ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (MetaRNN=0.12156206).
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.000125 (19/152276) while in subpopulation NFE AF= 0.000265 (18/68026). AF 95% confidence interval is 0.000171. There are 0 homozygotes in gnomad4. There are 10 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
