The following chromosomes contain genetic information for creating specific proteins that may be implimented in the intergenerational transmission of PTSD and its related (comorbid) conditions. Evidence is emerging that indicates these candidate genes may also have an influence in conditions such as ADHD, Bipolar, Autism, Aspergers and others. Consider the facts: Segments of genes create proteins for everything possible in the human genome. All they need is a signal from another gene or the environment to turn them on, or off.

Look closely at what may 'run' in your family. There may be a way to eliminate or, at least, restrict its impact.
