Inheritance Patterns of von Willebrand Disease
Von Willebrand disease is characterized by various inheritance patterns. The most common types, type 1 and type 2, are inherited in an autosomal dominant pattern. This means that the disease can be caused by just one copy of an abnormal gene in each cell. In some rare cases, individuals may inherit type 2 or type 1 in an autosomal recessive pattern, which means that both copies of the gene are abnormal. This typically occurs when both parents carry the condition but exhibit either mild symptoms or no symptoms at all, often remaining unaware of their own condition. On the other hand, type 3 von Willebrand disease is inherited in an autosomal recessive pattern.
Complications of Von Willebrand Disease
Von Willebrand disease can give rise to various complications. Women, especially during menstruation, are at risk of developing iron deficiency anemia if they experience prolonged bleeding. In some cases, abnormal bleeding in the joints can lead to swelling and pain. Although rare, there are instances where individuals may experience severe bleeding that necessitates immediate medical intervention. If left untreated, this excessive bleeding can result in serious consequences like heart attacks, strokes, or even death.
