ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.87).

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00023 (35/152100) while in subpopulation AFR AF = 0.000506 (21/41518). AF 95% confidence interval is 0.000338. There are 0 homozygotes in GnomAd4. There are 20 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 35 AD gene.
