  • Publication number: 20110229892
    Abstract: A method of predicting responsiveness of a subject to a folylpolyglutamate synthetase (FPGS) dependent anti-folate is provided. The method comprises analyzing for a presence or absence of a splice variant of FPGS or a polypeptide encoded thereby, in a sample of the subject, wherein the presence of the splice variant or the polypeptide encoded thereby is indicative of a negative response to a FPGS-dependent anti-folate. Kits for prediction responsiveness of a subject to FPGS-dependent anti-folate are also disclosed. Antibodies specific for splice variants, the splice variant nucleic acids and polypeptides encoded by the splice variants are also claimed. In particular splice variants missing exons selected from the group of exon 3, exon 7, exon 10 and exon 12 are disclosed.
