Promoter methylation of candidate genes associated with familial testicular cancer.

ABSTRACT: Recent genomic studies have identified risk SNPs in or near eight genes associated with testicular germ cell tumors (TGCT). Mouse models suggest a role for Dnd1 epigenetics in TGCT susceptibility, and we have recently reported that transgenerational inheritance of epigenetic events may be associated with familial TGCT risk. We now investigate whether aberrant promoter methylation of selected candidate genes is associated with familial TGCT risk. Pyrosequencing assays were designed to evaluate CpG methylation in the promoters of selected genes in peripheral blood DNA from 153 TGCT affecteds and 116 healthy male relatives from 101 multiple-case families. Wilcoxon rank-sum tests and logistic regression models were used to investigate associations between promoter methylation and TGCT. We also
