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.748A>G (p.I250V) alteration is located in exon 7 (coding exon 7) of the UGGT1 gene. This alteration results from a A to G substitution at nucleotide position 748, causing the isoleucine (I) at amino acid position 250 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
