CERKL and BBS5 which cause autosomal recessive RP and Bardet-Biedl syndrome, respectively,[14,15]KLHL23, which has strong similarities with the recently described gene KLHL7 responsible for adRP,[16]NEUROD1 which regulates development and maintenance in the visual system[17] and the splicing factor SF3B1[18]. Here, KLHL7 is linked to Bardet-Biedl syndrome.
