Characterizing social behavior in genetically targeted mouse models of brain disorders.

Abstract

Fragile X syndrome, the leading inherited cause of mental retardation and autism spectrum disorders worldwide, is caused by a tandem repeat expansion in the FMR1 (fragile X mental retardation 1) gene. It presents with a distinct behavioral phenotype which overlaps significantly with that of autism. Emerging evidence suggests that tandem repeat polymorphisms (TRPs) might also play a key role in modulating disease susceptibility for a range of common polygenic disorders, including the broader autism spectrum of disorders (ASD) and other forms of psychiatric illness such as schizophrenia, depression, and bipolar disorder [1]. In order to understand how TRPs and associated gene mutations mediate..
