Auto-active and intracellular mutant of MET
The present invention relates to the fields of medicine and molecular diagnostics. In particular, it relates to a novel method for the treatment, prevention and/or delay of cancer and to a diagnostic method involving detection of a novel auto-active and intracellular mutant of MET.
1. A method for detecting a deletion in the MET gene in a human subject, comprising,
(a) obtaining a nucleic acid sample from the subject, wherein the sample comprises genomic DNA and/or mRNA
and
(b) screening genomic DNA encoding the MET gene using a molecular diagnostic method and detecting the presence of a chromosomal deletion in the MET gene, wherein the deletion consists of loss of part of intron 6, exon 7, and part of exon 8 of the MET gene in the subject and/or
(c) screening mRNA or cDNA from the MET gene using a molecular diagnostic method and detecting the presence of a deletion which consists of the substantial absence of exons 7 and 8 of the MET mRNA or cDNA.
2. The method of claim 1 , wherein the molecular diagnostic method is a nucleic acid detection assay comprising an oligonucleotide, wherein a complex of the oligonucleotide with a template polynucleotide is formed.
3. The method of claim 1 , wherein the subject has a condition selected from amyotrophic lateral sclerosis, systemic sclerosis, ulcerative colitis, autism and/or a cancer selected form the group consisting of lymphoma, leukemia, mycosis fungoide, carcinoma, adenocarcinoma, sarcoma, rhabdomyosarcoma, Ewing sarcoma, castration resistant prostate carcinoma, glioma, astrocytoma, blastoma, neuroblastoma, plasmacytoma, histiocytoma, melanoma, adenoma, hypoxic tumor, myeloma, metastatic cancer, bladder cancer, brain cancer, nervous system cancer, squamous cell carcinoma of the head and neck, neuroblastoma, glioblastoma, ovarian cancer, skin cancer, liver cancer, squamous cell carcinomas of the mouth, throat, larynx, and lung, colon cancer, cervical cancer, breast cancer, cervical carcinoma, epithelial cancer, renal cancer, genitourinary cancer, pulmonary cancer, esophageal carcinoma, lung cancer, head and neck carcinoma, hematopoietic cancer, testicular cancer, colorectal cancer, prostatic cancer, and pancreatic cancer.
4. The method according to claim 1 , wherein the sample is tissue, a tumor tissue, urine, sperm, saliva, blood, blood plasma, cerebrospinal fluid, blood platelets, and/or exosomes.
