In Table 1, they selected 12 articles described as “genetic studies of acquired bradykinin-mediated angioedema.” However, the first manuscript from this list is, as its title claims (Hereditary Angioedema with Normal C1 Inhibitor and F12 Mutations in 42 Brazilian Families), a study of HAE patients with normal C1-INH and mutations in F12 gene (Veronez et al., 2018), and not a study of acquired angioedema. This evidence concerns the gene KNG1 and angioedema.
