Additionally, to explore the relationship between HSP90AB1 CNVs and clinical manifestations in SLE patients, we further compared the associations of HSP90AB1 CNVs and nephritis, arthritis, photosensitivity, serositis, skin lesions, alopecia, oral ulcers and fever, but there were no significant differences (Table S2). The gene discussed is HSP90AB1; the disease is Arthritis.
