Genes affected

UGGT1 (HGNC:15663): (UDP-glucose glycoprotein glucosyltransferase 1) 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.715G>A (p.V239I) alteration is located in exon 7 (coding exon 7) of the UGGT1 gene. This alteration results from a G to A substitution at nucleotide position 715, causing the valine (V) at amino acid position 239 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
