Notes
aka c.545G>A (p.Arg182His or R182H), and also c.545G>T (p.Arg182Leu or R182L); the former is considered pathogenic in ClinVar for a hereditary cancer-predisposing syndrome (polyposis), while the latter is a variant of uncertain significance.
C;T
Unaffected in absence of a second MUTYH gene mutation
