ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.003202647).

BS1

Variant frequency is greater than expected in population afr. gnomad4_exome allele frequency = 0.000599 (876/1461728) while in subpopulation AFR AF= 0.0183 (611/33476). AF 95% confidence interval is 0.0171. There are 7 homozygotes in gnomad4_exome. There are 396 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck.

BS2

High Homozygotes in GnomAd4 at 8 AR gene
