Greig cephalopolysyndactyly syndrome

(greg), [MIM*175700]
an autosomal dominant disorder characterized by polysyndactyly of the hands and feet, macrocephaly, frontal bossing, hypertelorism, and flat nasal bridge, caused by mutation in the GLI3 gene on chromosome 7p13.

GLI3

A gene on chromosome 7p13 that encodes a DNA-binding C2H2-type zinc finger protein of the Gli family, which plays a role in limb development. The full-length GLI3 (GLI3FL) is a transcriptional activator; GLI3R, the C-terminally truncated form, acts as a repressor of the sonic hedgehog (Shh) pathway.

Molecular pathology
GLI3 mutations are associated with Greig cephalopolysyndactyly syndrome, Pallister-Hall syndrome, pre-axial polydactyly type IV, and postaxial polydactyly types A1 and B.
