Summary

This study is for adults aged 18 to 55 who were diagnosed with type 1 diabetes within the last 6 months. Researchers want to see how many of them carry a specific gene called HLA-DRB1*04:01. Participants will provide a blood sample or cheek swab for genetic testing. The goal is to understand how common this gene is in different ethnic and racial groups, which could help guide future treatments.
