ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 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. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High Homozygotes in GnomAd4 at 6 AR gene
