Genes affected

EDEM2 (HGNC:15877): (ER degradation enhancing alpha-mannosidase like protein 2) In the endoplasmic reticulum (ER), misfolded proteins are retrotranslocated to the cytosol and degraded by the proteasome in a process known as ER-associated degradation (ERAD). EDEM2 belongs to a family of proteins involved in ERAD of glycoproteins (Mast et al., 2005 [PubMed 15537790]).[supplied by OMIM, Mar 2008]

The c.1450G>A (p.A484T) alteration is located in exon 11 (coding exon 11) of the EDEM2 gene. This alteration results from a G to A substitution at nucleotide position 1450, causing the alanine (A) at amino acid position 484 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
