ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0031599104).

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000866 (132/152360) while in subpopulation SAS AF = 0.0263 (127/4830). AF 95% confidence interval is 0.0226. There are 2 homozygotes in GnomAd4. There are 96 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 2 AR gene
