SERPING1 and hereditary angioedema: Participants with HAE-nl-C1INH reported numerically more peripheral, abdominal, and genital area swells than those with HAE Type 1/2 and were more likely to report orofacial-laryngeal (i.e., face, tongue, and throat) swells (OR, 2.3; 95% CI, 1.1–4.7) compared with participants with HAE Type 1/2 (31% vs. 16%, respectively) despite similar participant counts.
