Genes affected

PRSS3 (HGNC:9486): (serine protease 3) This gene encodes a trypsinogen, which is a member of the trypsin family of serine proteases. This enzyme is expressed in the brain and pancreas and is resistant to common trypsin inhibitors. It is active on peptide linkages involving the carboxyl group of lysine or arginine. This gene is localized to the locus of T cell receptor beta variable orphans on chromosome 9. Four transcript variants encoding different isoforms have been described for this gene.

UBE2R2-AS1 (HGNC:49911): (UBE2R2 antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BP6: Variant 9-33797763-G-A is Benign according to our data. Variant chr9-33797763-G-A is described in ClinVar as [Benign]. Clinvar id is 1237663.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAdExome4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.72 is higher than 0.05.
