ACMG classification

Our verdict: Benign. The variant received -8 ACMG points.

• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00995 (1500/150724) while in subpopulation AFR AF = 0.0341 (1409/41282). AF 95% confidence interval is 0.0326. There are 26 homozygotes in GnomAd4. There are 657 alleles in the male GnomAd4 subpopulation. Median coverage is 30. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 26 gene
