  The observed neutrino flavor transitions are currently explained by the three
flavor neutrino oscillation phenomenon, considered to be the leading order
mechanism behind the flavor transitions. Currently existing data from LSND,
MiniBooNE and reactor experiments demonstrate anomalies that could potentially
be indications of non-standard neutrino phenomena. MINOS can probe transitions
from muon neutrinos to electron neutrinos and search for anomalous behavior
that cannot be explained by standard model neutrino oscillations. Here we
present the search for second order effects in the flavor transitions by
analyzing the MINOS $\nu_\mu \to \nu_e$ channel.
