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.

ACMG classification

Our verdict: Benign. The variant received -9 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
• BP6: Variant 7-41961664-C-T is Benign according to our data. Variant chr7-41961664-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 360165.
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00138 (210/152176) while in subpopulation NFE AF = 0.00243 (165/67942). AF 95% confidence interval is 0.00213. There are 0 homozygotes in GnomAd4. There are 98 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
