Summaries for TREX1 Gene

Entrez Gene Summary for TREX1 Gene

  • 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 encephalitis, and other diseases of the immune system. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2012]

GeneCards Summary for TREX1 Gene

TREX1 (Three Prime Repair Exonuclease 1) is a Protein Coding gene. Diseases associated with TREX1 include Chilblain Lupus and Aicardi-Goutieres Syndrome 1, Dominant And Recessive. Among its related pathways are Innate Immune System and Cytosolic sensors of pathogen-associated DNA. GO annotations related to this gene include nucleic acid binding and double-stranded DNA binding. An important paralog of this gene is TREX2.

UniProtKB/Swiss-Prot for TREX1 Gene

  • Major cellular 3-to-5 DNA exonuclease which digests single-stranded DNA (ssDNA) and double-stranded DNA (dsDNA) with mismatched 3 termini. Prevents cell-intrinsic initiation of autoimmunity. Acts by metabolizing DNA fragments from endogenous retroelements, including L1, LTR and SINE elements. Unless degraded, these DNA fragments accumulate in the cytosol and activate the IFN-stimulatory DNA (ISD) response and innate immune signaling. Prevents chronic ATM-dependent checkpoint activation, by processing ssDNA polynucleotide species arising from the processing of aberrant DNA replication intermediates. Inefficiently degrades oxidized DNA, such as that generated upon antimicrobial reactive oxygen production or upon absorption of UV light. During GZMA-mediated cell death, contributes to DNA damage in concert with NME1. NME1 nicks one strand of DNA and TREX1 removes bases from the free 3 end to enhance DNA damage and prevent DNA end reannealing and rapid repair.

  • Aicardi-Goutieres syndrome 1 (AGS1) [MIM:225750]: A form of Aicardi-Goutieres syndrome, a genetically heterogeneous disease characterized by cerebral atrophy, leukoencephalopathy, intracranial calcifications, chronic cerebrospinal fluid (CSF) lymphocytosis, increased CSF alpha-interferon, and negative serologic investigations for common prenatal infection. Clinical features as thrombocytopenia, hepatosplenomegaly and elevated hepatic transaminases along with intermittent fever may erroneously suggest an infective process. Severe neurological dysfunctions manifest in infancy as progressive microcephaly, spasticity, dystonic posturing and profound psychomotor retardation. Death often occurs in early childhood. {ECO:0000269 PubMed:16845398, ECO:0000269 PubMed:17293595, ECO:0000269 PubMed:17357087, ECO:0000269 PubMed:17846997, ECO:0000269 PubMed:18045533, ECO:0000269 PubMed:20131292, ECO:0000269 PubMed:20799324, ECO:0000269 PubMed:23979357}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Chilblain lupus 1 (CHBL1) [MIM:610448]: A rare cutaneous form of lupus erythematosus. Affected individuals present with painful bluish-red papular or nodular lesions of the skin in acral locations precipitated by cold and wet exposure at temperatures less than 10 degrees centigrade. {ECO:0000269 PubMed:17357087, ECO:0000269 PubMed:17440703}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Systemic lupus erythematosus (SLE) [MIM:152700]: A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow. {ECO:0000269 PubMed:17660818, ECO:0000269 PubMed:20131292, ECO:0000269 PubMed:23979357}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry. Enhanced immune sensing of oxidized DNA may be involved in the phototoxicity experienced by SLE patients. Exposure to UV-light produces DNA oxidative damage. Oxidized DNA being a poor TREX1 substrate, it accumulates in skin, leading to enhanced auto-immune reactivity and eventually skin lesions (PubMed:23993650). {ECO:0000269 PubMed:23993650}.
  • Vasculopathy, retinal, with cerebral leukodystrophy (RVCL) [MIM:192315]: A microvascular endotheliopathy resulting in central nervous system degeneration and retinopathy, with progressive loss of vision, stroke, motor impairment, and cognitive decline. The ocular manifestations are characterized by telangiectasias, microaneurysms and retinal capillary obliteration starting in the macula. Diseased cerebral white matter has prominent small infarcts that often coalesce to pseudotumors. {ECO:0000269 PubMed:17660820}. Note=The disease is caused by mutations affecting the gene represented in this entry.
