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]

The c.1861G>A (p.D621N) alteration is located in exon 17 (coding exon 17) of the EDEM3 gene. This alteration results from a G to A substitution at nucleotide position 1861, causing the aspartic acid (D) at amino acid position 621 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
