SLC6A4 |
L(A)/S |
Associated with poor response, slow response, and adverse events with SSRI medications test |
Caution with: SSRIs |
5HT2C |
C/C |
Associated with increased incidence of weight gain and metabolic syndrome with atypical antipsychotics |
Caution with: atypical antipsychotics Therapeutic options: myo-inositol |
CACNA1C |
G/A |
Common variations shows very modest association to schizophrenia and bipolar disorder, but is not
diagnostic for either disorder and is also observed in individuals without those disorders |
Therapeutic options: mood stabilizers, atypical antipsychotics, omega-3 fatty acids |
MTHFR |
C/T |
Patients with the T allele have reduced enzyme activity resulting in reduced conversion of folic acid/folate to
methylfolate. Methylfolate is a precursor to serotonin, norepinephrine, and dopamine synthesis |
Therapeutic options: l-methylfolate |
CYP2D6 |
Poor metabolizer (PM) [low activity] *4/*4 |
Increased risk of elevated serum levels, drug interactions, and reduced production of active moieties |
Use increased caution when prescribing substrates in patients who are poor or intermediate metabolizers and, if clinical response and/or blood levels warrant, a dose adjustment may be considered |
