Modelling pathogenesis and treatment of familial dysautonomia using patient-specific iPSCs

The derivation and differentiation of disease-specific human induced pluripotent stem cells (iPSCs) offers a new strategy for modelling disease. Familial dysautonomia (FD) is a rare but fatal peripheral neuropathy caused by a mutation in the IKBKAP gene. Here, patient-specific FD-iPSCs are derived and differentiated into cells of all three germ layers, including peripheral neurons; the cells are then analysed for mechanism of disease specificity and response to candidate drugs.
