Genes affected

DYNLRB2-AS1 (HGNC:55405): (DYNLRB2 antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.97).
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0115 (1755/152076) while in subpopulation AFR AF= 0.0403 (1670/41470). AF 95% confidence interval is 0.0387. There are 30 homozygotes in gnomad4. There are 825 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 30 gene
