Article Synopsis
  • - Chronic Chagas Cardiomyopathy (CCC) develops years after parasitic infection and is a major cause of heart failure in Latin America, yet only a small percentage of infected individuals develop the disease.
  • - A genome-wide association study (GWAS) identified a new susceptibility locus (rs34238187) linked to CCC in Brazilian populations, with significant associations to various immune-related traits.
  • - The findings suggest that this genetic locus plays a role in modifying the immune response to the T. cruzi parasite, highlighting the need for further research into its functional character and impact on CCC risk.

Background: Care to patients with Chagas disease (CD) is still a challenge for health systems in endemic and non-endemic countries.
