Název v původním jazyce

Five novel mutations in the C1 inhibitor gene (C1NH) leading to a premature stop codon in patients with type I hereditary angioedema.

Popis výsledku v původním jazyce

Hereditary angioedema (HAE) is a disorder characterised by recurrent attacks of localized subcutaneous or submucosal edema. It is inherited in an autosomal dominant fashion and caused by a deficiency of C1 inhibitor (C1 inh, or C1NH). Most patients withHAE have an absolute deficiency of C1 inh (type I HAE) while the rest (15% of kindreds) synthetize a dysfunctional C1 inh protein (type II HAE). In this report a novel use of denaturing gradient gel electrophoresis (DGGE) followed by direct sequencing ofthe C1 inhibitor gene is presented. Five novel mutations, one nonsense (p.S48X) and four small deletions resulting in frameshifts (g.2264-2265delAG, g.2304delC, g.8493-8494delCC and g.16676-16677delTG) have been identified in the C1 inhibitor gene in five families with type I HAE. All of these mutations lead to premature termination of translation and thus can be considered causative of the C1 inh deficiency. Moreover, two previously described mutations in the reactive center of C1 inh,
