Brain Enriched Myelin Associated Protein 1 associates with a variety of aggressive tumors. In the brain, BCAS1 isrequired for myelination and is expressed in oligodendrocytes and Schwann cells, showing decreased expression in demyelination. Mice lacking BCAS1 showed schizophrenia-like behaviors. Exome sequencing confirmed association with autism. This evidence concerns the gene BCAS1 and schizophrenia.
