E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Haemophilia B is a recessive X-linked congenital bleeding disorder, caused by mutations in the coagulation factor nine (FIX) gene, located in the distal part on the long arm of the X-chromosome. Haemophilia B is caused by any of a variety of genetic anomalies distributed throughout the gene, with almost every family. |
L’emofilia B è una malattia emorragica congenita recessiva legata al cromosoma X, causata da mutazioni nel gene del fattore di coagulazione IX (FIX), situato nella parte distale sul braccio lungo del cromosoma X. L’emofilia B è causata da una serie di anomalie genetiche distribuite per tutto il gene, di cui quasi ogni famiglia manifesta la propria configurazione unica. |
