Genetic and functional study of the IPO5 gene in schizophrenia.

The present work reported on a weak association of the importin 5 (IPO5) gene with schizophrenia in combined family and case-control samples and also investigated a possible mechanism by which the IPO5 gene may contribute to the development of the disease in a Chinese population. Our results suggest that abnormal expression and alternative splicing of the IPO5 gene may be involved in the pathophysiology of schizophrenia.
