Finally, within the non-seminoma networks, the module yellow(NS) contained the eigengene NARS2, which has previously been identified as a TGCT susceptibility gene through GWAS within the cytogenetic band 11q14.1 9 and is also involved in ovarian serous cystadenocarcinomas as a possible progression associated gene57. Here, NARS2 is linked to ovarian serous cystadenocarcinoma.
