Spermatogenic failure, X-linked, 6(SPGFX6)

MedGen UID:
1840198
Concept ID:
C5829562
Disease or Syndrome
Synonym: SPGFX6
 
Gene (location): USP26 (Xq26.2)
 
Monarch Initiative: MONDO:0859478
OMIM®: 301101

Definition

X-linked spermatogenic failure-6 (SPGFX6) is characterized by male infertility due to asthenoteratozoospermia. Patient spermatozoa show reduced progressive motility, and multiple morphologic abnormalities of the flagella (MMAF) are observed, primarily short and coiled flagella. Pregnancy can be achieved by intracytoplasmic sperm injection (ICSI) (Liu et al., 2021). For a general phenotypic description and discussion of 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
The inability of the male to effect fertilization of an ovum after a specified period of unprotected intercourse. Male sterility is permanent infertility.
Abnormal male external genitalia morphology
MedGen UID:
871399
Concept ID:
C4025897
Anatomical Abnormality
Any structural abnormality of male external genitalia.
Reduced sperm motility
MedGen UID:
907698
Concept ID:
C4082176
Finding
An abnormal reduction in the mobility of ejaculated sperm.
Short sperm flagella
MedGen UID:
1623693
Concept ID:
C4539787
Finding
Sperm cells with abnormally short flagella.
Coiled sperm flagella
MedGen UID:
1611216
Concept ID:
C4539789
Finding
Sperm cells whose flagella are twisted (coiled).
Microcephalic sperm head
MedGen UID:
1640115
Concept ID:
C4693760
Finding
Decreased size of the head of sperm.
Reduced progressive sperm motility
MedGen UID:
1730031
Concept ID:
C5436680
Finding
A reduced proportion of sperm that move in a straight line or large circles; alternatively, an increased proportion of sperm that move in tight circles or in some other non-linear fashion.
Absent sperm axoneme central pair complex
MedGen UID:
1785608
Concept ID:
C5539658
Finding
Absence of the central pair of microtubules in the sperm axoneme, thereby forming a 9+0 pattern instead of the normal 9+2 pattern.
Recurrent pneumonia
MedGen UID:
195802
Concept ID:
C0694550
Disease or Syndrome
An increased susceptibility to pneumonia as manifested by a history of recurrent episodes of pneumonia.
Recurrent bronchitis
MedGen UID:
148159
Concept ID:
C0741796
Disease or Syndrome
An increased susceptibility to bronchitis as manifested by a history of recurrent bronchitis.
Recurrent otitis media
MedGen UID:
155436
Concept ID:
C0747085
Disease or Syndrome
Increased susceptibility to otitis media, as manifested by recurrent episodes of otitis media.
