孤獨癥與7號染色體有關

www.www471818.com  2008-12-8 13:00:21  來源：不詳



　　 加拿大多倫多大學遺傳學者斯蒂芬·希勒等人的最新研究顯示，孤獨癥可能同患者7號染色體上的基因順序紊亂有關。
　　希勒和同事對約2000名孤獨癥患者的基因組成進行分析后發現，100多例與基因紊亂有關的基因變異發生在7號染色體處。發生變異的基因有兩類：與說話、交流相關的基因及控制神經元進行信息傳達的基因。希勒等人已經建立了一個動態數據庫，可供全球科研人員登錄。希勒認為，隨著存儲信息的增加，他們能夠發現更多的與7號染色體基因順序紊亂有關的基因變異，從而更迅速找到孤獨癥的基因根源。
