We compile a list of all SNVs previously reported to be associated with BP at the time of analysis (Supplementary Table 13). This list includes all published SNVs which have been identified and validated from previous GWAS, CardioMetabochip and exome chip projects7–11. We augment this list to include all 34,459 SNVs in Linkage Disequilibrium (LD) with these previously reported SNVs, according to a threshold of r2 ≥ 0.2. Results for all these variants are extracted for each of the three BP traits, to check previously reported BP associations in the UKB data, according to whether the sentinel SNV or a variant at the locus in LD (r2 ≥ 0.2) with it showed evidence of support (P < 0.01) for association with at least one of the three BP traits.
