MNX1 and hematologic disorder: In this study, we aimed to address (i) whether there are consistent patterns of HLXB9 expression in a broad variety of hematological disorders, (ii) if HLXB9 expression is associated with the presence of chromosome 7 abnormalities, (iii) if HLXB9 expression in del(7q) patients varies depending on chromosomal breakpoints, (iv) if HLXB9 expression status is associated with the positioning of the gene in particular nuclear compartments.
