For instance, a hypomethylation was observed in CpG sites associated with cancer-related genes: leucine-rich repeat-containing 26 (LRRC26), homeobox B9 (HOXB9), and BR serine/threonine kinase 2 (BRSK2) only in boys, which correlated with an increase in As levels [72]. The gene discussed is BRSK2; the disease is cancer.
