A recent study of de novo mutations found in multiple neurodevelopmental disorders revealed that MYH9 (Box 2) is one of only three affected genes shared by autism, schizophrenia and intellectual disability, and de novo mutations for MYH10 (Box 2) are reported for both schizophrenia and autism (Li et al., 2015b). This evidence concerns the gene MYH9 and schizophrenia.
