In genetics, rs1800955 (also written as C-521T and -521C/T) is a single nucleotide polymorphism (SNP). It is located in the promoter region of the DRD4 gene. This gene codes for the dopamine receptor D4.
The SNP has been investigated with respect to novelty seeking, — a personality trait that may be measured with the Temperament and Character Inventory. A 2008 meta-analysis indicates a possible association between novelty seeking and C-521T though rather small.
