ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.3).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0238 (3591/151160) while in subpopulation NFE AF= 0.0366 (2475/67654). AF 95% confidence interval is 0.0354. There are 69 homozygotes in gnomad4. There are 1707 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 3591 AD gene.
