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]

The c.806T>C (p.I269T) alteration is located in exon 6 (coding exon 6) of the GALNT10 gene. This alteration results from a T to C substitution at nucleotide position 806, causing the isoleucine (I) at amino acid position 269 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
