Abnormalities in neural processing of emotional stimuli in Williams syndrome vary according to social vs. non-social content

Karen E. Muñoz, Andreas Meyer-Lindenberg, Ahmad R. Hariri, Carolyn B. Mervis, Venkata S. Mattay, Colleen A. Morris, Karen Faith Berman
2010 NeuroImage  
Williams syndrome (WS) is a rare genetic disorder caused by the deletion of ~25 genes on chromosome 7q11.23 and is characterized by both hypersociability and increases in specific phobia and anticipatory anxiety regarding non-social entities or circumstances. Alterations in amygdala reactivity and prefrontal regulation consistent with the observed behavioral pattern of social versus non-social abnormalities have been previously demonstrated in individuals with WS . However, in that study, the

In the present study, we examined the performance of the same group of participants with WS and normal IQs during a more cognitively demanding task using the same scene stimuli as in the prior study. Confirming previous findings, the results indicated (a) a differential response of prefrontal regions as a function of task difficulty and (b) a persistently increased activation of the amygdala to non-social scenes by individuals with WS regardless of cognitive load. These data provide further evidence of disruption in amygdala-prefrontal circuitry in individuals with WS.

Effects of HTR1A C(−1019)G on Amygdala Reactivity and Trait Anxiety

2009 Archives of General Psychiatry  
Serotonin 1A (5-hydroxytryptamine 1A [5-HT(1A)]) autoreceptors mediate negative feedback inhibition of serotonergic neurons and play a critical role in regulating serotonin signaling involved in shaping the functional response of major forebrain targets, such as the amygdala, supporting complex behavioral processes. A common functional variation (C[-1019]G) in the human 5-HT(1A) gene (HTR1A) represents 1 potential source of such interindividual variability. Both in vitro and in vivo, -1019G

Thus, -1019G may contribute to relatively decreased serotonin signaling at postsynaptic forebrain target sites via increased negative feedback. To evaluate the effects of HTR1A C(-1019)G on amygdala reactivity and to use path analyses to explore the impact of HTR1A-mediated variability in amygdala reactivity on individual differences in trait anxiety. We hypothesized that -1019G, which potentially results in decreased serotonin signaling, would be associated with relatively decreased amygdala reactivity and related trait anxiety. Imaging genetics in participants from an archival database. Eighty-nine healthy adults. Consistent with prior findings, -1019G was associated with significantly decreased threat-related amygdala reactivity. Importantly, this effect was independent of that associated with another common functional polymorphism that affects serotonin signaling, 5-HTTLPR. While there were no direct genotype effects on trait anxiety, HTR1A C(-1019)G indirectly predicted 9.2% of interindividual variability in trait anxiety through its effects on amygdala reactivity. Our findings further implicate relatively increased serotonin signaling, associated with a genetic variation that mediates increased 5-HT(1A) autoreceptors, in driving amygdala reactivity and trait anxiety. Moreover, they provide empirical documentation of the basic premise that genetic variation indirectly affects emergent behavioral processes related to psychiatric disease risk by biasing the response of underlying neural circuitries.

Identification of neurogenetic pathways of risk for psychopathology

Patrick M. Fisher, Karen E. Muñoz, Ahmad R. Hariri
2008 American Journal of Medical Genetics. Part C, Seminars in Medical Genetics  
Imaging genetics has been a highly effective and increasingly applied strategy for identifying the impact of genetic polymorphisms on individual differences in neural circuitry supporting complex behaviors. The application of imaging genetics towards further elucidating neural circuitry associated with the pathophysiology of psychiatric illness is of particular interest given its potential to guide the development and improvement of current therapeutic methods. The identification of genetic

In the continued development of this technique, recent multimodal neuroimaging strategies and studies examining the effects of multiple genes in concert within large subject populations have shown promise in the development of a more complete understanding of the interrelationships between genes, brain function, behavior and associated risk for psychopathology.
