Incidence of hereditary bleeding disorders in Bradford, UK: variation with ethnic group

We have studied the number of patients registered with congenital bleeding disorders at the Haemophilia Centre, Bradford, UK, according to ethnic group. The large Pakistani population in Bradford presents a different spectrum of disorders compared with the indigenous Caucasian population with a significantly higher number of cases of factor VII deficiency and platelet disorders. Other haemophilia centres in the developed world serving large immigrant communities may also manage increased numbers of these rarer disorders with similar implications for resource allocation.
