Rare Bleeding Disorders in the Netherlands

136 bleeding related OMIM (Online Mendelian Inheritance in Man)-proved genes involved in haemostasis will be selected from Whole Exome Sequencing (WES)

Patients will be approached by their own treating physician. Data will be collected through questionnaires, a clinical interview, a blood and saliva sample obtained from each participant, and thorough review of electronic patient records. All procedures are study related. In case a physician visit with the treating physician is already planned, or in case a venepuncture for regular diagnostics or treatment is already planned, this can be combined with the study procedures to prevent an extra visit.
