人類基因組計劃提出已初步解決人類染色體上的基因數(shù)目,以及堿基的精確測序和定位,。而新的HapMap計劃則主要是破譯基因組中SNP微小差異與疾病的關(guān)系,。生物谷以前有過相關(guān)報道:Nature:人類基因組遺傳整合圖譜HapMap被初步揭開,最新Hapmap又有新成果,,是基于全基因組的SNP調(diào)查,。越來越多的證據(jù)顯示SNP的copy數(shù)多少直接與疾病相關(guān),因此基于全基因組的SNP篩查對于疾病的預(yù)測十分重要,。
1月15日Nature Gentics上兩篇文章介紹相關(guān)研究成果,。這是HapMap組織在2006年的重要成果。
