Spermatogenic failure 79(SPGF79)

MedGen UID:
1824063
•Concept ID:
C5774290
•
Disease or Syndrome
Synonym: SPGF79
 
Gene (location): KCNU1 (8p11.23)
 
Monarch Initiative: MONDO:0859352
OMIM®: 620196

Definition

Spermatogenic failure-79 (SPGF79) is characterized by male infertility due to an abnormal acrosome reaction and impaired membrane potential after capacitation. Some patients exhibit asthenoteratozoospermia, with defective acrosome formation and mitochondrial sheath assembly, and reduced progressive motility (Lv et al., 2022; Liu et al., 2022). For a general phenotypic description and discussion of genetic heterogeneity of spermatogenic failure, see SPGF1 (258150). [from OMIM]
