But using the genome scan, the only study that reported regions containing five genomic markers on various chromosomes (D3S2387, D11S2019, D15S657, D16S3396 and D17S1303) for systolic and diastolic blood pressure in their primary analysis and eight regions in a secondary analysis (D4S3248, D72195, D101423, D20S470, D20S482, D21S2052, PAH and AGT) highlighted chromosomes 11 and 17 as putative regions for harbouring hypertension genes [29]. This evidence concerns the gene PAH and hypertensive disorder.
