We reasoned that the pronounced deficits in cellular phenotypes, observed in schizophrenia patient-derived iPS cells with GLO1 frameshift mutation might be contributed by the additional schizophrenia-associated genetic risk factors in the subject (Toyosima et al, 2011; Balan et al, 2014; Toyoshima et al, 2016). Here, GLO1 is linked to schizophrenia.
