To examine whether MM patients display increased PTTG1 expression, we performed in silico analyses in three independent publically available microarray datasets (E-GEOD-6477; E-GEOD-16122; E-MTAB-363) comparing the gene expression profiles of CD138+-isolated plasma cells from newly diagnosed MGUS and MM patients and normal controls. Here, PTTG1 is linked to Miyoshi myopathy.
