We observed one gene (ADAP1) that was hypermethylated in both germinomas/seminomas/dysgerminoma and YST (both β > 0.7) and 22 genes (results not shown) that were hypomethylated in both germinomas/seminomas/dysgerminoma and YST (both β < 0.3); four of these still reached our threshold as DMRs (differential β > 0.2), but did not meet the threshold for inclusion in the pathway analysis. Here, ADAP1 is linked to germinoma.
