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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 04, 2024The c.586G>T (p.D196Y) alteration is located in exon 6 (coding exon 5) of the EXO1 gene. This alteration results from a G to T substitution at nucleotide position 586, causing the aspartic acid (D) at amino acid position 196 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
