Abstract
dc.description.abstract
The GTPase Rac1 has been implicated in hypertension as a modulator
of mineralocorticoid receptor activity. Our aim is to investigate the
frequency of polymorphisms rs10951982 (intron 1, G>A) and rs836478
(intron 3, T>C) in the RAC1 gene and perform association studies with
clinical and biochemical parameters in a Chilean pediatric cohort.

Figure 2. Genotype distribution and biochemical associations of the polymorphisms rs10951982 and rs836478 of the RAC1 gene in normotensive subjects
with hypertensive parents (NH) and normotensive subjects with normotensive parents (NN) (P <0.05). (a) Results obtained for single nucleotide polymorphism
(SNP) rs10951982 located in intron 1. The group of children with GA/AA genotype had lower diastolic blood pressure (DBP) index compared with
subjects with GG genotype. (b, c, and d) Results obtained for SNP rs836478 located in intron 3, using the Kruskal–Wallis and Dunn’s test (P < 0.05). (b) The
group of NN children with TT genotype had higher plasminogen activator inhibitor-1 levels compared with subjects with TC/CC genotype. The group of NH
children with TT genotype had (c) higher metalloproteinase-9 levels and (d) lower interleukin 6 (IL-6) levels compared with subjects with TC/CC genotype.
