemias, is caused by mutations in either the pcca or pccb genes encoding both subunits of the mitochondrial propionyl-coa carboxylase (pcc) enzyme. Cardiac alterations (hypertrophy, dilated cardiomyopathy, long qt) are one of the major causes of mortality in patients surviving the neonatal period.
Propionic acidemia has an autosomal recessive pattern of inheritance. In healthy individuals, enzyme propionyl-coa carboxylase converts propionyl-coa to methylmalonyl-coa. This is one of many steps in the process of converting certain amino acids and fats into energy.
