ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -10 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.3).

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0238 (3591/151160) while in subpopulation NFE AF = 0.0366 (2475/67654). AF 95% confidence interval is 0.0354. There are 69 homozygotes in GnomAd4. There are 1707 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 3591 AD gene.
