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]

Ambry Genetics

Jan 06, 2023

The c.1190G>C (p.G397A) alteration is located in exon 12 (coding exon 12) of the UGGT1 gene. This alteration results from a G to C substitution at nucleotide position 1190, causing the glycine (G) at amino acid position 397 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
