ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0068519413).
• BP6: Variant 10-79942454-G-C is Benign according to our data. Variant chr10-79942454-G-C is described in ClinVar as [Benign]. Clinvar id is 165216.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0265 (4026/152196) while in subpopulation AMR AF= 0.0451 (690/15288). AF 95% confidence interval is 0.0423. There are 87 homozygotes in gnomad4. There are 1913 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 87 AR gene
