  We propose a new $\mathrm{SU}(3)_C \otimes \mathrm{SU}(2)_{L}\otimes
\mathrm{U}(1)_{Y}\otimes \mathrm{U}(1)_{X}$ gauge model which is non universal
respect to the three fermion families of the Standard Model. We introduce
additional one top-like quark, two bottom-like quarks and three right handed
neutrinos in order to have an anomaly free theory. We also consider additional
three right handed neutrinos which are singlets respect to the gauge symmetry
of the model to implement see saw mechanism and give masses to the light
neutrinos according to the neutrino oscillation phenomenology. In the context
of this horizontal gauge symmetry we find mass ansatz for leptons and quarks.
In particular, from the analysis of solar, atmospheric, reactor and accelerator
neutrino oscillation experiments, we get the allow region for the Yukawa
couplings for the charge and neutral lepton sectors according with the mass
squared differences and mixing angles for the two neutrino hierarchy schemes,
normal and inverted.
