The variant allele was found at a frequency of 0.134 in 152,052 control chromosomes in the GnomAD database, including 1,616 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.13 (1616 hom., cov: 33)
• Consequence: UBAC2 NM_001144072.2 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.549

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

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.45).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.309 is higher than 0.05.
