Study: Dyskinesia Offers Few Clues to Schizophrenia Genetics

Involuntary movement abnormalities in patients with schizophrenia reflect experiences that are unique to the individual rather than an underlying genetic liability to the condition, research suggests.

A team at the University of Pittsburgh in Pennsylvania, USA, hypothesized that spontaneous dyskinesia would be apparent in the siblings of schizophrenia patients but not in unrelated controls.

Wring in the journal Schizophrenia Research, Sarah Tarbox and co-authors explain: “Several factors suggest that spontaneous dyskinesia maybe a useful supplemental phenotype for further elucidating the specific nature of the genetic contribution to schizophrenia.”
