Among the cases of mild type 1 VWD, 20 patients had normal platelet VWF levels (96.4+/-4.0 U/dL [normal range 70–140 U/dL]) and 44 had a reduced platelet content (47.2+/-2.5 U/dL) (Table 1), but the multimer organization revealed no significant abnormalities in either instance. The gene discussed is VWF; the disease is von Willebrand disease 1.
