Methods and compositions for the treatment of psychotic disorders through the identification of the SULT4A1-1 haplotype
Methods and compositions 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 genotyping a subject to determine the presence of a haplotype comprising the steps of:
(a) obtaining a biological sample comprising genetic material of the subject, wherein the subject is undergoing or is to undergo anti-psychotic pharmacotherapy; and
(b) determining the presence of a SULT4A1-1 haplotype in the biological sample, wherein the SULT4A1-1 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.
2. The method of claim 1 , further comprising recording the determination of the haplotype in a tangible medium.
3. The method of claim 2 , wherein the tangible medium comprises a computer-readable disk, a solid state memory device, or an optical storage device.
4. The method of claim 1 , further comprising extracting DNA from the biological sample.
5. The method of claim 1 , wherein the genetic material is analyzed by SNP genotyping or sequencing.
6. The method of claim 1 , further comprising reporting the determination to the subject, a health care payer, a physician, a pharmacist, a pharmacy benefits manager, or an electronic system.
7. The method of claim 1 , wherein the determining step is carried out through the use of an array or a kit comprising a plurality of primers or probes specific for the SULT4A1-1 haplotype, wherein the SULT4A1-1 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.
8. The method of claim 1 , wherein the subject is undergoing or is to undergo antipsychotic treatment with olanzapine, risperidone, quetiapine, or perphenzazine.
