ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0145 (2212/152294) while in subpopulation SAS AF= 0.0442 (213/4824). AF 95% confidence interval is 0.0393. There are 29 homozygotes in gnomad4. There are 1108 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 29 gene
