ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.97).
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00616 (897/145502) while in subpopulation AFR AF= 0.021 (849/40400). AF 95% confidence interval is 0.0198. There are 15 homozygotes in gnomad4. There are 424 alleles in male gnomad4 subpopulation. Median coverage is 21. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 14 gene
