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.

Pallister-Hall syndrome;C0265306:Greig cephalopolysyndactyly syndrome Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 27, 2018This variant is not present in population databases (ExAC no frequency). For these reasons, this variant has been classified as Pathogenic. This variant disrupts the C-terminus of the GLI3 protein. Other variant(s) that disrupt this region (p.Thr1488Lysfs*23) have been determined to be pathogenic (PMID: 24736735). This suggests that variants that disrupt this region of the protein are likely to be causative of disease. Experimental studies and prediction algorithms are not available for this variant, and the functional significance of the affected amino acid(s) is currently unknown. This variant has not been reported in the literature in individuals with GLI3-related conditions. ClinVar contains an entry for this variant (Variation ID: 38326). This sequence change results in a premature translational stop signal in the GLI3 gene (p.Gln1161*). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 420 amino acids of the GLI3 protein. -
