In particular, the expression levels of the murine orthologs of the two genes RAI1 (GeneID: 10743) and SREBF1 (6720), which were associated with schizophrenia [37]–[39], a phenotype absent from SMS and PTLS patients [33],[40],[41], show a strong relationship with gene dosage. The gene discussed is RAI1; the disease is schizophrenia.
