For example, four single-nucleotide polymorphisms (SNPs) (rs2237717, rs41735, rs42336, and rs1858830) of the MET gene and the rs1130233 SNP of the AKT1 gene have been associated with schizophrenia [9-11] and with neurocognitive performance [9,11]. This evidence concerns the gene AKT1 and schizophrenia.
