Definition
Bardet-Biedl syndrome is a rare autosomal recessive ciliopathy with multisystemic compromise, affecting vision, kidneys, and eventually heart, liver and digestive system. Obesity, mental retardation, hypogonadism and polydactilia are common findings. The prevalence is 1: 100 000. Although near 21 genes have been described, mutations in BBS1 and BBS10 account for the majority of genotypes (51% and 20% respectively)
Why to perform genetic testing in cases with suspected BBS?
- To confirm the diagnosis
- To better perform risk stratification and prognosis
- To select the best therapeutic option for that specific patient based on the genotype
- To identify other relatives at risk to develop the disease
