Genetic Association Studies

Stroke is the leading cause of death and disability in Brazil and worldwide, with a significant socioeconomic impact. Despite advances in prevention and treatment, the role of genetic variants in ischemic stroke remains underexplored, especially in genetically diverse populations like Brazil's. International studies such as MEGASTROKE and GIGASTROKE have identified risk loci for stroke, but with low representation of the Latin American population. This study aims to fill that gap by evaluating the prevalence and clinical impact of genetic polymorphisms previously described in Brazilians, thereby laying the groundwork for precision medicine within Brazil's Unified Health System (SUS).
