We calculate twist-4 coefficient functions for the deep inelastic structure function F 2 (x, Q 2 ) associated to 4-gluon operator matrix elements for general values of the Bjorken variable x and study the numerical effect on the slope ∂F 2 (x, Q 2 )/∂ log Q 2 . It is shown that these contributions diminish the strongly rising twist-2 terms towards small values of x.
