  Flavour models may display a relation between the CP-violating asymmetry for
leptogenesis and low-energy parameters. If the flavour symmetry produces an
exact mass independent lepton mixing scheme at leading order (with type I
see-saw) the CP-violating asymmetry would vanish in the absence of corrections.
We present a model displaying the link between deviations from the mixing
scheme and leptogenesis.
