Association of COMT and COMT-DRD2 interaction with creative potential

Area of Science:

• Neuroscience
• Genetics
• Psychology

Background:

• Dopamine (DA) transmission genes are implicated in creativity.
• Catechol-O-methyltransferase (COMT) and dopamine D2 receptor (DRD2) genes are key candidates.
• Previous research indicated DRD2's role in creative potential.

Purpose of the Study:

• To investigate the association of COMT gene polymorphisms with creative potential.
• To examine the interaction between COMT and DRD2 genes in relation to creativity.
• To extend previous findings on DRD2 and creative potential.

Main Methods:

• Genotyped 12 single nucleotide polymorphisms (SNPs) in the COMT gene in 543 Chinese college students.
• Assessed creative potential using divergent thinking tests.
• Performed single SNP analysis, haplotype analysis, and gene-gene interaction analysis.

Main Results:

• Nominal associations were found between specific COMT SNPs and haplotype combinations with measures of verbal and figural creativity.
• No findings remained significant after correction for multiple testing.
• Significant four-way interactions between COMT and DRD2 SNPs were identified for verbal fluency and flexibility, and a three-way interaction for figural flexibility.

Conclusions:

• The study provides nominal evidence for COMT gene involvement in creative potential.
• Suggests that dopamine-related genes, including COMT and DRD2, may interact to influence creativity.
• Highlights the complex genetic architecture underlying creative abilities.
