Abstract:
Described are general means and methods of diagnosing and treating the phenotypic spectrum as well as the overlapping clinical characteristics with several forms of inherited abnormal expression and/or function of the CYP3A4 and CYP3A7 genes. In particular, polynucleotides of molecular variant CYP3A4 and CYP3A7 genes which, for example, are associated with insufficient metabolization and/or sensitivety of drugs, and vectors comprising such polynucleotides are provided. Furthermore, host cells comprising such polynucleotides or vectors and their use for the production of variant CYP3A4 and CYP3A7 proteins are described. In addition, variant CYP3A4 and CYP3A7 proteins and antibodies specifically recognizing such proteins as well as transgenic non-human animals comprising the above-described polynucleotides or vectors are provided. Described are also methods for identifying and obtaining inhibitors for therapy of disorders related to the malfunction of the CYP3A4 and CYP3A7 genes as well as methods of diagnosing the status of such disorders. Pharmaceutical and diagnostic compositions comprising the above-described polynucleotides, vectors, proteins, antibodies and inhibitors by the above-described method are provided. Said compositions are particularly useful for diagnosing and treating various diseases with drugs that are substrates, inhibitors or modulators of the CYP3A4 or CYP3A7 gene product.
Abstract:
Provided are polynucleotides of molecular variant promoters of the CYP2D6 gene which, for example, are associated with abnormal drug response or individual predisposition to several common diseases and disorders caused by drug under- or over-metabolization, and vectors comprising such polynucleotides.

Abstract:
The present invention relates to the use of "setrones" for the preparation of a pharmaceutical composition for treating and/or preventing "setrone-treatable diseases" in a patient having a genotype with a first or second variant allele which comprises a polynucleotide in accordance with the present invention. Preferably, a nucleotide deletion, addition and/or substitution comprised by said polynucleotide results in an altered expression of the first and/or second variant allele compared to the corresponding wild type allele or an altered activity of the polypeptide encoded by the variant allele compared to the polypeptide encoded by the corresponding wild type allele. Finally, the present invention relates to a method for selecting a suitable therapy for a subject suffering from "setrone-treatable diseases as well as to methods of treatment for treating and/or preventing "setrone-treatable diseases" .
Abstract:
