Infos zur Erkrankung
Systemischer Lupus erythematodes (SLE) ist eine komplexe Autoimmunerkrankung, die durch die Produktion von Autoantikörpern gegen Moleküle im Zellkern, im Zytoplasma und auf der Zelloberfläche gekennzeichnet ist, die organspezifische Grenzen überschreiten. Die Ablagerung von Antikörpern oder Immunkomplexen im Gewebe führt zu Entzündungen und anschließenden Verletzungen mehrerer Organe und führt schließlich zu klinischen Manifestationen von SLE, darunter Glomerulonephritis, Dermatitis, Thrombose, Vaskulitis, Krampfanfälle und Arthritis. Es gibt starke Hinweise darauf, dass genetische Komponenten an der SLE-Anfälligkeit beteiligt sind im Sinne einer multifaktoriellen/polygenen Ätiologie. Es werden jedoch auch monogene Formen beobachtet; mindestens 7% aller SLE-Fälle mit Krankheitsbeginn im Kindesalter sind durch die Wirkung eines Einzelgens bedingt. Es werden autosomal-rezessive und X-chromosomal dominante Erbgänge beobachtet.
