Hypertension is an important risk factor for death from stroke, heart disease, and kidney failure and affects about one-quarter of all adults word wide. In August 10
Wilsonet al. began to unravel the genetics of this new pathway by identifying two types of families affected with hypertension. Each carried a specific genetic mutation, one on chromosome 12, and the other on chromosome 17. The breakthrough came when it was noticed that a genetic marker present in the normal chromosome 12 was absent in the mutated disease gene. Genomic analysis showed that the deletion was within a gene called WNK1, ...
