BTBD7-SLC2A5 may be involved in unregulated cell adhesion, motility and epithelial morphogenesis due to loss of exons 10 and 11 of BTBD7, or be involved in shifting of energy metabolism to enhance tumor growth due to containing entire transmembrane domain and fructose transport domain of SLC2A5. The gene discussed is SLC2A5; the disease is neoplasm.
