- Von Willebrand disease (vWD) (/ˌfʌnˈvɪlɨbrɑːnt/) is the most common hereditary coagulation abnormality described in humans, although it can also be acquired as a result of other medical conditions.he von Willebrand factor is qualitatively normal and genetic testing of the von Willebrand gene and vWF protein reveals no mutational alteration. The defect lies in the qualitatively altered glycoprotein Ib (GPIb) receptor on the platelet membrane which increases its affinity to bind to the von Willebrand factor.

- Dogs with this type produce virtually no vWF, and will usually have several bleeding episodes before reaching adulthood. VetNostic Laboratories’ genetic tests for von Willebrand Disease can reliably identify dogs that are either clear, or possess one or two copies of the vWD causing gene.

Von Willebrand disease There are three forms of vWD: hereditary, acquired, and pseudo or platelet type. There are three types of hereditary vWD: vWD type 1, vWD type 2, and vWD type 3. Within the three inherited types of vWD there are various subtypes. Platelet type vWD is also an inherited condition. vWD type 1 is the most common type of the disorder and those that have it are typically asymptomatic or may experience mild symptoms such as nosebleeds although there may be severe symptoms in some cases.

Von Willebrand disease There are various factors that affect the presentation and severity of symptoms of vWD such as blood type. vWD is named after Erik Adolf von Willebrand, a Finnish physician who first described the disease in 1926.ype 3 is the most severe form of von Willebrand disease (homozygous for the defective gene) and is characterized by complete absence of production of vWF. The von Willebrand factor is undetectable in the vWF antigen assay.

Bleeding Disorders Many more people are affected by von Willebrand disease, the most common inherited bleeding disorder in America caused by clotting proteins. Von Willebrand disease can affect both males and females. Platelet disorders are the most common cause of bleeding disorder and are usually acquired rather than inherited.ndividuals and pregnant women with a family history of bleeding disorders should talk to their doctors about detection and treatment. Symptoms of bleeding disorders may include: 1  Easy bruising. 2  Bleeding gums. 3  Heavy bleeding from small cuts or dental work. 4  Unexplained nosebleeds.

Diagnosis If you have von Willebrand disease, your doctor may recommend that family members undergo the same or similar tests to determine if this condition runs in your family. Treatment. Even though von Willebrand disease is a lifelong condition with no cure, treatment can help prevent or stop bleeding episodes. Your treatment depends on: The type and severity of your condition

- Jennifer S Tirnauer, MD. Von Willebrand disease (VWD) is the most common of the inherited bleeding disorders, with a prevalence of approximately 1 percent when random laboratory screening is performed. Although VWD is common, only a fraction of patients come to medical attention because of bleeding symptoms and are diagnosed as having VWD.

Overview of Coagulation Disorders The most common hereditary disorder of hemostasis is von Willebrand disease (see Von Willebrand Disease) The most common hereditary coagulation disorders are the hemophilias. NOTE: This is the Professional Version. NOTE: This is the Professional Version. Abnormal bleeding can result from disorders of the coagulation system (see Overview of Hemostasis), of platelets, or of blood vessels. Disorders of coagulation can be acquired or hereditary.

Von Willebrand disease Von Willebrand disease is caused by a deficiency of von Willebrand factor. Von Willebrand factor helps blood platelets clump together and stick to the blood vessel wall, which is necessary for normal blood clotting.

- Autosomal recessive congenital methemoglobinemia is an inherited condition that mainly affects the function of red blood cells. Specifically, it alters a molecule within these cells called hemoglobin.Hemoglobin carries oxygen to cells and tissues throughout the body.utations that cause autosomal recessive congenital methemoglobinemia type II usually result in a complete loss of enzyme activity. Cells cannot compensate for a complete loss of this enzyme, which results in a 10 to 70 percent increase in methemoglobin within red blood cells.

Von Willebrand Disease: Types, Causes, and Symptoms A genetic mutation causes von Willebrand disease. The type of von Willebrand disease that you have depends on whether one or both of your parents have passed a mutated gene on to you. For example, you can only develop type 3 Von Willebrand if you’ve inherited a mutated gene from both of your parents.

5 Signs and Symptoms of von Willebrand Disease The signs and symptoms of von Willebrand disease vary depending on the type and severity of the disease. VWD is almost always hereditary. If someone in your family has VWD or you have any of the following symptoms, talk to your health care professional: 1  frequent or hard-to-stop nosebleeds that happen spontaneously, occur often (five times or more a year) or last longer than 10 minutes.

Hereditary hemorrhagic telangiectasia Hereditary hemorrhagic telangiectasia. Hereditary hemorrhagic telangiectasia (HHT), also known as Osler–Weber–Rendu disease and Osler–Weber–Rendu syndrome, is a rare autosomal dominant genetic disorder that leads to abnormal blood vessel formation in the skin, mucous membranes, and often in organs such as the lungs, liver, and brain.

- Von Willebrand disease (VWD) is almost always inherited. Inherited means that the disorder is passed from parents to children though genes. You can inherit type 1 or type 2 VWD if only one of your parents passes the gene on to you. You usually inherit type 3 VWD only if both of your parents pass the gene on to you.

von Willebrand disease von Willebrand disease. Description. von Willebrand disease (VWD) is a disorder that is caused by a problem with one of the proteins in the blood (von Willebrand factor or vWF). People with VWD either don’t have enough vWF or what they have doesn’t work properly. vWF plays 2 important roles in blood clotting.
