Spermatogenic failure 27(SPGF27)

MedGen UID:: 1634748
•Concept ID:: C4693784
•: Disease or Syndrome

Synonyms:	SPERMATOGENIC FAILURE 27; SPGF27

Gene (location): Gene(s) directly associated with this condition or phenotype.	AK7 (14q32.2)

Monarch Initiative:	MONDO:0054731
OMIM®:	617965

Definition

Spermatogenic failure-27 (SPGF27) is characterized by infertility due to multiple morphologic abnormalities of the sperm flagella (MMAF), a phenotype also designated as 'dysplasia of the fibrous sheath,' 'short tails,' or 'stump tails.' Spermatozoa in the ejaculate exhibit short, irregular, coiled, or absent flagella. Ultrastructural analysis shows loss of the central pair of microtubules, loss of the inner dynein arms, and peripheral doublet disorganization (Lores et al., 2018). For a discussion of the phenotypic and genetic heterogeneity of spermatogenic failure, see SPGF1 (258150). [from OMIM]

Clinical features

From HPO

Male infertility

MedGen UID:: 5796
•Concept ID:: C0021364
•: Disease or Syndrome

Absent sperm axoneme central pair complex

MedGen UID:: 1785608
