1. Previous studies on the pathogenetic mechanisms of hypertension in the Milan hypertensive strain of rat (MHS) showed that a polymorphism within the alpha-adducin gene is responsible for up to 50% of the blood pressure difference between MHS and their MNS normotensive control strain. A case-control study has shown also in humans an association between alpha-adducin locus and hypertension using 4 multiallelic markers surrounding the alpha-adducin locus. 2. With a multiple regression approach we provide an estimate of the contribution of the genotype for each marker to the blood pressure variability in comparison to that provided by sex, body mass index and age. 3. While sex, body mass index and age contributed by about 40-45% to the overall blood pressure variability, the inclusion of the genotype for the marker closer to the alpha-adducin locus provided a further increase of the variability explained of about 5%. 4. The contribution independently provided by the other markers decreased exponentially with the increase of distance from alpha-adducin locus.
