Insights
Diagnosing von Willebrand disease (vWD) can be challenging. Integrating genetic testing offers a complementary approach to improve vWD diagnosis and understand its molecular causes.
Area of Science:
- Hematology
- Genetics
- Molecular Pathology
Background:
- Von Willebrand disease (vWD) is the most prevalent inherited bleeding disorder.
- Current diagnostic methods relying on clinical and phenotypic tests can be problematic.
- Advances in VWF gene knowledge and genetic technology enable new diagnostic strategies.
Purpose of the Study:
- To review the genetic basis of various forms of vWD.
- To discuss the integration of genetic testing into vWD diagnostics.
- To explore the role of genetic analysis within inherited bleeding disorder clinics.
Main Methods:
- Literature review of genetic causation of vWD.
- Summary of current knowledge on vWD molecular pathology.
- Description of genetic analysis implementation in clinical settings.
Main Results:
- Significant information on the molecular pathology of vWD has been gathered since the VWF gene cloning.
- Genetic testing is becoming a feasible option for diagnosing vWD in certain cases.
- Genetic analysis has been initiated within a national network of inherited bleeding disorder clinics.
Conclusions:
- Genetic testing presents a feasible complementary diagnostic tool for vWD.
- Further consideration is needed to establish the appropriate role of genetic testing in vWD diagnosis.
- Understanding the genetic causation is crucial for improving vWD management.
Abstract:
Von Willebrand disease (vWD) is the most common inherited bleeding disorder in humans, but its diagnosis, using clinical criteria and phenotypic hemostasis test results, can be problematic. Since the cloning of the von Willebrand factor ( VWF) gene in the mid-1980s, a significant amount of information has been gathered with respect to the molecular pathology responsible for this trait. The extent of this information, along with major advances in genetic technology, has now made the integration of genetic testing for vWD a feasible option in some instances. This review summarizes the current state of knowledge regarding the genetic causation of the various forms of vWD. We also describe how the genetic analysis of vWD has been initiated within the context of a national network of inherited bleeding disorder clinics. In summary, the aim of this review is to prompt a careful consideration of how genetic testing can find an appropriate role as a complementary diagnostic modality for vWD.
