DNA2 - DNA replication helicase/nuclease 2 Gene
Also Known as DNA2L; hDNA2
Species: Homo sapiens
About DNA2
This gene has 8 transcripts (splice variants), 172 orthologues, 10 paralogues and is associated with 4 phenotypes. Broad expression in lymph node (RPKM 2.7), testis (RPKM 1.9) and 24 other tissues.
Summary
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]
