A recently published study discussed the role of the ADRA2B gene in making someone more likely to pay attention to negative rather than positive visual stimuli. I'm wondering whether this relationship has been explored with regard to ASDs.
Dear Julie,
like to know,the gene in question is the Adra2b deletion variant,which influences the hormone and neurotransmitter norepinephrine.Previously found to play a role in the formation of emotional memories,the new study shows that the ADRA2b deletion variant olso plays a role in real-time perception.A new study by University of British Columbia,published in Psychological Science,found that a previously known gene variant con cause individuals to perceive emotional event (especially negative ones) more vividly than others
About "ASDs" are interesting,but not specific this papers:
Pharmacogenomics J.2013,Jul.16
J.Child Pschol.Psychiatry 2013,Jun 28
Olso for the ADRA2bgene are knowed the association between common genetic variants of adrenergic receptors and ischemic stroke,and in Alzheimer's disease and mild cognitive impairment.
Best regardes
