Genes affected

EDEM1 (HGNC:18967): (ER degradation enhancing alpha-mannosidase like protein 1) Enables mannosyl-oligosaccharide 1,2-alpha-mannosidase activity and misfolded protein binding activity. Involved in mannose trimming involved in glycoprotein ERAD pathway; positive regulation of retrograde protein transport, ER to cytosol; and protein targeting to ER. Located in aggresome and endoplasmic reticulum quality control compartment. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.96).
