Abstract
Described herein are assays, kits and methods for treating mood disorders by testing for one or more polymorphisms in a specific group of genes and for analyzing the results of polymorphism testing; the genes included may converge in one or more signaling pathways, and may be epigenetic. The genes are included based on the relationships of the proteins encoded by the genes in the context of particular signaling pathways and provide a diagnostically relevant nexus. Also described herein are methods of presenting the data collected by the screen, including methods of delivering interpretive comments and/or treatment guidance based on the results of the genetic screening either individually or based on the genetic composition of particular clusters of genes which may be related to each other. Importantly, drugs which modulate these genetic disturbances are described for targeted therapeutic use based upon companion diagnostic method.

14. A mood disorder panel assay to guide therapeutic treatment by determining the presence of SNPs that alter the function or expression of:
- the SERT gene;
one or more of;
DRD2, MTHF, COMT genes;
one or more of;
CACNA1C; and

-
15. A mood disorder panel assay to determine the presence of SNPs that contribute to a mood disorder, the panel assay comprising:
-
a plurality of SNP indicators that collectively indicate the presence or absence of one or more SNP that alters the function or expression of a gene from each of the serotonin metabolism pathway, the dopamine metabolism pathway, the glutamate metabolism pathway, and the hypothalamic pituitary adrenal axis; and an interpretive comment suggesting a treatment based on the identified SNPs.

16. A method of treating a patient for a mood disorder comprising:
-
determining the genotype of a polymorphism in each of the SERT, BDNF, CACNA1C, MTHFR/COMT and DRD2 genes; advising a treatment based upon the results of said testing.
