Copy Number Variants: A Window into Psychiatric Illness

The human genome consists of nearly 25,000 protein-coding genes – and a mutation in just one of these can have dramatic effects on our brains.  Remarkably, one tiny change in our genes (which can be as small as 0.000000025 cm!) can lead to visible changes in our behavior.  Schizophrenia, autism, bipolar disorder, and ADHD have all been linked to variations in our DNA.  But how do changes in our genetic code result in these complex psychiatric disorders?Continue reading
