Genes affected

ERI2 (HGNC:30541): (ERI1 exoribonuclease family member 2) Predicted to enable 3'-5'-exoribonuclease activity. Predicted to be involved in exonucleolytic trimming to generate mature 3'-end of 5.8S rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA). [provided by Alliance of Genome Resources, Apr 2022]

ERI2 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=2.2722978E-5).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.578 is higher than 0.05.
