Genes affected

GLI1 (HGNC:4317): (GLI family zinc finger 1) This gene encodes a member of the Kruppel family of zinc finger proteins. The encoded transcription factor is activated by the sonic hedgehog signal transduction cascade and regulates stem cell proliferation. The activity and nuclear localization of this protein is negatively regulated by p53 in an inhibitory loop. Multiple transcript variants encoding different isoforms have been found for this gene.

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM1: In a zinc_finger_region C2H2-type 2 (size 27) in uniprot entity GLI1_HUMAN there are 4 pathogenic changes around while only 0 benign (100%) in NM_005269.3
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.895
• PP5: Variant 12-57466293-G-T is Pathogenic according to our data. Variant chr12-57466293-G-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 2429115.We mark this variant Likely_pathogenic, oryginal submissions are: {Uncertain_significance=1, Likely_pathogenic=1}. Variant chr12-57466293-G-T is described in Lovd as [Pathogenic].
