Abstract excerpt

The objective of the present study was to investigate the prevalence, clinical characteristics, and HLA association of C2 deficiency in the Brazilian population. The frequency of C2 deficiency profile (C2Q degree profile) was 2.2% among 1503 blood donors and 6.6% among 166 patients with systemic lupus erythematosus (SLE). A higher incidence of clinical manifestations possibly related to immune complex disease was...
