NM_006586.5:c.243C>G

Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4BS1_Supporting

The NM_006586.5(CNPY3):​c.243C>G​(p.Asp81Glu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000682 in 1,613,942 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D81Y) has been classified as Uncertain significance.

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 -2 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.2715732).
BS1
Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.00000616 (9/1461814) while in subpopulation MID AF = 0.000348 (2/5750). AF 95% confidence interval is 0.0000611. There are 0 homozygotes in GnomAdExome4. There are 3 alleles in the male GnomAdExome4 subpopulation. Median coverage is 30. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
