Genes affected

GALNT17 (HGNC:16347): (polypeptide N-acetylgalactosaminyltransferase 17) This gene encodes an N-acetylgalactosaminyltransferase. This gene is located centromeric to the common deleted region in Williams-Beuren syndrome (WBS), a multisystem developmental disorder caused by the deletion of contiguous genes at 7q11.23. This protein may play a role in membrane trafficking. [provided by RefSeq, Jan 2013]
