Genes affected
CNPY3 (HGNC:11968): (canopy FGF signaling regulator 3) This gene encodes a protein that binds members of the toll-like receptor protein family and functions as a chaperone to aid in folding and export of these proteins. Alternative splicing results in multiple transcript variants. Naturally occuring readthrough transcription occurs between this locus and the downstream GNMT (glycine N-methyltransferase) gene and is represented with GeneID:107080644.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.15779218).
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0000591 (9/152200) while in subpopulation NFE AF = 0.000103 (7/68036). AF 95% confidence interval is 0.0000476. There are 0 homozygotes in GnomAd4. There are 6 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
