PARTICIPATING COUNTRY: Germany

TREATMENT: Not applicable

PRIMARY OBJECTIVE: To investigate the prevalence of BBS in an at-risk population

SECONDARY OBJECTIVES:

* To explore genotype-phenotype correlation
* To assess genotypes distribution in Germany and compare to other countries
* To identify new genes/variants
* To investigate clinical characteristics in individuals diagnosed with BBS
