What are the clinical symptoms? Bleeding tendencie ?  You should check
for his vWF (von Willebrand factor). This could be a type of von
Willebrand disease type IIB. This is caused by a mutant von willebrand
factor which spontaneously binds to and aggregates platelets, causing
their  removal from the  circulation. Under conditions were the vWF is
released from the endothelial cells you experience low platelet
counts, under normal conditions normal platelet counts.
