ACMG classification

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

• BP4: Computational evidence support a benign effect (MetaRNN=0.044445455).
• BS1: Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.00000821 (12/1461892) while in subpopulation AMR AF = 0.000201 (9/44724). AF 95% confidence interval is 0.000104. There are 0 homozygotes in GnomAdExome4. There are 5 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
