Summaries for Spermatogenic Failure 20

OMIM : 57 Spermatogenic failure-20 is characterized by multiple morphologic abnormalities of the flagella, 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). (617593)

MalaCards based summary : Spermatogenic Failure 20, is also known as spgf20. An important gene associated with Spermatogenic Failure 20 is CFAP44 (Cilia And Flagella Associated Protein 44).

UniProtKB/Swiss-Prot : 75 Spermatogenic failure 20: An infertility disorder caused by spermatogenesis defects and characterized by abnormally shaped spermatozoa in the semen of affected individuals. SPGF20 patients have spermatozoa with absent, short, coiled, bent, and/or irregular-caliber flagella, which impair sperm motility.
