'Jumping Genes' Linked to Schizophrenia


More articles on this same science news story:


Genetic sequences called transposable elements (TEs) that can jump from chromosome to chromosome, increasing their own frequency in the genome, may play a role in the development of schizophrenia, according to a study out of the RIKEN Brain Science Institute in Japan published last week (January 2) in Neuron.

Schizophrenia runs in families, suggesting it has an underlying genetic basis. Identifying genes with a strong role in the disorder’s development, however, has proven difficult. Environmental factors are also expected to contribute.
