Fear-specific amygdala function in children and adolescents on the fragile X spectrum: a dosage response of the FMR1 gene (original) (raw)
Mutations of the fragile X mental retardation 1 (FMR1) gene are the genetic cause of fragile X syndrome (FXS). The presence of significant socioemotional problems has been well documented in FXS although the brain basis of those deficits remains unspecified. Here, we investigated amygdala dysfunction and its relation to socioemotional deficits and FMR1 gene expression in children and adolescents on the FX spectrum (ie, individuals whose trinucleotide CGG repeat expansion from 55 to over 200 places them somewhere ...
