Clinical and genetic characteristics of genetic skeletal disorders

Abstract

The effectiveness of DNA analysis for diagnostics of genetic skeletal disorders (GSD) based on the investigation of the data of 270 Russian patients was evaluated. The usage of various molecular genetic methods allows to clarify the diagnosis in 74% of patients with clinical and radiological signs of systemic skeletal disorders. The incidence of 8 most common groups of NSD was calculated. It has been shown that the most commonly diagnosed conditions included FGFR3-relared chondrodysplasias, collagenopathies and diseases caused by impaired sulfate metabolism, which account for 67.5% of all diagnosed NSD.
