  The explanation of a 200 GeV R-parity violating squark to the HERA high-$Q^2$
anomaly would have an important impact on supersymmetry-breaking models. Here
we show that a squark of mass around 200 GeV is disallowed in the minimal
gauge-mediated SUSY-breaking models in the parameter space constrained by the
radiative electroweak-symmetry breaking and the experimental lower limits on
supersymmetric particles, even after including the large R-parity violating
couplings. Supergravity motivated models can, on the other hand, give rise to
these scalar quarks in a wide range of parameter space.
