An error occurred in the BRIEF REPORT "Familial Angioedema Associated With C1 Esterase-Inhibitor Deficiency: A New Genetic Variant of Hereditary Angioedema?" published in the March 26 issue of The Journal (1982;247:1734-1736). The legends for the figures on pages 1735 and 1736 should have read as follows: Fig 1.—C1 esterase inhibitor (C1 INH), C4, and C2 values during danazol treatment. Sensitivity of assay is 4 mg/dL for both C1 INH and C4. Normal range for C2 is 1.6 to 3.6 mg/dL. Normal range for C1 INH is 14 to 30 mg/dL; C4, 15 to 35 mg/dL. Fig 2.—HLA haplotypes. Fig 3.—C1 esterase inhibitor (C1 INH) and C4 values.
