Genes affected

GALNT10 (HGNC:19873): (polypeptide N-acetylgalactosaminyltransferase 10) This gene encodes a member of the GalNAc polypeptide N-acetylgalactosaminyltransferases. These enzymes catalyze the first step in the synthesis of mucin-type oligosaccharides. These proteins transfer GalNAc from UDP-GalNAc to either serine or threonine residues of polypeptide acceptors. The protein encoded by this locus may have increased catalytic activity toward glycosylated peptides compared to activity toward non-glycosylated peptides.[provided by RefSeq, Apr 2010]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.823C>T (p.R275W) alteration is located in exon 6 (coding exon 6) of the GALNT10 gene. This alteration results from a C to T substitution at nucleotide position 823, causing the arginine (R) at amino acid position 275 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
