INTS13 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00995 (1500/150724) while in subpopulation AFR AF= 0.0341 (1409/41282). AF 95% confidence interval is 0.0326. There are 26 homozygotes in gnomad4. There are 657 alleles in male gnomad4 subpopulation. Median coverage is 30. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 26 gene
