ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.26358443).
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0000263 (4/152368) while in subpopulation SAS AF = 0.000827 (4/4834). AF 95% confidence interval is 0.000282. There are 0 homozygotes in GnomAd4. There are 2 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
