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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 12, 2023The c.26G>T (p.G9V) alteration is located in exon 1 (coding exon 1) of the UGGT1 gene. This alteration results from a G to T substitution at nucleotide position 26, causing the glycine (G) at amino acid position 9 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
