First Claim
Patent Images
1. A method for predicting likelihood of a patient responding to treatment with an atypical antipsychotic drug selected from the group consisting of Paliperidone, and pharmaceutically acceptable salts and esters thereof, comprising:
- a) analyzing nucleotide sequences of two alleles of the ErbB4 gene in said patient;
b) determining a genotype at a polymorphic site in the ErbB4 gene, wherein said polymorphic site is at 201 in SEQ ID NO;
1; and
c) identifying the patient with the genotype of GA or GG as being more likely to respond to the drug, and the patient with the genotype of AA as being less likely to respond to the drug.

Abstract
The present application is directed to the use of genetic polymorphism in the ErbB4 gene to predict whether a patient is likely to respond to psychotic medication Paliperidone. The polymorphism in the ErbB4 gene is also used to predict whether a patient is likely to display placebo effect among patients in need of psychotic treatment. A method of treating patients with antipsychotic medication Paliperidone using the polymorphism in the ErbB4 gene and a kit of are also provided.
