ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.02872321).
BS1
Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.00826 (11438/1384256) while in subpopulation MID AF= 0.0372 (212/5696). AF 95% confidence interval is 0.0331. There are 71 homozygotes in gnomad4_exome. There are 5560 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 13 AR gene
