ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -6 ACMG points.

PP3

Splicing predictors support a deleterious effect. Scorers claiming Pathogenic: max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0226 (3428/151888) while in subpopulation AFR AF = 0.0266 (1106/41524). AF 95% confidence interval is 0.0253. There are 39 homozygotes in GnomAd4. There are 1639 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 39 gene
