Genes affected

GRK3-AS1 (HGNC:55679): (GRK3 antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0194 (2949/152262) while in subpopulation AFR AF= 0.0326 (1354/41524). AF 95% confidence interval is 0.0312. There are 44 homozygotes in gnomad4. There are 1394 alleles in male gnomad4 subpopulation. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 43 gene
