<unk>  is an autosomal recessive congenital disorder characterized by mental retardation, truncal obesity, retinal dystrophy, and micropenis". The disorder shares similar characteristics with Bardet–Biedl syndrome and Cohen syndrome, both of which are autosomal recessive genetic disorders.<unk>  can be distinguished from the above disorders because symptoms appear at a young age. The disorder is not dependent on sex of the offspring, both male and female offspring are equally likely to inherit the disorder. The syndrome is caused by a mutation in the INPP5E gene which can be located on chromosome 9 in humans. Further mapping resulted in the identification of a<unk>  locus on chromosome 9q34.3 between the genetic markers D9S158 and D9S905.
