Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 4P and 4B. PM5PP3_ModerateBS2

The ENST00000361492.9(GLI2):c.1384C>T(p.Arg462Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000434 in 1,614,110 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R462G) has been classified as Pathogenic.

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.

Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Apr 08, 2022	Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; A different missense change at this residue (p.R479G, reported as p.R151G using alternate nomenclature) has been reported in the published literature in an individual with cleft lip and palate, dysmorphic features, and mild gyral asymmetry on head imaging, but the variant was inherited from an unaffected parent (Richieri-Costa and Ribeiro, 2006; Rahimov et al., 2006); Has not been previously published as pathogenic or benign to our knowledge -
