As these genes are related to nervous system or human mental disorders, 10 candidate genes, i.e., THOC1, ASIC2, LLPH, RFX8, MSRB3, CHL1, JAK2, MEIS1, LRRTM4, and ACSS3, were used for further analysis in a single-cell expression database of human neural developmental. The gene discussed is MEIS1; the disease is psychiatric disorder.
