Genes affected

EXO1 (HGNC:3511): (exonuclease 1) This gene encodes a protein with 5' to 3' exonuclease activity as well as an RNase H activity. It is similar to the Saccharomyces cerevisiae protein Exo1 which interacts with Msh2 and which is involved in mismatch repair and recombination. Alternative splicing of this gene results in three transcript variants encoding two different isoforms. [provided by RefSeq, Jul 2008]

The c.436G>A (p.V146M) alteration is located in exon 5 (coding exon 4) of the EXO1 gene. This alteration results from a G to A substitution at nucleotide position 436, causing the valine (V) at amino acid position 146 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
