Elevated plasma complement components in facioscapulohumeral dystrophy.

ABSTRACT: Advances in understanding the pathophysiology of facioscapulohumeral dystrophy (FSHD) have led to several therapeutic approaches entering clinical trials and an increased need to develop biomarkers of disease activity and progression. Multiple prior studies have shown early elevation of RNAs encoding components of the complement pathways and relatively widespread activated complement complexes by immunodetection in FSHD muscle. The current study tested plasma from two independent cohorts of FSHD and control subjects and found elevated complement components in both FSHD cohorts. Combining subjects from both cohorts identified complement factors that best distinguished FSHD and controls. Within the FSHD group, a subset of subjects showed elevation in multiple complement components. Together
