ACIDEMIA PROPIONICA PDF

Propionic acidemia is an inherited disorder in which the body is unable to process certain parts of proteins and lipids (fats) properly. It is classified as an organic. The spectrum of propionic acidemia (PA) ranges from neonatal-onset to late- onset disease. A number sign (#) is used with this entry because propionic acidemia is caused by mutation in the genes encoding propionyl-CoA carboxylase, PCCA ().
