ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -8 ACMG points.

BS1

Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.00513 (782/152314) while in subpopulation EAS AF = 0.0523 (271/5184). AF 95% confidence interval is 0.0472. There are 6 homozygotes in GnomAd4. There are 412 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 6 AR gene
