DNA2 (DNA Replication Helicase/Nuclease 2) is a Protein Coding gene. Diseases associated with DNA2 include Progressive External Ophthalmoplegia With Mitochondrial Dna Deletions, Autosomal Dominant 6 and Seckel Syndrome 8. Among its related pathways are DNA Double-Strand Break Repair and Telomere C-strand (Lagging Strand) Synthesis. DNA2 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 DNA2 are associated with autosomal dominant progressive external ophthalmoplegia-6 (PEOA6) and Seckel syndrome 8. Alternatively spliced transcript variants have been found for DNA2.
