Genes affected

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=-0.88).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.604 is higher than 0.05.
