ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP6: Variant 6-79485887-TCAA-T is Benign according to our data. Variant chr6-79485887-TCAA-T is described in ClinVar as [Benign]. Clinvar id is 1879667.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00699 (1065/152300) while in subpopulation NFE AF= 0.0101 (686/68008). AF 95% confidence interval is 0.00946. There are 8 homozygotes in gnomad4. There are 550 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 8 AR gene
