One gene, many neuropsychiatric disorders: lessons from Mendelian diseases

Zhu, Xiaolin, Need, Anna C, Petrovski, Slavé, Goldstein, David B·2014·Nature Neuroscience

Abstract

Recent human genetic studies have consistently shown that mutations in the same gene or same genomic region can increase the risk of a broad range of complex neuropsychiatric disorders. Despite the steadily increasing number of examples of such nonspecific effects on risk, the underlying biological causes remain mysterious. Here we investigate the phenomenon of such nonspecific risk by identifying Mendelian disease genes that are associated with multiple diseases and explore what is known about the underlying mechanisms in these more 'simple' examples. Our analyses make clear that there are a variety of mechanisms at work, emphasizing how challenging it will be to elucidate the causes of nonspecific risk in complex disease. Ultimately, we conclude that functional approaches will be critical for explaining the causes of nonspecific risk factors discovered by human genetic studies of neuropsychiatric disorders.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
