Genes affected

REXO2 (HGNC:17851): (RNA exonuclease 2) This gene encodes a 3'-to-5' exonuclease specific for small (primarily 5 nucleotides or less in length) single-stranded RNA and DNA oligomers. This protein may have a role in DNA repair, replication, and recombination, and in RNA processing and degradation. It may also be involved in resistance of human cells to UV-C-induced cell death through its role in the DNA repair process. [provided by RefSeq, Nov 2011]

Oct 27, 2022

The c.413C>T (p.P138L) alteration is located in exon 4 (coding exon 4) of the REXO2 gene. This alteration results from a C to T substitution at nucleotide position 413, causing the proline (P) at amino acid position 138 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
