Stress-response tendency

Achievement Potential

The "worrier-warrior" idea comes from research on the COMT gene, which influences dopamine breakdown in the prefrontal cortex.

The Val and Met variants in COMT have been associated with subtle differences in cognitive style under stress, with no single profile being globally better or worse.

This result reflects research-level variation in dopamine biology and is not a personality test or a performance prediction.

Stress, sleep, mood, training, task type, and overall health all strongly affect how this biology actually shows up in behavior.

Genes analyzed

Gene summaries include genomic locations and associated markers. A detected genotype does not by itself indicate a health condition.

Understanding the data

SNP: A specific genetic marker relevant to this trait.
Genotype: The DNA letters reported at a marker location.
Variant allele: The alternative DNA sequence at the SNP site.
Variant allele frequency: The reported percentage of the reference population carrying this variant.
Variant found: Whether the variant was detected in your DNA file.

1 of 1 genes have detected genotypes.

COMT

Catechol-O-methyltransferase catalyzes the transfer of a methyl group from S-adenosylmethionine to catecholamines, including the neurotransmitters dopamine, epinephrine, and norepinephrine. This O-methylation results in one of the major degradative pathways of the catecholamine transmitters. In addition to its role in the metabolism of endogenous substances, COMT is important in the metabolism of catechol drugs used in the treatment of hypertension, asthma, and Parkinson disease. COMT is found in two forms in tissues, a soluble form (S-COMT) and a membrane-bound form (MB-COMT). The differences between S-COMT and MB-COMT reside within the N-termini. Several transcript variants are formed through the use of alternative translation initiation sites and promoters. [provided by RefSeq, Sep 2008]

DNA Genics reports genotypes based on the 'positive' strand of the human genome reference sequence (build 37/HG19). Other companies may use the opposite strand, so genotypes may need conversion for comparison.
