ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.034 (5173/152220) while in subpopulation SAS AF= 0.0537 (258/4808). AF 95% confidence interval is 0.0483. There are 152 homozygotes in gnomad4. There are 2470 alleles in male gnomad4 subpopulation. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 153 gene
