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]

The c.3725A>G (p.Y1242C) alteration is located in exon 32 (coding exon 32) of the UGGT2 gene. This alteration results from a A to G substitution at nucleotide position 3725, causing the tyrosine (Y) at amino acid position 1242 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
