I have long been skeptical of efforts to find a single gene or gene mutation relevant to any particular mental illness. After decades’ worth of such research, we are seemingly no closer to finding such genes or gene mutations. It is a frustrating effort.
As I wrote five years ago, genes and gene mutations for schizophrenia don’t seem to really help our understanding of the underlying causes of this disorder. They have, however, been extremely successful in showing how incredibly complex a disorder like schizophrenia really is.
New research published in Nature lends further evidence to this complexity. The combined effects of many genes and gene mutations are implicated in schizophrenia.
