Additional Information:

Clinical Description OMIM Fremeaux-Bacchi et al. (2004) reported 3 unrelated patients with aHUS. The first patient was a 32-year-old woman who developed aHUS after pregnancy. Renal biopsy showed thrombotic microangiopathy. She had decreased serum factor I, factor B (CFB; 138470), and ...
Molecular genetics OMIM In 3 unrelated patients with aHUS, Fremeaux-Bacchi et al. (2004) identified heterozygous mutations in the complement factor I gene (217030.0004-217030.0006). In 2 families, a clinically unaffected parent also carried the mutation, suggesting incomplete penetrance and that heterozygous mutations ...
