Genes affected

MASTL (HGNC:19042): (microtubule associated serine/threonine kinase like) This gene encodes a microtubule-associated serine/threonine kinase. Mutations at this locus have been associated with autosomal dominant thrombocytopenia, also known as thrombocytopenia-2. Alternatively spliced transcript variants have been described for this locus.
