Other Factor Deficiencies

In the US, a rare disease or disorder is defined as one that affects fewer than 200,000 people, making hemophilia A and B, and still less prevalent factor deficiencies such as I, II, V, VII, X, XI, XII and XIII, rare disorders. These very rare factor deficiencies, from factor XIII deficiency, the rarest, occurring in an estimated 1 out of 5 million people, to factor XI deficiency, occurring in about 1 out of 100,000, were all discovered and identified in the 20th century. The majority of these conditions were only identified within the last 60-70 years. Here you will find information on how factor deficiencies I, II, V, VII, X, XI, XII and XIII are inherited identified and managed.
