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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 02, 2023The c.129G>A (p.M43I) alteration is located in exon 1 (coding exon 1) of the REXO2 gene. This alteration results from a G to A substitution at nucleotide position 129, causing the methionine (M) at amino acid position 43 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
