The HLA profiles of mixed connective tissue disease differ distinctly from the profiles of clinically related connective tissue diseases

摘要

Objective. The Norwegian nationwide MCTD cohort was established to obtain unbiased data on key disease issues, and thereby reappraise the concept of MCTD. In the current study, the aims were to obtain detailed HLA profile data on the large Norwegian MCTD cohort and compare these with the HLA profiles of ethnically matched healthy controls and related CTD controls.
