ANO6 and Quebec platelet disorder: We also assessed other parameters that are known to influence TG, including (a) tissue factor pathway inhibitor (TFPI)17, 18 which influences TG in Quebec platelet disorder (QPD),14 coagulation factor deficiencies,17, 19 and bleeding of unknown cause (BUC)20; (b) platelet factor V (FV), which is stored in α‐granules and is reduced in some PFD14, 21; and (c) platelet ANO6/PPIA transcript ratios as ANO6 mutations cause a severe platelet procoagulant defect known as Scott's syndrome.22, 23
