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 GLI3 p.Pro707Ser variant was identified in the literature in one of two patients with Greig cephalopolysyndactyly syndrome (Wild_1997_PMID:9302279). The variant was identified in dbSNP (ID: rs121917716), ClinVar (classified as a VUS by Invitae and Genetic Services Laboratory at University of Chicago, as likely pathogenic by Clinical Genetics at Erasmus University Medical Center and as likely benign by Gharavi Laboratory at Columbia University), Cosmic (FATHMM prediction: pathogenic; score=0.97) and LOVD 3.0 (classified as a VUS, likely pathogenic and pathogenic). The variant was also identified in control databases in 73 of 282622 chromosomes at a frequency of 0.000258 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: European (non-Finnish) in 65 of 128924 chromosomes (freq: 0.000504), Other in 2 of 7228 chromosomes (freq: 0.000277), Latino in 5 of 35440 chromosomes (freq: 0.000141) and African in 1 of 24970 chromosomes (freq: 0.00004), but was not observed in the Ashkenazi Jewish, East Asian, European (Finnish) or South Asian populations. The p.Pro707 residue is conserved across mammals and other organisms, and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) suggest that the variant may impact the protein; however, this information is not predictive enough to assume pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
