Hypothalamic hamartomaNon-enhancing mass in the floor of the third ventricle posterior to the optic chiasm
Mesoaxial polydactylyPresence of six or more well-formed digits with a “Y”-shaped metacarpal or metatarsal bone
Post axial polydactyly (PAP)PAP-A is the presence of a well-formed digit on the ulnar or fibular aspect of the limb. PAP-B is the presence of a rudimentary digit or nubbin in the same location
