| Primary immunodeficiency or monogenic inflammatory bowel disease v9.18 | CFB |
Ida Ertmanska changed review comment from: PMID: 41663882 Bougeard et al., 2026 Report of a 14yo French girl with Neisseria meningitidis serogroup Y meningitis complicated by bacteremia and cerebral venous sinus thrombosis. She was found to be comp het for CFB: p.Gly396Arg and p.Gln713Arg. PMID: 33165708 Gauthier et al., 2021 8yo male, Caucasian, with repeated pneumococcal infections: pneumococcal bacteriemia at 4 months, pneumococcal meningitis and bacteriemia at 11 months, empyema caused by S. pneumoniae at 8 years: pneumonia with septic shock and acute respiratory distress syndrome (intubated for 9 days + mechanical ventilation + 7 days of extracorporeal membrane oxygenation). Compound heterozygous for CFB variants c.1938dup, p.(Ile647Hisfs*6) and c.1186G>A, p.(Gly396Arg). PMID: 24152280 Slade et al., 2018 32yo female, recurrent episodes of pneumococcal and meningococcal infections starting at age 2 yrs. She was compound heterozygous for CFB: c.766C>T, p.Gln256* (nonsense), c.1895_1898del, p.Phe632Cysfs*8 (frameshift). Factor B levels were undetectable in the patient. PMCID: PMC3334074 Dehoorne et al., 2008 Report of a 16-y-old Caucasian girl, who presented with recurrent episodes of aseptic meningitis. She presented with a 2-week history of headache, vomiting, neck stiffness, facial palsy, equilibrium problems, diplopia, and low grade temperature. 4 months prior to admission she presented with a leucocytoclastic vasculitis. Biochemical testing showed very low levels of factor B (1mg/dl), but normal factors I and H. No genetic testing described. CFB is associated with AR Complement factor B deficiency, MIM:615561 and AD {Hemolytic uremic syndrome, atypical, susceptibility to, 4}, MIM:612924 in OMIM (accessed 22nd Jun 2026). The association between CFB and AD C3 glomerulonephritis was classified as Limited (Nov 2024), and CFB-related AD atypical hemolytic-uremic syndrome with B factor anomaly was classified as Moderate (July 2023) by the ClinGen Complement-Mediated Kidney Diseases GCEP.; to: PMID: 41663882 Bougeard et al., 2026 Report of a 14yo French girl with Neisseria meningitiis serogroup Y complicated by bacteremia and cerebral venous sinus thrombosis.
