Genes affected

EDEM3 (HGNC:16787): (ER degradation enhancing alpha-mannosidase like protein 3) Quality control in the endoplasmic reticulum (ER) ensures that only properly folded proteins are retained in the cell through recognition and degradation of misfolded or unassembled proteins. EDEM3 belongs to a group of proteins that accelerate degradation of misfolded glycoproteins in the ER (Hirao et al., 2006 [PubMed 16431915]).[supplied by OMIM, Mar 2008]

EDEM3 Gene-Disease associations (from GenCC):

• congenital disorder of glycosylation, type 2v

  Inheritance: AR Classification: STRONG Submitted by: ClinGen, G2P, Labcorp Genetics (formerly Invitae)

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.2109021).
