ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.019890577).
BS1
Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.0000557 (78/1399414) while in subpopulation NFE AF = 0.0000686 (74/1078968). AF 95% confidence interval is 0.0000559. There are 0 homozygotes in GnomAdExome4. There are 39 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High AC in GnomAdExome4 at 78 AD gene.
