Although mental retardation has been considered part of the BBS phenotype, several patients with BBS3 and normal intelligence have been reported. Additionally, the obesity in several BBS3 patients has been reversible with caloric restriction and exercise ({8:Young et al., 1998}; {5:Ghadami et al., 2000}).\\n\\nFor a general phenotypic description and a discussion of genetic heterogeneity of Bardet-Biedl syndrome, see BBS1 ({209900}).","GARD_Name__c":"Bardet-Biedl syndrome 3","GARD_Synonym__c":"bardet-biedl syndrome type 3; bbs3","Curated_Disease_Description_Source__c":"MEDGEN:C1859564","Curated_Disease_Description__c":"Bardet-Biedl syndrome (BBS) is characterized by rod-cone dystrophy, truncal obesity, postaxial polydactyly, cognitive impairment, male hypogonadotropic hypogonadism, complex female genitourinary malformations, and renal abnormalities.
