Genes affected
TREX2 (HGNC:12270): (three prime repair exonuclease 2) This gene encodes a nuclear protein with 3' to 5' exonuclease activity. The encoded protein participates in double-stranded DNA break repair, and may interact with DNA polymerase delta. [provided by RefSeq, Nov 2012]

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.541C>T (p.R181W) alteration is located in exon 2 (coding exon 1) of the TREX2 gene. This alteration results from a C to T substitution at nucleotide position 541, causing the arginine (R) at amino acid position 181 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
