The top gene of the novel subset was MON1A, a gene believed to be involved in protein secretion that has been implicated in a number of other cognitive traits, including occupational attainment (Ko et al. 2022), household income (Hill et al. 2019a, b), intelligence (Hill et al. 2019a, b), creativity (Kim et al. 2024), and schizophrenia (Lam et al. 2019). This evidence concerns the gene MON1A and schizophrenia.
