'''Propionic acidemia''' is an inherited disorder of [[Inborn errors of metabolism|inborn error]] of intermediary [[metabolism]] that may present in the early [[neonatal]] period with progressive [[encephalopathy]].  Death can occur at anytime due to secondary [[hyperammonemia]], infection due to immune system suppression, cardiomyopathy, or basal ganglial stroke.

==Incidence==
==[[Propionic acidemia overview|Overview]]==
[[Image:autorecessive.jpg|thumb|left|Propionic acidemia is inherited in an [[Recessive gene|autosomal recessive]] pattern.]]
Propionic acidemia is inherited in an [[autosomal recessive]] pattern and occurs in about 1 in 100,000 live births in the United States. The condition appears to be more common in Saudi Arabia with a frequency of 1 in 2,000 to 5,000 people. The condition also appears to be more common in Old Order Amish populations.


==Symptoms==
==[[Propionic acidemia  historical perspective|Historical Perspective]]==
Individuals with propionic acidemia are unable to process certain amino acids, which make up protein, and [[lipid]]s properly. The condition, which usually appears in early infancy, is characterized by poor feeding, [[vomit]]ing, weak [[muscle]] tone ([[hypotonia]]), seizures, and [[lethargy]]. The effects of propionic acidemia can be life-threatening.


==Cause==
==[[Propionic acidemia classification|Classification]]==
Mutations in the [[PCCA]] and [[PCCB]] [[gene]]s cause propionic acidemia. The PCCA and PCCB genes make protein subunits that come together to form an [[enzyme]] called [[propionyl-CoA carboxylase]] ({{EC number|6.4.1.3}}). This enzyme is responsible for one step in the breakdown of several [[amino acids]], certain lipids, and [[cholesterol]]. Mutations in the PCCA or PCCB gene disrupt the function of the enzyme, preventing these molecules from being broken down. As a result, a substance called [[propionyl-CoA]], [[propionic acid]] and other potentially [[toxic]] compounds can accumulate, causing the signs and symptoms of propionic acidemia.
