Genes affected

ITGA2-AS1 (HGNC:40306): (ITGA2 antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0308 (4697/152318) while in subpopulation NFE AF= 0.0341 (2316/68016). AF 95% confidence interval is 0.0329. There are 87 homozygotes in gnomad4. There are 2359 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 87 gene
