The detection of a non-Gaussian component in the primordial matter density perturbations could represent a powerful tool to discriminate between inflationary models. While the Planck mission might provide evidence for a large primordial non-Gaussianity, the measurement of such signal in the Large-Scale Structure would constitute a fundamental confirmation. I will review the relevant observables in the large-scale galaxy distribution sensitive to non-Gaussian initial conditions with particular attention to the most recent developments and I will discuss future perspectives.
