DNA2 - DNA replication helicase/nuclease 2 Gene

Also Known as DNA2L; hDNA2

Species: Homo sapiens

Gene Type: protein coding
Gene ID: 1763

About DNA2

Cytogenetic location: 10q21.3 Genomic coordinates (GRCh38): 10:68,414,064-68,472,521 (from NCBI)

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]
