Figure 1From: Complement factor I deficiency: a not so rare immune defect. Characterization of new mutations and the first large gene deletionPedigrees and complement studies. A) Pedigrees of the families with CFI deficiency. Black symbols represent complete deficient of CFI and half-filled symbols indicate partial deficiency. B) Western blot analysis of CFI in serum samples. C) Complement profiles: measurement of C3, C4, CFB, CFH, CFI, C3NeF and CFHA plasma levels. Abbreviations used: NEG, negative. ND, not determined. CFB, Complement Factor B. CFH, Complement Factor H. CFI, Complement Factor I. C3NeF, C3 Nephritic Factor. CFHA, Complement Factor H auto antibodies.Back to article page
