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

Primary immunodeficiency or monogenic inflammatory bowel disease v9.15 CFB Ida Ertmanska changed review comment from: Comment on list classification: There are now 3 unrelated families reported where individuals harbouring biallelic CFB variants presented with immunodeficiency - particularly recurrent meningococcal and pneumococcal infections. Individuals heterozygous for CFB variants present with aHUS / C3G renal disease, rather than PID. Hence, this gene can be promoted to Green on Primary immunodeficiency or monogenic inflammatory bowel disease, with mode of inheritance set to BIALLELIC, autosomal or pseudoautosomal.; to: Comment on list classification: There are now 3 unrelated families reported where individuals harbouring biallelic CFB variants presented with immunodeficiency - particularly recurrent meningococcal and pneumococcal infections.
