In the last sentence of the first full paragraph on page 1895, a relevant reference was not cited. The sentence should read, “Although prior work using overexpression of MYH9-RD mutants in megakaryoblast cell lines has reported defective migration properties in an SDF-1 gradient,74 we not only demonstrate in situ MK migration anomalies in BM but also show that different point mutations associated with the disease inhibit chemotaxis by disparate mechanisms (supplemental Table 1).”
In “References” on page 1898, reference 74 should be added as follows:
74. Pecci A, Bozzi V, Panza E, et al. Mutations responsible for MYH9-related thrombocytopenia impair SDF-1-driven migration of megakaryoblastic cells. Thromb Haemost. 2011;106(4):693-704.
