“…Germline variants in PC susceptibility genes in individuals with IPMN include STK11 , MSH2 , MSH6 , PMS2 , BRCA2 , BRCA1 , ATM , CDKN2A , PALB2 , and APC. 20,24–30 Next-generation sequencing analysis of the proband revealed a germline MSH6 missense variant (p.Tyr1066Cys), suggesting its potential role as a susceptibility variant for both IPMN and PC. Because of the highly conserved nature of this tyrosine residue and the large physicochemical differences between tyrosine and cysteine, MSH6 missense variant (p.Tyr1066Cys) is often identified as pathogenic by various in silico pathogenicity prediction tools.…”
