Understanding genetic causes of autoimmune diseases in diverse populations

This research study is investigating the genetic roots of autoimmune diseases—conditions where the body's immune system attacks itself—with a focus on understanding why diseases like lupus occur earlier and more severely in certain populations. Researchers will collect blood samples and genetic information from people diagnosed with autoimmune diseases and their family members, primarily in Peru and Latin America. The goal is to identify genetic differences that explain why some communities are at higher risk and to develop better, more personalized treatments.

Most genetic studies of autoimmune diseases have focused on people of European descent, leaving a major gap in understanding how these diseases affect indigenous and other populations. This research exists to fill that gap and help explain why autoimmune diseases often strike earlier and harder in non-European communities—knowledge that could lead to better diagnosis and treatment for everyone.
