Bardet-Biedl Syndrome (BBS12-Related) (BBS12)

Bardet-Biedl syndrome (BSS12-related) is an autosomal recessive, pan-ethnic disease with symptoms including rod-cone dystrophy, truncal obesity, postaxial polydactyly, cognitive impairment, male hypogonadotrophic hypogonadism, complex female genitourinary malformations, and renal abnormalities. Individuals experience night blindness by childhood and are diagnosed with legal blindness by an average age of 15 years. While most patients are expected to survive into adulthood, earlier death may occur when renal disease is severe. No genotype-phenotype correlation has been reported.
