Prenatal diagnosis of Bardet–Biedl syndrome in a case of hyperechogenic kidneys: Clinical use of DNA sequencing

Abstract

Bardet–Biedl syndrome ( BBS ) is a ciliopathy that is responsible for multiple visceral abnormalities. This disorder is defined by a combination of clinical signs, many of which appear after several years of development. BBS may be suspected antenatally based on routine ultrasound findings of enlarged hyperechogenic kidneys and postaxial polydactyly.
