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]

Collection Method:clinical testing

The c.215G>A (p.S72N) alteration is located in exon 3 (coding exon 3) of the UGGT1 gene. This alteration results from a G to A substitution at nucleotide position 215, causing the serine (S) at amino acid position 72 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
