We point out that the correlation between the large atmospheric neutrino mixing and the b\ensuremath→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_\ensuremathφKS and S_\ensuremathη^\ensuremath'KS from the standard model predictions along with the constraints from \ensuremathΔM_BS and b\ensuremath→s\ensuremathγ in a realistic SO(10) model with lopsided flavor structure. We find a specific correlation between S_\ensuremathφKS and S_\ensuremathη^\ensuremath'KS 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.
