SNPs at three loci (TRIB1, LDLR, and CILP2/PBX4) were significantly associated with LDL cholesterol in at least one non-white ethnic group. TRIB1 rs17321515 and LDLR rs1529729 were significantly associated with LDL cholesterol (P = 0.0004 and P = 0.02, respectively) in Mexican Americans. CILP2/PBX4 rs3794991 and LDLR rs6511720 were associated with LDL cholesterol in non-Hispanic blacks (P = 0.04 and P = 8.6 × 10−5, respectively).
