A syndrome characterized mainly by obesity, pigmentary retinopathy, polydactyly, mental retardation, hypogonadism, and renal failure in fatal cases. Two forms have been identified: Bardet-Biedl syndrome 1 (BBS1) has no linkage to chromosome 16 Bardet-Biedl syndrome 2 (BBS2) is mapped to markers on chromosome 16. Laurence-Moon-Biedl syndrome and Laurence-Moon-Biedl-Bardet syndrome are no longer considered as valid terms in that patients of Laurence and Moon had paraplegia but no polydactyly and obesity which are the key elements of the Bardet-Biedl the syndrome. Laurence-Moon syndrome is a separate entity. - (Source - Diseases Database)
