Greig Cephalopolysyndactyly Syndrome

Greig cephalopolysyndactyly syndrome (GCPS) is a congenital disorder that affects development of the limbs, head, and face. Findings might include an extra finger or toe (polydactyly), fusion of the skin between the fingers or toes (syndactyly), widely spaced eyes (ocular hypertelorism), and an abnormally large head size (macrocephaly).The features of this syndrome are highly variable, ranging from polydactyly and syndactyly of the upper and/or lower limbs to seizure, hydrocephalus , and intellectual disability. Progression of GCPS is dependent on severity. Greig cephalopolysyndactyly syndrome is caused by mutations in the GLI3 gene. This condition is inherited in an autosomal dominant pattern. Treatment is symptomatic.
