Primary ciliary dyskinesia in a child with type II Simpson -Golabi - Bemel syndrome due to OFD1 gene mutation

Primary ciliary dyskinesia (PCD) is an orphan disease associated with mutations in several genes. It is a ciliopathy, an abnormality of the cilia and flagella. Ciliopathies include the extremely rare Simpson - Golabi - Bemel syndrome (SSGB) type II.The aim of this article is to familiarize the reader with the possibility of simultaneous presence of type II SSGB and PCD in a patient with bronchiectasis (BE).Results. The first clinical observation in the Russian literature is presented withhistory, physical examination, including clinical and morphologic examination, results of additional investigations and initiation of therapy. The case describes a 15-year-old patient with BE and other lesions typical of PCD confirmed on the basis of structural changes in the cilia of the respiratory epithelium of the trachea detected by transmission electron microscopy. The patient had a pathogenic mutation of the OFD1 gene responsible for the development of both type II SSGB and PCD.Conclusion. Several variants of ciliopathies may occur in one patient, and PCD may present as a syndrome.
