Spermatogenic failure-72 (SPGF72) is characterized by male infertility due to multiple morphologic abnormalities of the flagella (MMAF), including coiled, short, angulated, absent, and irregular-caliber flagella, resulting in lack of sperm motility (Ni et al., 2020).
For a general phenotypic description and discussion of genetic heterogeneity of spermatogenic failure, see SPGF1 (258150). [from
