Primary ciliary dyskinesia-14 (CILD14) is an autosomal recessive disorder characterized by recurrent respiratory infections associated with defects in ciliary inner dynein arms and axonemal disorganization (Merveille et al., 2011). For a general phenotypic description and a discussion of genetic heterogeneity of primary ciliary dyskinesia, see CILD1 (244400).

Autosomal visceral heterotaxy-7 is an autosomal recessive developmental disorder characterized by complex congenital heart malformations and/or situs inversus and caused by defects in the normal left-right asymmetric positioning of internal organs. The phenotype is variable (summary by Guimier et al., 2015). For a discussion of the genetic heterogeneity of visceral heterotaxy, see HTX1 (306955).

Primary ciliary dyskinesia-44 (CILD44) is an autosomal recessive disorder characterized by recurrent sinopulmonary infections resulting from defective mucociliary clearance. Affected individuals have onset of symptoms in infancy or early childhood, and the repetitive nature of the disorder results in bronchiectasis. Although respiratory epithelial cell motile cilia are shorter than normal and overall ciliary motion is decreased, nasal nitric oxide, radial ciliary structure, and ciliary beat frequency are normal. In addition, patients do not have situs inversus (summary by Chivukula et al., 2020). For a phenotypic description and a discussion of genetic heterogeneity of primary ciliary dyskinesia, see CILD1 (244400).

Diets-Jongmans syndrome (DIJOS) is an autosomal dominant disorder characterized by mild to moderately impaired intellectual development with a recognizable facial gestalt (summary by Diets et al., 2019).
