We study the effect of interference between the standard model Higgs boson resonance and the continuum background in the process {gamma}{gamma}{yields}H{yields}bb at a photon collider. Taking into account virtual gluon exchange between the final-state quarks, we calculate the leading corrections to the height of the resonance for the case of a light (m{sub H}<160 GeV) Higgs boson. We find that the interference is destructive and around 0.1%-0.2% of the peak height, depending on the mass of the Higgs and the scattering angle. This suppression is smaller by an order of magnitude than the anticipated experimental accuracy at a photon collider. However, the fractional suppression can be significantly larger if the Higgs coupling to b quarks is increased by physics beyond the standard model.
