In deep-inelastic scattering experiments, there is a general connection between subtractions in dispersion relations, violations of sum-rules and δ-functions in parton distribution functions. It is explained why one might expect a small violation in sum rules for the twist-3 distribution functions gT(x) and hL(x) when the sum-rules are applied to x≠ 0 data only. The non-perturbative predictions are studied in the context of a one-loop model.
