Genetic Characterization of a Model Ciliopathy: Bardet–Biedl Syndrome

Bardet-Biedl syndrome (BBS) is a rare ciliopathy affecting multiple organ systems. Patients with BBS are usually diagnosed later in childhood when clinical features of the disease become apparent. In this article, we presented a case of BBS discovered by whole genome sequencing in a newborn with heterotaxy, duodenal atresia, and complex congenital heart disease. Early diagnosis is important not only for prognostication but also to explore ways to mitigate the cone-rod dysfunction and for exploring newer therapies. Our case highlights the importance of a high index of suspicion and the utility of advanced genetic testing to provide an early diagnosis for a rare disease.
