Az 1-es típusú neurofibromatosis autoszomális dominánsan öröklődő hamartosis, hátterében a neurofibromin-1 gén mutációi állnak. A változatos klinikai kép jellegzetességei a café-au-lait foltok, a bőr jóindulatú neurofibromái, az axillaris, inguinalis hiperpigmentációk, az íriszhamartomák, a csontrendszer deformitásai, valamint a neoplazmák kialakulásának veszélye. A neurofibromin-1 gén eltérései az esetek 50%-ában de novo mutációra vezethetőek vissza. Célkitűzés: Intézetünk 2008 óta végzi a neurofibromin-1 gén molekuláris genetikai vizsgálatát, e közleményben a tapasztalatok kerülnek összefoglalásra. Módszerek: Negyven, a neurofibromatosis klinikai tüneteit mutató beteg teljes génszekvenálása vagy multiplex ligatiofüggő amplifikációval való vizsgálata történt. Eredmények: A kóroki eltérést 31 esetben sikerült azonosítani, 8 betegben az irodalomban eddig nem ismert mutáció került detektálásra. A 8 érintettből, akiknél szekvenálással nem sikerült azonosítani a kóroki mutációt, 1 esetében egy, a teljes gént érintő deletio igazolódott. Következtetések: A neurofibromin-1 gén teljes szekvenálása a nagyobb génátrendeződések vizsgálatával kiegészítve az esetek nagy többségében alkalmas a kóroki eltérés azonosítására. Orv. Hetil., 2011, 152, 415–419.
