ProteinExpression: Flow cytometry was performed and expression is stated as pathogenic in Table 1

PlateletAggregation: Platelet aggregation was performed and is stated as pathogenic in Table 1; however, no specific agonists mentioned

CasePreviousTesting: All exons of ITGA2B and ITGB3 genes as well as surrounding intron regions were amplified by PCR using intronic primers as pre-viously described (12). The purified DNA fragments were then di-rectly sequenced.
