Hemofilia B leve é uma forma de hemofilia B (veja este termo) caracterizada por uma deficiência leve de fator IX, levando a sangramento anormal como resultado de ferimentos menores ou subsequente a cirurgias ou extrações dentárias. Hemofilia B leve responde por cerca de 30% de todos os casos de hemofilia B. A atividade biológica do fator IX encontra-se entre 5% e 40%. Hemorragias espontâneas não ocorrem. A transmissão é recessiva ligada ao X, e o transtorno é causado por mutações no gene F9 (Xq28), que codifica o fator IX da coagulação. | |||

Mild haemophilia B is a form of haemophilia B characterised by a small deficiency of factor IX leading to abnormal bleeding as a result of minor injuries, or following surgery or tooth extraction. Mild haemophilia B accounts for around 30% of all cases of haemophilia B. The biological activity of factor IX is between 5 and 40%. Spontaneous haemorrhages do not occur. Transmission is X-linked recessive and the disorder is caused by mutations in the F9 gene (Xq28) encoding coagulation factor IX. | |||
