Genes affected

XRCC6 (HGNC:4055): (X-ray repair cross complementing 6) The p70/p80 autoantigen is a nuclear complex consisting of two subunits with molecular masses of approximately 70 and 80 kDa. The complex functions as a single-stranded DNA-dependent ATP-dependent helicase. The complex may be involved in the repair of nonhomologous DNA ends such as that required for double-strand break repair, transposition, and V(D)J recombination. High levels of autoantibodies to p70 and p80 have been found in some patients with systemic lupus erythematosus. [provided by RefSeq, Jul 2008]

The c.1669G>C (p.V557L) alteration is located in exon 13 (coding exon 12) of the XRCC6 gene. This alteration results from a G to C substitution at nucleotide position 1669, causing the valine (V) at amino acid position 557 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
