    • The present invention discloses a novel single nucleotide polymorphism (SNP) in the isolated 5′ tandem repeats of the thymidylate synthase (TS) gene and methods for its use. The novel SNP, located in the 12th nucleotide of a 28 bp third tandem repeat (3R) of the TS gene, substitutes a C for a G, and is the variant form of the repeat. Subjects with the wild-type form of 3R have greater transcription of the TS gene than subjects with the variant form. The invention also reveals that a six base pair deletion in the 3′ region of TS (−6 bp/1494) indicates mRNA instability and thus reduced production of TS. In diseased tissue, such as cancer, reduced production of TS is beneficial because it prevents the cancerous cells from growing and spreading. Analysis of either polymorphism or both together allows for prediction of a subject's response to chemotherapeutic and anti-cardiovascular disease treatments because both diseases are related to TS levels in a subject.
    • 本发明公开了在胸苷酸合酶(TS)基因的分离的5'串联重复中的新型单核苷酸多态性(SNP)及其使用方法。 位于TS基因的28bp第三串联重复(3R)的第12个核苷酸的新型SNP代替C代表G,并且是重复的变体形式。 具有野生型形式的3R的受试者比具有变体形式的受试者具有更高的TS基因转录。 本发明还揭示了在TS(-6bp / 1494)的3'区域中的6个碱基对缺失表示mRNA不稳定性,从而降低TS的产生。 在患病组织如癌症中,减少TS的产生是有益的,因为它可防止癌细胞生长和扩散。 多态性或两者的分析可以预测受试者对化学治疗和抗心血管疾病治疗的反应,因为这两种疾病都与受试者的TS水平相关。
