Genes affected

DSTYK (HGNC:29043): (dual serine/threonine and tyrosine protein kinase) This gene encodes a dual serine/threonine and tyrosine protein kinase which is expressed in multiple tissues. It is thought to function as a regulator of cell death. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2008]
