ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0155 (2360/152176) while in subpopulation AFR AF = 0.0345 (1433/41488). AF 95% confidence interval is 0.0331. There are 20 homozygotes in GnomAd4. There are 1174 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High AC in GnomAd4 at 2360 AD gene.
