Genes affected
GLI3 (HGNC:4319): (GLI family zinc finger 3) This gene encodes a protein which belongs to the C2H2-type zinc finger proteins subclass of the Gli family. They are characterized as DNA-binding transcription factors and are mediators of Sonic hedgehog (Shh) signaling. The protein encoded by this gene localizes in the cytoplasm and activates patched Drosophila homolog (PTCH) gene expression. It is also thought to play a role during embryogenesis. Mutations in this gene have been associated with several diseases, including Greig cephalopolysyndactyly syndrome, Pallister-Hall syndrome, preaxial polydactyly type IV, and postaxial polydactyly types A1 and B.

The c.1474G>A (p.D492N) alteration is located in exon 10 (coding exon 9) of the GLI3 gene. This alteration results from a G to A substitution at nucleotide position 1474, causing the aspartic acid (D) at amino acid position 492 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
