Rare-variant collapsing analyses of arterial hypertension in the UK biobank

The importance of rare variation in hypertension is unclear. The present study uses UK biobank to analyse the association of rare coding variants to hypertension using gene collapsing data (https:// azphewas.com/ and https://app.genebass.org/). Arterial hypertension is an important contributor to the global burden of disease [1]. It is a multifactorial disease, with environmental, genetical, and social determinants [1]. Genetic loci associated with blood pressure comprises >30 genes, with rare variants resulting in monogenic forms of hypertension or hypotension [2]. Totally more than 1477 common single-nucleotide polymorphisms (SNPs) are associated with the blood pressure phenotype [2]. Still, SNPs identi fi ed in genome wide association studies (GWAS) of hypertension only explains around 27% of the 30 – 50% estimated heritability of blood pressure [2]. The availability of whole-genome sequencing (WES) data in large studies have enabled investigation of the contribution of rare variants to blood pressure and hypertension [3]. We have used two published UK biobank portals (https://azphewas.com/ and https://app.genebass.org/) [4, 5] to access gene collapsing analysis of rare variation for hypertension (Table 1). We did not obtain ethical approval because we used two public UK biobank portals (https:// azphewas.com/ and https://app.genebass.org/) [4, 5]. The study by Wang et al. reported the relationships between rare protein-coding variants and 17,361 binary phenotypes using WES data from 269,171 UK Biobank exomes
