We point out that the correlation between the large atmospheric neutrino mixing and the b{yields}s transition, if it exists, comes from the lopsided flavor structure in SO(10) grand unification theory. We suggest testing the correlation by studying the deviation of S{sub {phi}}{sub K{sub S}} and S{sub {eta}{sup '}}{sub K{sub S}} from the standard model predictions along with the constraints from {delta}M{sub B{sub S}} and b{yields}s{gamma} in a realistic SO(10) model with lopsided flavor structure. We find a specific correlation between S{sub {phi}}{sub K{sub S}}S and S{sub {eta}{sup '}}{sub K{sub S}} that is intrinsic to the lopsided structure and discuss how to confirm or rule out this flavor pattern by the more accurate measurements of these CP violation quantities in B decay.
