GeneSight Reviews: What You Should Know Before Buying

About Genesight

GeneSight, founded in 2014, is a clinical genomic testing company that analyzes how genes influence your responses to mental health medications.

This pharmacogenomics company attempts to provide DNA-based recommendations for certain medications.

GeneSight is a part of a biogenetic company, Myriad Genetics. Myriad was founded by previous CEO and President Peter Meldrum, Walter Gilbert, Kevin Kimberlum, and Mark Skolnick. It is currently led by CEO and President Paul J Diaz.

Overview of GeneSight Services

GeneSight offers 2 tests for its users:

The GeneSight Psychotropic Test

The GeneSight Psychotropic test examines your genetic makeup and provides insights into how likely your body may respond to medications that are used to treat mental health conditions like depression, anxiety, and ADHD.

This information can help your clinician alter your dosages and recommend an alternative drug, if required, to minimize the side effects.

The GeneSight MTHFR Test

MTHFR (methylenetetrahydrofolate reductase) enzyme is very crucial for converting the inactive form of vitamin B9, folate, or folic acid, to the active form.

The active form is called L-methylfolate. This test examines whether a person carries any changes in the MTHFR gene that may interfere with conversion and lead to vitamin B9 or folate deficiency.

GeneSight: How to Order?

Users cannot directly place an order for the DNA test kit. It must be done through a doctor or nurse practitioner.

Specimen collection (cheek swab) can either be done by the clinician or at home — in the latter case, your clinician can have the kit directly shipped to your home.

Once the sample is collected, it needs to be sent to the lab for analysis. The results are typically available after 2 days.

The results are sent to the healthcare provider who placed the order. Only after they consult with the company to understand the information can they communicate the results to their patients.

Overview of Genesight Reports

The genetic testing reports differ for the two tests.

GeneSight Psychotropic Report

The 12-page Psychotropic Report analyzes two sets of genes to provide information on how likely you are to respond to certain medications.

Pharmacokinetic Genes

These genes influence how your body acts upon medications; they influence the transport and metabolism of the drugs.

- CYP1A2
- CYP3A4
- CYP2D6
- CYP2C19
- CYP2C9
- CES1A1
- CYP2B6
- UGT1A4
- UGT2B15

Pharmacodynamic Genes

These genes influence how the medication may affect the body — side effects, risk of addiction, etc.

- SLC6A4
- HLA-A*3101
- HLA-B*1502

The first few pages of the report categorize different drugs based on how the genetic influence exerted on them:

Use As Directed: No known association with genetic issues

Moderate Gene-Drug Interaction: Maybe less likely to work or less efficient

Significant Gene-Drug Interaction: Maybe less likely to work and may cause side effects

It is followed by the “Clinical Considerations” section to be reviewed by the clinician. The clinical considerations explain why a medication is listed in a particular category and how it must be administered if the patient wishes to pursue the treatment.

The following two pages provide information about the genotypes and phenotypes of the patients, which are of medical importance.

The first page contains information about pharmacodynamic genes and their relation to specific disorders.

The second page contains the same information regarding pharmacokinetic genes.

The report also includes information on other genotypes that do not have a strong association with medication outcomes.

The last section of the report is the “Gene-drug Interactions.” This is a comprehensive overview of which genes interact with which drugs and affect their functioning. The section is broken down into 3 segments — Use as directed, Moderate gene-drug interaction, and Significant gene-drug interaction.

A filled circle means that the particular gene interacts with the functioning of that particular drug. An empty circle indicates no interaction.

GeneSight MTHFR Report

The compact 1-page MTHFR Report isn’t all that informative. It reports the patient’s MTHFR genotype along with how efficiently they convert inactive folic acid to active folic acid or L-methylfolate.

GeneSight Pricing

GeneSight claims that 95% of their users pay $330 or less for the test. If the cost exceeds that amount, the company will call the patients.

Medicare/Medicaid — Full testing cost covered

Medicare Advantage Covered Tests and Other Insurance — You may need to pay $330 or less

Uninsured — Cost varies — financial assistance may be provided for some

Once they receive the sample, the cost is confirmed. If it exceeds $330, the patients receive a call from the company. The company then submits the claim to the insurance company and checks for eligibility for financial assistance. Patients then receive an explanation of benefits from their insurance company before receiving a bill.
