ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.0024843216).
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0125 (1899/152248) while in subpopulation AFR AF= 0.0435 (1806/41522). AF 95% confidence interval is 0.0418. There are 33 homozygotes in gnomad4. There are 905 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High Homozygotes in GnomAd4 at 33 AR gene
