In this relaunch issue of Psychiatric Genetics, we sought to present a series of reviews that summarise the state of the field. The topics of these reviews cover some of the many areas of Psychiatric Genetics that Dr John I. Nurnberger Jr. has studied over the years. I would like to take this opportunity to thank Dr Nurnberger for his excellent stewardship of the journal and for giving me the opportunity to act as Editor in Chief.

Dr Nurnberger will maintain his links with the journal by acting as Senior Editor alongside Associate Editor, John Vincent, and Mirko Manchia, who is the Review Editor.

Modern genetics is moving at an incredible pace, and it is important that journals such as ours keep pace with the expectations and norms in the field. I would like to emphasise the importance of adequate statistical power in studies in order to add value to the scientific knowledge. Of course, this does mean that well-designed experiments may not produce the expected results; however, it is important that such findings are made publicly available through the peer-reviewed publication process.

As a journal, Psychiatric Genetics has been an ardent supporter of studies performed in the developing world on populations that are not widely represented in large-scale studies. We continue to believe that such studies are important; however, we would strongly encourage collaboration amongst investigators who have access to these types of samples in order that studies are appropriately powered. We also encourage studies that attempt to replicate robust findings from the literature because these have great potential to inform the field on how particular variants may play a role in risk of mental illness across global populations. We would also like to encourage studies that seek to develop an understanding of the functional consequences of risk variants for psychiatric disorders.

Finally, I would also like to take this opportunity to thank the many reviewers who have taken the time to review manuscripts for the journal.
