Ciliary dyskinesia, primary, 36, X-linked(CILD36)

MedGen UID:
1393107
Concept ID:
C4478372
Disease or Syndrome
Synonyms: CILD36; CILIARY DYSKINESIA, PRIMARY, 36, WITH OR WITHOUT SITUS INVERSUS
 
Gene (location): DNAAF6 (Xq22.3)
 
Monarch Initiative: MONDO:0010517
OMIM®: 300991

Definition

CILD36 is an X-linked recessive disorder characterized by chronic airway disease and recurrent sinopulmonary infections beginning in childhood and caused by defective ciliary function. Affected individuals also have infertility due to defective sperm flagella. About half of patients have laterality defects due to ciliary dysfunction at the embryonic node (summary by Paff et al., 2017). For a phenotypic description and a discussion of genetic heterogeneity of primary ciliary dyskinesia, see CILD1 (244400). [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.
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.
Bronchiectasis
MedGen UID:
14234
Concept ID:
C0006267
Disease or Syndrome
Persistent abnormal dilatation of the bronchi owing to localized and irreversible destruction and widening of the large airways.
Cough
MedGen UID:
41325
Concept ID:
C0010200
Sign or Symptom
A sudden, audible expulsion of air from the lungs through a partially closed glottis, preceded by inhalation.
Recurrent sinusitis
MedGen UID:
107919
Concept ID:
C0581354
Disease or Syndrome
A recurrent form of sinusitis.
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.
Recurrent respiratory infections
MedGen UID:
812812
Concept ID:
C3806482
Finding
An increased susceptibility to respiratory infections as manifested by a history of recurrent respiratory infections.
Neonatal respiratory distress
MedGen UID:
924182
Concept ID:
C4281993
Finding
Respiratory difficulty as newborn.
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.
Nasal congestion
MedGen UID:
6523
Concept ID:
C0027424
Sign or Symptom
Reduced ability to pass air through the nasal cavity often leading to mouth breathing.
