Genes affected
PMPCA (HGNC:18667): (peptidase, mitochondrial processing subunit alpha) The protein encoded by this gene is found in the mitochondrion, where it represents the alpha subunit of a proteolytic heterodimer. This heterodimer is responsible for cleaving the transit peptide from nuclear-encoded mitochondrial proteins. Defects in this gene are a cause of spinocerebellar ataxia, autosomal recessive 2. [provided by RefSeq, Mar 2016]
ENTR1 (HGNC:10667): (endosome associated trafficking regulator 1) Involved in several processes, including endocytic recycling; positive regulation of cilium assembly; and positive regulation of protein localization to cilium. Located in endosome; microtubule organizing center; and midbody. Colocalizes with retromer complex. [provided by Alliance of Genome Resources, Apr 2022]
