Gene Gene information from NCBI Gene database.
Entrez ID 54840
Gene name Aprataxin
Gene symbol APTX
Synonyms (NCBI Gene)
AOAAOA1AXA1EAOHEOAHAFHA-HIT
Chromosome 9
Chromosome location 9p21.1
Summary This gene encodes a member of the histidine triad (HIT) superfamily. The encoded protein may play a role in single-stranded DNA repair through its nucleotide-binding activity and its diadenosine polyphosphate hydrolase activity. Mutations in this gene hav
