We report a new germline mutation in exon 13 of the hMSH2 gene (c.2081T>C; F694S) in a patient diagnosed with colorectal carcinoma. The patient's family fulfilled the clinical criteria of the Bethesda guidelines for Lynch syndrome. The segregation analysis determined the presence of the mutation in the proband's mother (breast cancer younger than 40 years old) and in two healthy daughters. The mutation was not present in 116 normal controls screened. The medical implications for the carrier relatives are discussed.
