Aiming to relate leptonic CP violating phase [Formula: see text] to the cosmological CP asymmetry, we study the extension of MSSM by two quasi-degenerate (strictly degenerate at tree level) right-handed neutrinos and consider all possible two texture zero [Formula: see text] Yukawa matrices plus one [Formula: see text] dimension five [Formula: see text] operator contributing to the light neutrino mass matrix. We classify all experimentally viable mass matrices, leading to several predictions, and analytically derive predictive relations. We also relate the CP violating [Formula: see text] phase to the CP phase of the thermal leptogenesis.
