MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the DNA2/NAM7 helicase family. The encoded protein is a conserved helicase/nuclease involved in the maintenance of mitochondrial and nuclear DNA stability. Mutations in this gene are associated with autosomal dominant progressive external ophthalmoplegia-6 (PEOA6) and Seckel syndrome 8. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2014]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit embryonic lethality before E7.5. Mice heterozygous for the allele exhibit shortened telomeres, chromosome segregation errors and increased tumor incidence associated with aneuploidy. [provided by MGI curators]
