ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.95).
• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.000755 (115/152336) while in subpopulation EAS AF= 0.0187 (97/5180). AF 95% confidence interval is 0.0157. There are 1 homozygotes in gnomad4. There are 62 alleles in male gnomad4 subpopulation. Median coverage is 34. This position pass quality control queck.
