Input: We performed genome-wide analyses to identify genomic loci that interact with sodium to influence blood pressure (BP) using single-marker-based (1 and 2 df joint tests) and gene-based tests among 1876 Chinese participants of the Genetic Epidemiology Network of Salt-Sensitivity (GenSalt) study. Among GenSalt participants, the average of 3 urine samples was used to estimate sodium excretion. Nine BP measurements were taken using a random zero sphygmomanometer. A total of 2.05 million single-nucleotide polymorphisms were imputed using Affymetrix 6.0 genotype data and the Chinese Han of Beijing and Japanese of Tokyo HapMap reference panel. Promising findings (P<1.0010(-4)) from GenSalt were evaluated for replication among 775 Chinese participants of the Multi-Ethnic Study of Atherosclerosis (MESA). Single-nucleotide polymorphism and gene-based results were meta-analyzed across the GenSalt and MESA studies to determine genome-wide significance. The 1 df tests identified interactions for UST rs13211840 on diastolic BP (P=3.1310(-9)). The 2 df tests additionally identified associations for CLGN rs2567241 (P=3.9010(-12)) and LOC105369882 rs11104632 (P=4.5110(-8)) with systolic BP. The CLGN variant rs2567241 was also associated with diastolic BP (P=3.1110(-22)) and mean arterial pressure (P=2.8610(-15)). Genome-wide gene-based analysis identified MKNK1 (P=6.7010(-7)), C2orf80 (P<1.0010(-12)), EPHA6 (P=2.8810(-7)), SCOC-AS1 (P=4.3510(-14)), SCOC (P=6.4610(-11)), CLGN (P=3.6810(-13)), MGAT4D (P=4.7310(-11)), ARHGAP42 (P1.0010(-12)), CASP4 (P=1.3110(-8)), and LINC01478 (P=6.7510(-10)) that were associated with at least 1 BP phenotype. In summary, we identified 8 novel and 1 previously reported BP loci through the examination of single-nucleotide polymorphism and gene-based interactions with sodium.
