Genes affected

GLI2 (HGNC:4318): (GLI family zinc finger 2) This gene encodes a protein which belongs to the C2H2-type zinc finger protein subclass of the Gli family. Members of this subclass are characterized as transcription factors which bind DNA through zinc finger motifs. These motifs contain conserved H-C links. Gli family zinc finger proteins are mediators of Sonic hedgehog (Shh) signaling and they are implicated as potent oncogenes in the embryonal carcinoma cell. The protein encoded by this gene localizes to the cytoplasm and activates patched Drosophila homolog (PTCH) gene expression. It is also thought to play a role during embryogenesis. The encoded protein is associated with several phenotypes- Greig cephalopolysyndactyly syndrome, Pallister-Hall syndrome, preaxial polydactyly type IV, postaxial polydactyly types A1 and B.

Loss-of-function variants in GLI2 are known to be pathogenic (PMID: 14581620, 20685856). For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals with GLI2-related disease. ClinVar contains an entry for this variant (Variation ID:¬†520904). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Ala108Leufs*15) in the GLI2 gene. It is expected to result in an absent or disrupted protein product. -
