Spermatogenic failure 38(SPGF38)

MedGen UID:
1680356
•Concept ID:
C5193095
•
Disease or Syndrome
Synonyms: SPERMATOGENIC FAILURE 38; SPGF38
 
Gene (location): ARMC2 (6q21)
 
Monarch Initiative: MONDO:0032748
OMIM®: 618433

Definition

Spermatogenic failure-38 (SPGF38) is characterized by primary infertility and asthenoteratozoospermia due to multiple morphologic abnormalities of the flagella (MMAF). Spermatozoa show total sperm motility below 10% and exhibit morphologic anomalies including short, absent, coiled, bent, or irregular-caliber flagella (Coutton et al., 2019). For a discussion of genetic heterogeneity of spermatogenic failure, see SPGF1 (258150). [from OMIM]

Abnormal axonemal organization of respiratory motile cilia
MedGen UID:
868588
•Concept ID:
C4022987
•
Anatomical Abnormality
Abnormal arrangement of the structures of the axoneme, which is the cytoskeletal structure that forms the inner core of the motile cilium and displays a canonical 9+2 microtubular pattern of motile cilia studded with dynein arms.
