Heterotaxy, visceral, 11, autosomal, with male infertility(HTX11)

MedGen UID:
1794229
Concept ID:
C5562019
Disease or Syndrome
Synonyms: HETEROTAXY, VISCERAL, 11, AUTOSOMAL, WITH MALE INFERTILITY; HTX11
 
Gene (location): CFAP45 (1q23.2)
 
Monarch Initiative: MONDO:0030475
OMIM®: 619608

Definition

Visceral heterotaxy-11 (HTX11) is characterized by a failure to generate normal left-right visceral asymmetry during embryogenesis, which can result in heterotaxy syndrome or situs inversus totalis. Affected individuals may experience mild chronic respiratory symptoms, but do not fulfill the criteria for primary ciliary dyskinesia (see 244400). Male infertility associated with reduced flagellar motility has been reported (Dougherty et al., 2020). For a discussion of genetic heterogeneity of visceral heterotaxy, see HTX1 (306955). [from OMIM]

Clinical features

From HPO
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.
Primum atrial septal defect
MedGen UID:
83374
Concept ID:
C0344735
Congenital Abnormality
An ostium primum atrial septal defect is located in the most anterior and inferior aspect of the atrial septum. The ostium primum refers to an anterior and inferior opening (ostium) within the septum primum, which divides the rudimentary atrium during fetal development. The ostium primum is normally sealed by fusion of the superior and inferior endocardial cushions around 5 weeks' gestation. Ostium primum defects result from a failure of the fusion of the embryologic endocardial cushion and septum primum.
Partial atrioventricular canal
MedGen UID:
868879
Concept ID:
C4023290
Congenital Abnormality
A specific combination of heart defects including a primum atrial septal defect and cleft anterior mitral valve leaflet. There is not an inlet ventricular septal defect present. There are two valve annuluses and two valve orifices.
Situs inversus
MedGen UID:
1642262
Concept ID:
C4551493
Congenital Abnormality
A left-right reversal (or mirror reflection) of the anatomical location of the major thoracic and abdominal organs.
Intestinal malrotation
MedGen UID:
113153
Concept ID:
C0221210
Congenital Abnormality
An abnormality of the intestinal rotation and fixation that normally occurs during the development of the gut. This can lead to volvulus, or twisting of the intestine that causes obstruction and necrosis.
Duodenal atresia
MedGen UID:
75602
Concept ID:
C0266174
Congenital Abnormality
A developmental defect resulting in complete obliteration of the duodenal lumen, that is, an abnormal closure of the duodenum.
Decreased nasal nitric oxide
MedGen UID:
767344
Concept ID:
C3554430
Finding
Reduced level of nasal nitric oxide (nNO). Current American Thoracic Society/European Respiratory Society (ATS/ERS) guidelines for nNO measurements recommend air aspiration via a nasal probe while the subject exhales through the mouth against resistance in order to maintain velum closure.
Chronic sinusitis
MedGen UID:
101751
Concept ID:
C0149516
Disease or Syndrome
A chronic form of sinusitis.
Chronic otitis media
MedGen UID:
75751
Concept ID:
C0271441
Disease or Syndrome
Chronic otitis media refers to fluid, swelling, or infection of the middle ear that does not heal and may cause permanent damage to the ear.
Polysplenia
MedGen UID:
383959
Concept ID:
C1856659
Congenital Abnormality
Polysplenia is a congenital disease manifested by multiple small accessory spleens.
Asthenopia
MedGen UID:
2108
Concept ID:
C0004095
Sign or Symptom
Eye strain, i.e., a feeling of fatigue or discomfort of the eyes related to 'overuse' of the eyes in activities such as reading or working at the computer and often accompanied by lacrimation or headache.
