  We consider the cross section of the deep inelastic pion electroproduction on
a proton target at threshold for Q^2 in the region 5-10 GeV^2. The
corresponding amplitudes are described in terms of two form factors which we
calculate using light cone sum rules (LCSR) to leading order in QCD and
including higher twist corrections. Our results suggest a considerable change
from a small Q^2 region that can be treated in the soft pion limit using
current algebra. In particular, we obtain a \pi^0 to \pi^+ producton ratio of
order 1/3 and significant nucleon helicity-flip contributions.
