Glucocorticoid receptor gene polymorphisms in hereditary angioedema with C1-inhibitor deficiency

摘要

BackgroundHereditary angioedema caused by C1-inhibitor deficiency (C1-INH-HAE) is a rare, autosomal dominant disorder. C1-INH-HAE is characterized by edema–formation, which may occur in response to stress. The individual’s response to stress stimuli is partly genetically determined. Activation of the hypothalamic–pituitary–adrenal axis results in the release of cortisol. In turn, the secreted gluco- and mineralocorticoids affect the metabolism, as well as the cardiovascular and immune systems. We hypothesized that changes in serum cortisol level and polymorphisms of the glucocorticoid receptor (GR) modify the individual sensitivity to stressor stimuli of C1-INH-HAE patients.
