In a patient with total C2 deficiency and repeated respiratory infections a papulovesicular rash showed to be due to leukocytoclastic vasculitis. The patient's brother also had a total deficiency of C2 but no clinical symptoms. HLA-investigation in both him and the proband showed the genotype commonly reported in cases with homozygous C2 deficiency. Their heterozygous mother and sister had slightly decreased C2 levels.
在一名患有完全性C2缺乏症且反复发生呼吸道感染的患者中，丘疹水疱性皮疹被证明是由白细胞破碎性血管炎引起的。该患者的兄弟也存在完全性C2缺乏，但无临床症状。对他和先证者进行的HLA调查显示，其基因型与纯合子C2缺乏症病例中常见的基因型相同。他们的杂合子母亲和姐妹的C2水平略有降低。
