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.

| SzGene | Meta-analysis Overview |
Due to the dopamine hypothesis of schizophrenia the SNP has been investigated for link to schizophrenia, and it may be slightly associated with this disorder.[1]
The SNP has been investigated with respect to novelty seeking, — a personality trait that may be measured with the Temperament and Character Inventory.[2][3] A 2008 meta-analysis indicates a possible association between novelty seeking and C-521T though rather small.[4]
