Calbindin-containing γ-aminobutyric acid (GABA)ergic interneurons in the prefrontal cortex (PFC) have been found to play an important role in working memory (WM) and their malfunctions have been linked to psychiatric disorders.
We explored the possible genetic causalities that may underlie the cytoarchitectural abnormalities of calbindin-containing γ-aminobutyric acid (GABA)ergic neurons and perineuronal oligodendrocytes in the PFC of subjects with psychiatric disorders by converging results from genome-wide single-nucleotide polymorphism (SNP) scans for the traits and expression SNP (eSNP) associations.
These findings may provide novel insights into the molecular mechanisms that underlie the cytoarchitectural abnormalities of perineuronal oligodendrocytes and calbindin-containing GABAergic interneurons in the prefrontal cortex of the major psychiatric disorders.
