Within the CGE, genes with high expression specificity for two calretinin (CALB2)-positive sub-populations of developing GABAergic neurons were also enriched for schizophrenia genetic liability (CGE-N-1, marker: NRIP3, and CGE-N-2, markers: BEX2, ARL6IP5, VSTM2A; Supplementary figure S7B). This evidence concerns the gene ARL6IP5 and schizophrenia.
