►大约一半的AC-26核型患者具有系统性自身免疫性风湿疾病的临床特征 (干燥综合征、系统性红斑狼疮、未分化的结缔组织病、局限型系统性硬化症、或类风湿性关节炎)；AC-26核型在器官特异性自身免疫性疾病的患者中也被观测到，在非自身免疫性疾病中更少见，尤其是在抗体滴度较低时 (109, 111–114)
►在常规血清学诊断中非常少见 (109)
►所识别的抗原包括NuMA、亲中心体蛋白 (centrophilin)、SP-H抗原和NMP-22；这些自体抗体的特异性免疫检测试剂目前尚未商品化 (115)
► Approximately one-half of the patients with the AC-26 pattern have clinical features of a SARD (SjS, SLE, UCTD, limited SSc, or RA); the AC-26 pattern is also observed in patients with organ-specific autoimmune diseases and less frequently in non-autoimmune conditions, especially when in low titer (109, 111–114)
► Found very infrequently in a routine serology diagnostic setting (109)
► Antigens recognized include NuMA, centrophilin, SP-H antigen and NMP-22; specific immunoassays for these autoantibodies are currently not commercially available (115)
