MARKER AND METHOD FOR DIAGNOSING DIARRHEA SYNDROME

摘要

The present invention relates in a first aspect to new nucleic acid molecules and peptides identifying and diagnosing diarrhea syndrome including chronic diarrhea and bowel diseases. In addition, methods are provided for identifying or diagnosing a potential risk for developing or having a diarrhea syndrome comprising identifying in a sample from a subject the presence or absence of a mutation at position 2519 of the gene encoding GC-C. Moreover, a kit is provided allowing identification or diagnosing a diarrhea syndrome including probes allowing the detection of mutations at position 2519 of the nucleic acid sequence encoding GC-C or for detecting a mutation at position 840 of GC-C. Moreover, a method for screening and/or identifying candidate molecules useful in prophylactically or therapeutically treating said diseases is provided. Finally, the present invention relates to metformin and/or a pharmaceutically acceptable salts thereof for use in the prophylactic or therapeutic treatment of diarrhea syndrome.
