organic acid disorder in which the body is unable to process certain parts of proteins and lipids (fats) properly, and abnormal levels of propionic acid build up in the blood and tissues. The levels are toxic and cause serious health problems. In most cases, the features of propionic acidemia become apparent within a few days after birth and include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). These symptoms sometimes progress to more serious medical problems, including heart abnormalities, seizures, coma, and possibly death. It is caused by mutations in the PCCA and PCCB genes, which provide instructions for making a certain enzyme needed to break down proteins. It is inherited in an autosomal recessive pattern. Treatment is life-long and involves appropriate dietary management (to limit intake of certain amino acids) and addressing symptoms during a metabolic crisis.Propionic acidemia is an
