Additionally, other DNAHs, such as DNAH1, DNAH2, DNAH8, DNAH10, DNAH12, and DNAH17, are suggested to be pathogenic genes of isolated male infertility (Ben Khelifa et al., 2014; Hwang et al., 2021; Liu et al., 2020; Li et al., 2021; Whitfield et al., 2019). The gene discussed is DNAH2; the disease is male infertility.
