In addition, associations have been recorded between SNPs in ARL6IP6 and SBP or DBP in African and Asian individuals [34, 35]; MYRF and DBP in Europeans [30]; KCNQ1 and DBP, SBP or early onset hypertension in African, European or mixed populations [30, 36–38]; NOS1AP, PLEKHH2 and POC1B and SBP or DBP in Europeans [30]; SCARB1 and SBP in Europeans [30]; and STK33 and TAX1BP1 and hypertension in Europeans [39].
