  We present a formalism and explicit results for two-loop flavor singlet
evolution kernels of skewed parton distributions in the minimal subtraction
scheme. This approach avoids explicit multiloop calculations in QCD and is
based on the known pattern of conformal symmetry breaking in this scheme as
well as constraints arising from the graded algebra of the $\cN = 1$ super
Yang-Mills theory. The conformal symmetry breaking part of the kernels is
deduced from commutator relations between scale and special conformal anomalies
while the symmetric piece is recovered from the next-to-leading order splitting
functions and $\cN = 1$ supersymmetry relations.
