MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a deoxyribonucleoside kinase that specifically phosphorylates thymidine, deoxycytidine, and deoxyuridine. The encoded enzyme localizes to the mitochondria and is required for mitochondrial DNA synthesis. Mutations in this gene are associated with a myopathic form of mitochondrial DNA depletion syndrome. Alternate splicing results in multiple transcript variants encoding distinct isoforms, some of which lack transit peptide, so are not localized to mitochondria. [provided by RefSeq, Dec 2012]
PHENOTYPE: Knock-out mice die at 2-4 wks of age showing stunted growth, hypothermia, progressive mtDNA loss, aberrant myocardial fibers and altered adipose tissue structure. Knock-in mutant mice show encephalomyelopathy, impaired gait, mtDNA loss, altered mt dNTP pools and respiratory chain enzyme activities. [provided by MGI curators]
