Spermatogenic failure 41(SPGF41)

MedGen UID:
1684739
•Concept ID:
C5231455
•
Disease or Syndrome
Synonyms: SPERMATOGENIC FAILURE 41; SPGF41
 
Gene (location): CFAP70 (10q22.2)
 
Monarch Initiative: MONDO:0032863
OMIM®: 618670

Definition

Spermatogenic failure-41 (SPGF41) is characterized by infertility due to multiple morphologic abnormalities of the flagella (MMAF). Patient semen analysis has also shown oligozoospermia, and the flagellar abnormalities include short, absent, coiled, and irregular-caliber flagella. Some sperm show tapered heads and acrosomal abnormalities (Beurois et al., 2019). For a discussion of genetic heterogeneity of spermatogenic failure, see SPGF1 (258150). [from OMIM]
