Prats et al. (2022) linked the disruption of the Neuregulin/ERBB axis genes to the defects in white matter formation in the brain of European individuals, manifested in schizophrenia-spectrum and autism-spectrum disorders. The ERBB4 gene has been found to be associated with predisposition to schizophrenia: rs707284-G (intr), rs839523-G (intr), and rs7598440-A (intr)—in a Jewish population (Silberberg et al., 2006), rs2289086-T (intr)—in a Chinese Han population (Lu et al., 2010), and rs3748962-G (V1065V)—in an African American population (Nicodemus et al., 2006). The gene discussed is ERBB4; the disease is schizophrenia.
