[Two cases of skeletal ciliopathies in one family].

Abstract

Cilia are thin extensions on the cells of eukaryotic organisms. They are formed by a special protein transport mechanism - the intraflagellar transporter (IFT). The IFT consists of two proteins: complex A and complex B. Mutations in the genes of the IFT-A complex (IFT43, IFT121, IFT122, IFT139, IFT140, and IFT144) lead to the development of skeletal ciliopathies. These include Sensenbrenner, Jeune, and short-rib polydactyly syndrome [1,2]. We report two cases of different ciliopathies in a non-related family; both parents are heterozygous carriers of a pathogenic mutation in the IFT122 gene.
