Variant summary

Our verdict is Uncertain significance. Variant got 5 ACMG points: 6P and 1B. PM2PM5PP3_ModerateBS1_Supporting

The NM_005631.5(SMO):​c.1417G>A​(p.Asp473Asn) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000161 in 1,613,930 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as not provided (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D473H) has been classified as Pathogenic.

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 Uncertain_significance. Variant got 5 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr7-129209348-G-C is described in ClinVar as [Pathogenic]. Clinvar id is 375938.Status of the report is no_assertion_criteria_provided, 0 stars.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.871
BS1
Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.0000171 (25/1461794) while in subpopulation EAS AF= 0.000403 (16/39700). AF 95% confidence interval is 0.000252. There are 0 homozygotes in gnomad4_exome. There are 17 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
