The gene on chromosome 7p13 that encodes GLI family zinc finger protein 3 (OMIM: 165240, UniProtKB: P10071), a DNA-binding C2H2-type zinc finger protein of the Gli family, which plays a role in limb development. The Gli family are DNA-binding transcription factors and mediate Sonic hedgehog (Shh) signaling. The full length GLI3–GLI3FL is a transcriptional activator; GLI3R, the C-terminally truncated form represses the Shh pathway.

Molecular pathology Defects of GLI3 cause:

• Greig cephalopolysyndactyly syndrome (OMIM:175700)

• Pallister-Hall syndrome 1 (OMIM:146510)

• Preaxial polydactyly 4 (OMIM:174700)

• Postaxial polydactyly A1 (OMIM:174200)

• Postaxial polydactyly B (OMIM:174200)
