The present invention is directed to polymorphisms in the MME gene (encoding metalo-membrane endopeptidase, neutral endopeptidase (NEP), enkephalinase) and the ANPEP gene (encoding amino peptidase N (APN), alanyl membrane aminopeptidase) or their gene products and to a process for the diagnosis of internalizing disorders. Internalizing disorders, such as depression, withdrawal, negative affect, anxiety, social problems, phobias, paranoid ideation, alcoholism and interpersonal sensitivity, are diagnosed in accordance with the present invention by analyzing the DNA sequences of the MME and/or ANPEP genes of an individual to be tested and comparing the respective DNA sequence to the known DNA sequence of a normal MME and/or ANPEP gene. Alternatively, the MME and ANPEP genes of an individual to be tested can be screened for mutations which cause internalizing disorders. Prediction of internalizing disorders will enable practitioners to treat internalizing disorders using existing medical therapy.
A method for diagnosing a polymorphism which causes an internalizing disorder comprising hybridizing a nucleic acid probe which hybridizes specifically to a nucleic acid selected from the group of (a) a nucleic acid comprising a nucleotide sequence coding for human MME containing a polymorphism described herein or its complement and (b) a nucleic acid comprising a nucleotide sequence coding for human APN containing a polymorphism described herein or its complement to a patient's sample of DNA or RNA under stringent conditions which allow hybridization of said probe to nucleic acid comprising said polymorphism but prevent hybridization of said probe to a wild-type nucleic acid, wherein the presence of a hybridization signal indicates the presence of said polymorphism.
A method for diagnosing the presence of a polymorphism in human MME or ANPEP which causes an internalizing disorder wherein said method is performed by means which identify the presence of a polymorphism selected from the group described herein.
An antibody which binds to a polymorphic APN polypeptide but not to wild-type APN polypeptide, wherein said polymorphic APN has an altered sequence as disclosed herein.
An isolated polypeptide an amino acid sequence of APN with a polymorphism described herein.
A host comprising a nucleic acid selected from the group of (a) a nucleic acid comprising a nucleotide sequence coding for human MME containing a polymorphism described herein or its complement and (b) a nucleic acid comprising a nucleotide sequence coding for human APN containing a polymorphism described herein.
A method of correlating a placebo response to a polymorphism described herein which comprises i.providing a placebo to a cell or animal having said polymorphism and detecting whether a placebo response is present, whereby the presence or absence of a placebo response is correlated to the said polymorphism.
A method of correlating a polymorphism described herein with a drug that inhibits the activity of NEP which comprises providing said drug to a cell or animal having said polymorphism and detecting inhibition of NEP, whereby inhibition of NEP is correlated to said polymorphism and said drug is useful for treating a disorder associated with said polymorphism.
A method of correlating a polymorphism described herein with a drug that inhibits the activity of APN which comprises providing said drug to a cell or animal having said polymorphism and detecting inhibition of APN, whereby inhibition of APN is correlated to said polymorphism and said drug is useful for treating a disorder associated with said polymorphism.
A method to screen for drugs which are useful in treating a person with an internalizing disorder from a polymorphism in MME and/or ANPEP as described herein, wherein said method comprises providing said drug to a cell or animal having said polymorphism and detecting inhibition of NEP and/or APN, whereby inhibition of NEP and/or APN is indicative that said drug is useful for treating a disorder associated with said polymorphism.
A method to screen for drugs which are useful in treating or preventing an internalizing disorder, said method comprising:
