The Section Genetics in Psychiatry of the World Psychiatric Association (WPA) prepared a booklet with recommendations on genetics and pharmacogenetics in psychiatry. It contains a short outline of the Open-Access clinical guideline for psychiatrists authorized by the Dutch Psychiatric Association in 2020 to bridge the gap between the already available more technical guidelines and application in clinical practice. Simple and easy-to-apply information is available that clinicians can adopt in their clinical practice without having to read through full texts on different websites or scientific publications.
