Abstract
The invention relates to a method for the prediction of the risk potential and/or diagnosis of cancerous diseases or inflammatory intestinal diseases, whereby a DNA sample is tested for the presence of polymorphic UGT1A7 allele. A positive result for a mutation is a positive indication of a sensitivity to cancerous diseases. A prediction of sensitivity to an inflammatory intestinal disease can similarly be made. A PCR amplification of the exon 1, using the DNA sample with subsequent sequence analysis is carried out in the method and the determined sequence compared with that of the wild type and the polymorphic allele. The presence or lack of mutations is monitored by sequencing the corresponding cDNA using automated fluorescent dye sequencing. The test arrangement for requires genetic detection reagents, namely the required primer or cDNAs, on a stationary support in a pre-prepared arrangement or sequence for reading off the results. The recombinant UGT1A7 enzymes are also used for therapeutic purposes.
