ABSTRACT

Abstract: Cystic fibrosis - one of the most common monogenic diseases in the world, is inherited by an autosomalrecessive type and is caused by mutations in the CFTR gene, the product of which is a cAMP-dependent chlorine channel.By now, there are more than 2,000 mutations in this gene that are divided into classes depending on protein damage,highlighting "heavy" and "soft" mutations in their effect on the severity of exocrine pancreatic insufficiency. However, thereis still no clear association between the genotype and the clinical manifestation of cystic fibrosis, such as hepato-biliarypathology, in particular cirrhosis. In connection with this, the purpose of this study was to study the clinical and geneticfeatures of connective tissue dysplasia syndrome in children with cystic fibrosis, to assess the possible modifying effect ofpolymorphisms of connective tissue genes on the development of fibrosis / cirrhosis in cystic fibrosis. The study included188 children from 3 to 17 years (median 10 years) with a diagnosis of cystic fibrosis. A statistically significant association ofMMP3 polymorphisms and severe clinical manifestations on the part of the hepato-biliary system (classification of СhayldPew) was revealed.
