INDIVIDUAL AND COHORT PHARMACOLOGICAL PHENOTYPE PREDICTION PLATFORM
First Claim
1. A computer-implemented method for identifying lithium phenotypes, the method executed by one or more processors programmed to perform the method, the method comprising:
- identifying a plurality of SNPs correlated with lithium phenotypes;
comparing the plurality of SNPs to a database of SNPs to identify additional SNPs that are linked to the plurality of SNPs, wherein the plurality of SNPs and additional SNPs are included in a set of permissive candidate variants;
performing, by one or more processors, a bioinformatics analysis to filter the set of permissive candidate variants into a subset of intermediate candidate variants based on at least one of;
regulatory function, variant dependence, a presence of target gene relationships for the permissive candidate variants, or whether the permissive candidate variants are non-synonymous coding variants with a minor allele frequency; and
performing, by the one or more processors, a pathway analysis to filter the subset of intermediate candidate variants to generate a lithium response pathway associated with SNPs which are causally related to the lithium phenotypes.

Abstract
For patients who exhibit or may exhibit primary or comorbid disease, pharmacological phenotypes may be predicted through the collection of panomic data over a period of time. A machine learning engine may generate a statistical model based on training data from training patients to predict pharmacological phenotypes, including drug response and dosing, drug adverse events, disease and comorbid disease risk, drug-gene, drug-drug, and polypharmacy interactions. Then the model may be applied to data for new patients to predict their pharmacological phenotypes, and enable decision making in clinical and research contexts, including drug selection and dosage, changes in drug regimens, polypharmacy optimization, monitoring, etc., to benefit from additional predictive power, resulting in adverse event and substance abuse avoidance, improved drug response, better patient outcomes, lower treatment costs, public health benefits, and increases in the effectiveness of research in pharmacology and other biomedical fields.

13. A method for treating a patient comprising:
-
obtaining a biological sample of a patient; comparing or having compared the biological sample to a set of single nucleotide polymorphisms (SNPs) within a lithium response pathway having a plurality of SNPs each of which are causally related to lithium phenotypes; determining a dosage of lithium for administering to the patient based on the comparison; and administering the determined dosage of lithium to the patient. - View Dependent Claims (14, 15, 16, 17, 18)
