Despite the

better outcome of patients receiving prophylaxis, some will still develop structural joint damage. The new role of angiogenic mediators in the pathogenesis of joint disease remains to be fully elucidated. In future, better understanding of the cause of discrepancies BMS-777607 purchase between patients in outcome of arthropathy and the role of the blockade of chemokine and proangiogenic signalling could hasten the development of effective strategies.

“Summary.  Most bleeding disorders encountered in clinical practice will be diagnosed, at least initially, by phenotypic assays. However, since the characterization of the genes that encode coagulation factors in the 1980s, significant progress has been made in translating this knowledge for diagnostic and therapeutic purposes. For the

haemophilias, in particular, molecular genetic testing to determine carrier status, prenatal diagnosis and prediction of the likelihood of inhibitor development has now become an established component of comprehensive clinical management. For von Willebrand’s disease (VWD), significant recent advances have allowed for Aldol condensation the establishment of genotype–phenotype correlations that have improved our understanding of the disease. The availability of high density single nucleotide polymorphism (SNP) maps will allow investigators to probe the genetic basis of

the general symptoms of bleeding and bruising using a comprehensive genome-wide approach. This article will review the state-of-the-art for molecular diagnostics for both haemophilia and VWD and will end with a discussion of plans for an international genome-wide association study (GWAS) designed to improve our understanding of blood coagulation. Von Willebrand’s disease is the most common inherited bleeding disorder known in humans, with prevalence estimates as high as 1% [2,3]. While an objective personal history of excessive mucocutaneous bleeding can usually be obtained from the patient, the documentation of a family history of the disease may not always be possible, and laboratory tests of haemostasis can be variable in their ability to reveal either a quantitative or qualitative defect of von Willebrand factor (VWF), making the diagnosis of VWD challenging in some situations. With these issues as background, this review will consider the role of molecular genetic analysis as a complementary diagnostic modality, particularly where existing clinical and laboratory approaches to diagnosis have failed to provide a definitive answer. The VWF gene was cloned in 1985 by four groups in the US and Europe [4–7].
