Bardet-Biedl Syndrome
摘要
Bardet-Biedl syndrome (BBS) is an autosomal recessive pleiotropic ciliopathy caused by biallelic (likely) pathogenetic variants in genes associated with BBS. Truncal obesity is present in around 89% of patients and usually begins in the first year of life. Other main characteristics include retinal dystrophy, genital and renal anomalies, polydactyly and learning disabilities.
