A recent array-wide methylation analysis conducted on sperm DNA from a cohort of males identified a number of genes associated with infertility, including the maternally imprinted genes DLG associated protein 2 (DLGAP2) and GATA binding protein 3 as well as the paternally imprinted genes catenin alpha 3, membrane-associated guanylate kinase, and tumor protein 73 (Sujit et al., 2018). The gene discussed is DLGAP2; the disease is Infertility.
