Genes affected
SMO (HGNC:11119): (smoothened, frizzled class receptor) The protein encoded by this gene is a G protein-coupled receptor that interacts with the patched protein, a receptor for hedgehog proteins. The encoded protein tranduces signals to other proteins after activation by a hedgehog protein/patched protein complex. [provided by RefSeq, Jul 2010]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.15514883).
BP6
Variant 7-129212264-G-A is Benign according to our data. Variant chr7-129212264-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 135263.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, not_provided=1, Uncertain_significance=1}.
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.000729 (111/152212) while in subpopulation NFE AF= 0.00132 (90/68036). AF 95% confidence interval is 0.0011. There are 1 homozygotes in gnomad4. There are 56 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
