Status of determination of the lepton mixing is summarized. There are some evidences that mixing matrices of leptons and quarks are related as U(PMNS) = V(CKM) x U(M), where U(M) is a matrix of special form with maximal rotation(s). If not accidental, the relation could imply the Grand Unification, see-saw mechanism of neutrino mass generation and some new physics with flavor symmetries. Realization of such a possibility includes SO(10) GUT , neutrino portal interactions and the Planck scale hidden sector composed of fermions and scalars (flavons).
