Details and patient eligibility

About

Genotype 164 adults to evaluate six selected single nucleotide polymorphisms (SNPs) (rs1006737, rs10994336, rs10994133, rs2238071, rs1051375, rs1024582) for use as a genetic biomarker to differentiate between bipolar depression and unipolar depression.

Full description

Adults ages 18-80 will be recruited if they are diagnosed with bipolar disorder, major depression, or have no mood symptoms. The adults will undergo a diagnostic interview, the Mini International Neuropsychiatric Interview (MINI) for the diagnosis. The subjects will also complete the Adverse Childhood Events Scale to evaluate for a genetic x environmental interaction in detecting bipolar disorder at initial assessment. Genotyping will be done by SNaPshot genotyping method and genetic sample will be collected via buccal swab.

Enrollment: 164 patients
