Abstract excerpt

OBJECTIVE: To assess the copy number variation of complement C4A and C4B genes in patients with rheumatoid arthritis (RA). METHODS: DNA samples were obtained from 299 patients and controls and analyzed for copy number variation of total complement C4, C4A, and C4B genes. The results were compared by chi-square analysis, and odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated. RESULTS:...
