In the current study, we have expanded our previous studies to examine the protein and mRNA expression of two novel GABAA receptors, theta (GABRθ) and rho 2 (GABRρ2) as well as FMRP, and metabotropic glutamate receptor 5 (mGluR5) in lateral cerebella of subjects with schizophrenia, bipolar disorder, major depression and healthy controls, and in superior frontal cortex (Brodmann Area 9 (BA9)) of subjects with schizophrenia, bipolar disorder and healthy controls.
Major depression in females with the FMR1 premutation may not be characterized as an episodically chronic recurrent disorder as it is in community samples and may have a genetic basis given the relationship with CGG repeat length and lack of association with all child and most demographic factors.
