    • A screening method for identifying an individual having a pre-disposition towards having a cancer is disclosed, which screening method comprises the steps of : (a) obtaining a test sample comprising a nucleotide sequence comprised in a gene in a gene in a base excision repair (BER) pathway of the individual or an amino acid sequence of a polypeptide expressed thereby; and (b) comparing a region of the test sample sequence with the corresponding region of the wild type sequence, whereby a difference between the test sample sequence and the wild type sequence signifies that the individual is pre-disposed to having the cancer; and wherein the difference comprises a specified variation. The specified variation can be the known mutation in the human MYH protein, G382D-hMYH or a nucleotide sequence encoding it, or it can be one or more novel variations, namely, Y165C, E466X, and Y90X, or the respective corresponding nucleotide sequences. The method is particularly suitable for determining a pre-disposition towards bowel cancer.
    • 公开了一种用于鉴定具有癌症预处理的个体的筛选方法,该筛选方法包括以下步骤:(a)获得包含基因切除修复基因中的基因中包含的核苷酸序列的测试样品 (BER)途径或由其表达的多肽的氨基酸序列; 和(b)将测试样品序列的区域与野生型序列的相应区域进行比较,由此测试样品序列和野生型序列之间的差异表示预先处置患有癌症的个体; 并且其中所述差包括指定的变化。 指定的变体可以是人MYH蛋白,G382D-hMYH或编码它的核苷酸序列中的已知突变,或者可以是一个或多个新的变体,即Y165C,E466X和Y90X,或各自相应的核苷酸序列。 该方法特别适用于确定对肠癌的预处理。
