Intellectual disability-spasticity-ectrodactyly syndrome, also known as Jancar syndrome,[1][2] is a rare autosomal recessive genetic disorder which is characterized by severe intellectual disabilities, hereditary spastic paraplegia, and defects of the distal limbs, such as syndactyly, ectrodactyly, and clinodactyly.[3][4] Only 3 families in England and Israel have been described in medical literature.[5][6][7][8]
