DRD3

A gene on chromosome 3q13.3 that encodes G protein-coupled dopamine receptor D3, which inhibits adenylyl cyclase. D3 dopamine  receptor localises to the limbic areas of the brain, which are associated with cognitive, emotional, and endocrine functions.
Molecular pathology Genetic variants of DRD3 cause essential tremor hereditary type 1 .

A total of 160 sporadic TS patients (including 101 TS patients) involved in pedigree studies and 59 unrelated cases underwent DRD3 SNP rs6280 analysis.

Transmission disequilibrium test analysis revealed no transmission disequilibrium in the DRD3 rs6280 SNP among TS nuclear pedigrees, indicating that this locus is not associated with TS ( P = 1; [Table 5]).
Dopamine D3 receptor is mainly located in the region of the brain associated with cognition and affection, and the DRD3 receptor is highly expressed in the mesolimbic dopamine system including the extended amygdala.

The work of Amigo, Caselles, and Mico (2013) studies the temporary change of the GFP in relation with the regulating gene DRD3 (like another biological substratum of personality) as a consequence of a suggestion technique, being observed that as much the GFP as the DRD3 respond to a dynamic pattern similar to the one reproduced by the response model.
