Genes affected

SAMM50 (HGNC:24276): (SAMM50 sorting and assembly machinery component) This gene encodes a component of the Sorting and Assembly Machinery (SAM) of the mitochondrial outer membrane. The Sam complex functions in the assembly of beta-barrel proteins into the outer mitochondrial membrane.[provided by RefSeq, Jun 2011]
