This set included both lncRNAs that were generally expressed (in all three tissues), including rhabdomyosarcoma 2‐associated transcript (RMST) (Figure 3b), and lncRNAs expressed specifically in the SN, such as solute carrier organic anion transporter family member 4A1 antisense‐1 (SLCO4A1‐AS1) (Figure 3c). Here, SLCO4A1 is linked to rhabdomyosarcoma.
