In addition, Etienne-Grimaldi et al. [21] reported that higher TTP was associated with VEGF-936C>T with the 936T, carried by 23.3% of the patients analyzed, and the VEGF-A -634 G > C polymorphism was associated with a higher toxicity score, with -634C allele carriers likely to develop hypertension and thromboembolic events. This evidence concerns the gene VEGFA and Hypertension.
