MTDPS7

Chr 10AR

twinkle mtDNA helicase

Also known as: ATXN8, C10orf2, IOSCA, MTDPS7, PEO, PEO1, PEOA3, PRLTS5

This gene encodes a hexameric DNA helicase that unwinds double-stranded DNA in the 5' to 3' direction and plays a key role in mitochondrial DNA replication along with mitochondrial single-stranded DNA binding protein and mtDNA polymerase gamma. Mutations cause mitochondrial DNA depletion syndrome 7 (hepatocerebral type), which can present with infantile onset spinocerebellar ataxia and progressive external ophthalmoplegia. The condition follows autosomal recessive inheritance.
