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

Verdict is Benign. Variant got -16 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BP6: Variant 7-42023625-G-C is Benign according to our data. Variant chr7-42023625-G-C is described in ClinVar as [Likely_benign]. Clinvar id is 255421.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr7-42023625-G-C is described in Lovd as [Likely_benign].
• BS2: High AC in GnomAd4 at 384 AD gene.
