von Willebrand disease (VWD) is the most common inherited bleeding disorder in humans. Caused by mutations in the von Willebrand factor (VWF) gene, these defects result in qualitatively abnormal variants of VWF (classified as type 2 VWD) or a decrease in VWF levels (types 1 and 3 VWD). Type 3 VWD is the most severe type and usually presented with undetectable VWF level. In this report, we describe a type 3 VWD patient. Molecular analysis of the whole VWF gene reveals two novel mutations, c.2480G>A (p.C827Y) in exon 19 and c.3897delT in exon 28.
血管性血友病（VWD）是人类最常见的遗传性出血性疾病。由血管性血友病因子（VWF）基因突变引起，这些缺陷导致VWF出现质量异常的变体（归类为2型VWD）或VWF水平降低（1型和3型VWD）。3型VWD是最严重的类型，通常表现为VWF水平检测不到。在本报告中，我们描述了一名3型VWD患者。对整个VWF基因的分子分析揭示了两个新的突变，外显子19中的c.2480G>A（p.C827Y）和外显子28中的c.3897delT。
