Spermatogenic failure-19 (SPGF19) is characterized by multiple morphologic abnormalities of the flagella (MMAF), including absent, short, coiled, bent, and irregular-caliber flagella (Tang et al., 2017).
For a general phenotypic description and a discussion of genetic heterogeneity of spermatogenic failure, see SPGF1 (258150). [from
