We discuss the possibility of measuring generalized parton distributions in exclusive electro‐production of mesons off the nucleon and estimate the uncertainty from perturbatively induced higher‐twist corrections. We find that, while the magnitude of the cross section changes significantly taking into account twist‐four contributions modeled via renormalons, the transverse spin asymmetry is weakly sensitive to them and displays the precocious scaling.
