Rare variants of ERBB4 have been associated with increased risk for schizophrenia [32]; an intronic deletion between exons 7 and 8 was also identified in a patient with an ASD [33]; and a patient with a de novo reciprocal translocation t(2;6)(q34;p25.3), apparently disrupting the ERBB4 gene, was identified with early myoclonic encephalopathy [34]. Here, ERBB4 is linked to schizophrenia.
