Polimorfismo Val247Leu do gene β2-glicoproteína 1 pode justificar a gênese de anticorpos antiβ2GP1 e síndrome do anticorpo antifosfolípide na hanseníase multibacilar

Abstract: FUNDAMENTOS - Anticorpos antifosfolípides (AAF), como antiβ2GP1 (β2-glicoproteína 1), são descritos na hanseníase multibacilar (MB) sem, contudo, caracterizar a síndrome do anticorpo antifosfolípide (SAF), constituída por fenômenos tromboembólicos (FTE). A mutação Val247Leu no V domínio da β2GP1 - substituição da leucina por valina - expõe epítopos crípticos com consequente formação de anticorpos antiβ2GP1. OBJETIVO: Avaliar a associação do polimorfismo Val247Leu do gene β2GP1 com títulos de anticorpos antiβ2G… Show more

“…Mutation of a domain V gene that exchanges leucine for valine at position 247 (val247leu in place of val247val) causes structural modification in the protein. A recent study concluded that leprosy patients homozygous for val247val have a greater tendency to produce the pathogenic β 2 GPI-dependent aPL [6].…”
