Description : Primary ciliary dyskinesia is a genetically heterogeneous autosomal recessive disorder
resulting from loss of function of different parts of the primary ciliary apparatus,
most often dynein arms. Kartagener (pronounced KART-agayner) syndrome is characterized
by the combination of primary ciliary dyskinesia and situs inversus (270100), and
occurs in approximately half of patients with ciliary dyskinesia. Since normal nodal
ciliary movement in the embryo is required for normal visceral asymmetry, absence
of normal ciliary movement results in a lack of definitive patterning; thus, random
chance alone appears to determine whether the viscera take up the normal or reversed
left-right position during embryogenesis. This explains why approximately 50% of patients,
even within the same family, have situs inversus (Afzelius, 1976; El Zein et al.,
2003). - Genetic Heterogeneity of Primary Ciliary Dyskinesia Other forms of primary
ciliary dyskinesia include CILD2 (606763), caused by mutation in the DNAAF3 gene (614566)
on chromosome 19q13; CILD3 (608644), caused by mutation in the DNAH5 gene (603335)
on 5p; CILD4 (608646) on 15q13; CILD5 (608647), caused by mutation in the HYDIN gene
(610812) on 16q22; CILD6 (610852), caused by mutation in the TXNDC3 gene (607421)
on 7p14-p13; CILD7 (611884), caused by mutation in the DNAH11 gene (603339) on 7p21;
CILD8 (612274) on 15q24-q25; CILD9 (612444), caused by mutation in the DNAI2 gene
(605483) on 17q25; CILD10 (612518), caused by mutation in the KTU gene (612517) on
14q21.3; CILD11 (612649), caused by mutation in the RSPH4A gene (612647) on 6q22;
CILD12 (612650), caused by mutation in the RSPH9 gene (612648) on 6p21; CILD13 (613193),
caused by mutation in the DNAAF1 gene (613190) on 16q24.1; CILD14 (613807), caused
by mutation in the CCDC39 gene (613798) gene on 3q26.33; CILD15 (613808), caused by
mutation in the CCDC40 gene (613799) on 17q25.3; CILD16 (614017), caused by mutation
in the DNAL1 gene (610062) on 14q24.3; CILD17 (614679), caused by mutation in the
