[Bardet Biedl syndrome: a case report].

Bardet Biedl syndrome is an autosomal recessive ciliopathie. It is a pleiotropic disorder characterised by retinal dystrophy, renal dysfunction, polydactyly, obesity, cognitive deficit and hypogenitalism. Diagnosis is based on clinical features. Molecular genetic testing is available. There is no specific treatment, a multidisciplinary approach is required. We report the case of a 13-year-old female patient with obesity and hyperphagia, type 2 diabetes, hypothyroidism, polydactyly, cognitive deficit and visual impairment. A multigenic panel allowed the identification of two heterozygous pathogenic variants in the BBS2 gene.
