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.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -15 ACMG points.

BP4
?
    BP4 - Multiple lines of computational evidence suggest no impact on gene or gene product (conservation, evolutionary, splicing impact, etc.)
Computational evidence support a benign effect (BayesDel_noAF=-0.83).
BP6
?
    BP6 - Reputable source recently reports variant as benign, but the evidence is not available to the laboratory to perform an independent evaluation
Variant 2-120797329-G-A is Benign according to our data. Variant chr2-120797329-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 697438.Status of the report is criteria_provided_single_submitter, 1 stars.
BP7
?
    BP7 - A synonymous (silent) variant for which splicing prediction algorithms predict no impact to the splice consensus sequence nor the creation of a new splice site AND the nucleotide is not highly conserved
Synonymous conserved (PhyloP=-0.649 with no splicing effect.
BS1
?
    BS1 - Allele frequency is greater than expected for disorder
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.000151 (23/152206) while in subpopulation AMR AF= 0.00124 (19/15294). AF 95% confidence interval is 0.000813. There are 0 homozygotes in gnomad4. There are 11 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
?
    BS2 - Observed in a healthy adult individual for a recessive (homozygous), dominant (heterozygous), or X-linked (hemizygous) disorder, with full penetrance expected at an early age
High AC in GnomAd at 23 AD gene.
