Differentially expressed genes from our dataset were subsequently analyzed in 2 published datasets [23, 24] (GSE6691, GSE6477) to compare expression in CD138 selected cells from MM patients with CD138 selected cells from NBM; 47 genes showing a ≥ 2-fold difference and a p-value of ≤ 0.05 were selected for qPCR validation. The gene discussed is SDC1; the disease is Miyoshi myopathy.
