Gene Gene information from NCBI Gene database.
Entrez ID 11277
Gene name Three prime repair exonuclease 1
Gene symbol TREX1
Synonyms (NCBI Gene)
AGS1CRVDRN3HERNSRVCLS
Chromosome 3
Chromosome location 3p21.31
Summary This gene encodes a nuclear protein with 3` exonuclease activity. The encoded protein may play a role in DNA repair and serve as a proofreading function for DNA polymerase. Mutations in this gene result in Aicardi-Goutieres syndrome, chilblain lupus, Cree
