Gene Family: Bardet-Biedl syndrome associated (BBS)

Bardet-Biedl syndrome: The Bardet-Biedl syndrome (BBS) is a ciliopathic human genetic disorder that produces many effects and affects many body systems. It is characterized principally by obesity, retinitis pigmentosa, polydactyly, hypogonadism, and renal failure in some cases. Historically, mental retardation has been considered a principal symptom but is now not regarded as such. [Source: Wikipedia]

This page lists all of the genes currently known to be causative for Bardet-Biedl syndrome. A subset of these genes encode the subunits of the BBSome (BBS1, BBS2, BBS4, BBS5, BBS7, BBS8, BBS9, and BBIP1), a multisubunit complex involved in ciliary trafficking and membrane biogenesis. Three further BBS genes (BBS6, BBS10 and BBS12) are homologous to type II chaperonins and together with CCT proteins and BBS7 form the BBS-chaperonin complex which is required for BBSome assembly.
