Methods and compositions for the treatment of psychotic disorders through the identification of the SULT4A1-1 haplotype
Methods and compositions that relate to genetic markers of psychotic disorders, e.g., schizophrenia (SZ), are provided. For example, in certain aspects methods for determinations of a SULT4A1-1 haplotype are described. Furthermore, the invention provides methods and compositions involving treatment of psychotic disorders using the haplotype status.
1. A method for treating a human subject having or suspected of having a psychotic disorder comprising:
a) selecting a subject that has been determined to have a SULTA1-1 haplotype, wherein the SULTA1-1 haplotype is defined as a haplotype comprising a C allele at rs763120, a combination of an A allele at rs2285162 and a G allele at rs2285167, or the combination of a T allele at rs2285166 and G allele at rs2285167, and treating the subject that has the SULT4A1-1 haplotype with quetiapine or olanzapine; or
b) selecting a subject that has been determined not to have the SULT4A1-1 haplotype and treating the subject that does not have the SULT4A1-1 haplotype with an anti-psychotic treatment other than quetiapine or olanzapine.
2. The method of claim 1 , wherein the subject comprises the SUTL4A1-1 haplotype and the subject is treated with quetiapine.
3. The method of claim 1 , wherein the subject comprises the SUTL4A1-1 haplotype and the subject is treated with olanzapine.
4. The method of claim 1 , wherein the subject does not comprise the SULT4A1-1 haplotype and the subject is treated with an anti-psychotic treatment other than quetiapine or olanzapine.
5. The method of claim 4 , wherein the anti-psychotic treatment other than quetiapine or olanzapine is risperidone.
6. The method of claim 4 , wherein the anti-psychotic treatment other than quetiapine or olanzapine is perphenazine.
7. The method of claim 4 , wherein the anti-psychotic treatment other than quetiapine or olanzapine is ziprasidone.
8. The method of claim 1 , wherein the psychotic disorder is schizophrenia.
