306 However, recent data indicating that VX-770 potentiates channels bearing multiple disease-causing mutations, spread across CFTR, and that VX-770 potentiates one mutant but not another one in the same domain (for example, VX-770 potentiated TM mutants T338I- and R347H- but not S341P- and E92K-CFTR and potentiated cytoplasmic loop mutants E193K- and K1060T- but not R1066M- and L1065P-CFTR) do not support this conclusion (30, 38).
