To identify and characterize the causal mutations, we screened 10 Italian patients with VWD3 by several techniques including Multiplex Ligation\u2010dependent Probe Amplification to identify large insertions and deletions, High Resolution Melting and PCR coupled with Sanger sequencing. Fourteen different mutations scattered throughout the VWF gene were identified, 10 of which were novel. As expected, most of these mutations caused null alleles: five were deletions (del exons 1\u20133, del exon 17, c.2157delA, c.2269delCT, and c.3940delG), three nonsense (p.Q1526X, p.E1549X, and p.C2448X) and three potential splice\u2010site mutations (c.658\u20102A&gt;G, c.7729+7C&gt;T, and c.8155+1G&gt;T). Three candidate missense mutations (p.C2184S, p.C2212R, and p.C2325S) were also identified. Missense mutations and the putative splice\u2010site defects were confirmed to be disease related by <jats:italic>in vitro<\/jats:italic> expression studies and mRNA analysis. None of these patients have developed alloantibodies against VWF. This study extends our previous finding that most of the mutations that we identified in VWD3 patients arise independently and are scattered throughout the entire VWF gene. Am. J.
