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.523C>T (p.P175S) alteration is located in exon 6 (coding exon 6) of the UGGT1 gene. This alteration results from a C to T substitution at nucleotide position 523, causing the proline (P) at amino acid position 175 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
