An exceedingly rare genetic neurological and developmental disorder reported in a very small number of patients with a poorly defined phenotype including iris coloboma, short stature, obesity, hypogonadism, post axial polydactyly, and intellectual disability. Hydrocephalus and facial dysostosis were also reported. The syndrome shares features with Bardet-Biedl syndrome. There have been no new descriptions in the literature since 1997. [from
