Genes affected

GPR183 (HGNC:3128): (G protein-coupled receptor 183) This gene was identified by the up-regulation of its expression upon Epstein-Barr virus infection of primary B lymphocytes. This gene is predicted to encode a G protein-coupled receptor that is most closely related to the thrombin receptor. Expression of this gene was detected in B-lymphocyte cell lines and lymphoid tissues but not in T-lymphocyte cell lines or peripheral blood T lymphocytes. The function of this gene is unknown.

UBAC2 (HGNC:20486): (UBA domain containing 2) Involved in negative regulation of canonical Wnt signaling pathway and negative regulation of retrograde protein transport, ER to cytosol. Acts upstream of or within protein localization to endoplasmic reticulum. Located in endoplasmic reticulum. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.93).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.216 is higher than 0.05.
