Genes affected

UGGT2 (HGNC:15664): (UDP-glucose glycoprotein glucosyltransferase 2) UDP-glucose:glycoprotein glucosyltransferase (UGT) is a soluble protein of the endoplasmic reticulum (ER) that selectively reglucosylates unfolded glycoproteins, thus providing quality control for protein transport out of the ER.[supplied by OMIM, Oct 2009]

Collection Method: clinical testing

The c.4153C>T (p.R1385W) alteration is located in exon 35 (coding exon 35) of the UGGT2 gene. This alteration results from a C to T substitution at nucleotide position 4153, causing the arginine (R) at amino acid position 1385 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
