13-三体综合征
第13号染色体多了一条。其核型有三种:①13-三体型占80%,核型为47,XX,+13;②易位型约占13%,多见有D组14号染色体易位,核型为46,XX(或XY)-14,+t(13q14q);③嵌合型约5%,13三体型与正常核型嵌合,核型为47,XX(XY)+13/46,XX(XY)。其临床表现严重,如头小,前额不发育、严重者全裂额露脑畸形,腭裂常见,“摇椅底足”,心脏、肠、肾、耳、指及生殖器畸形均可见。皮肤纹理异常为本病重要表现:轴三极高,呈“七”或“t”,指纹中,弓形纹比例较大,故TRC低于62%,患者双手呈通贯掌纹。智能障碍严重,存活的小儿可有癫痫样发作。此病死亡率高,约80%患儿6个月内死亡。
