Prevalence and spectrum of MLH1, MSH2, and MSH6 pathogenic germline variants in Pakistani colorectal cancer patients.

ABSTRACT:

Background

Pathogenic germline variants in MLH1, MSH2 and MSH6 genes account for the majority of Lynch syndrome (LS). In this first report from Pakistan, we investigated the prevalence of pathogenic MLH1/MSH2/MSH6 variants in colorectal cancer (CRC) patients.

Methods

Consecutive cases (n = 212) were recruited at the Shaukat Khanum Memorial Cancer Hospital and Research Centre (SKMCH&RC), between November 2007 to March 2011. Patients with a family history of > 3 or 2 HNPCC-associated cancers were classified as HNPCC (n = 9) or suspected-HNPCC (n = 20), respectively (group 1; n = 29). Cases with no family history were designated as non-HNPCC (group 2; n = 183). MLH1/MSH2/MSH6 genes were comprehensively screen
