Type | Description |
1 | Partial quantitative deficit in VWF |
2 | Qualitative deficit in VW |
2A | Interaction failure of VWF with platelets and subendothelium linked to the absence of high MW multimers |
2B | Increased affinity of VWF for platelet GPIb |
2M | Interaction failure of VWF with platelets and subendothelium unrelated to a high PM multimeric abnormalit |
2N | Significant decrease in VWF affinity for FVIII |
3 | Almost total deficit in VWF |
