The 5-HT2A-rs6314 marker is a single nucleotide polymorphism (SNP) in the HTR2A gene, which encodes the 5-HT2A serotonin receptor. This receptor plays a key role in regulating mood, cognition, sleep, appetite, and how the brain responds to serotonin — one of the most important neurotransmitters for mental health and emotional balance.
The rs6314 SNP involves a C to T substitution at a specific point in the gene, leading to a change in the receptor’s structure and function. Because serotonin receptors influence both the central nervous system and peripheral systems (including gut function and cardiovascular health), variations in this gene may affect both mental and physical health outcomes.
Research suggests that different variants of this marker can influence:
Mood regulation and mental health – The 5-HT2A receptor is strongly linked to depression, anxiety, and emotional regulation. Certain genotypes may increase vulnerability to mood disorders.
Response to antidepressants – Variants of rs6314 have been studied in relation to SSRIs (selective serotonin reuptake inhibitors) and other psychiatric medications. Some individuals may respond better or worse depending on their genotype.
Cognitive performance – This receptor affects learning, memory, and executive function. Differences in rs6314 may influence how people process information or adapt under stress.
Sleep quality – The serotonin system helps regulate sleep cycles; changes in receptor function may impact sleep patterns and overall restfulness.
Pain sensitivity – Some studies link this polymorphism to altered pain perception and sensitivity to chronic pain conditions.
TT genotype (variant): May be linked to reduced receptor activity, influencing serotonin signaling. Some research has associated this genotype with altered emotional regulation, higher risk of depression, and differences in drug response.
CT genotype (heterozygous): May show intermediate effects on serotonin receptor function.
CC genotype (common): Often considered the “normal” or reference genotype, associated with typical receptor function.
It’s important to note that having a particular genotype does not guarantee a health condition — it only suggests a potential predisposition. Environmental factors, diet, stress, and lifestyle all play a large role in whether genetic risks become health issues.
If your test shows a variation in 5-HT2A-rs6314, it may be helpful to consider:
Mental health monitoring – Being aware of mood changes, anxiety, or stress resilience.
Medication response – Sharing results with your healthcare provider may guide more personalized treatment strategies, especially for antidepressants.
Lifestyle support – Stress management, regular exercise, balanced diet, and quality sleep can all positively influence serotonin balance.
Nutritional considerations – Adequate intake of tryptophan (found in turkey, eggs, seeds, and nuts) and cofactors like vitamin B6 and magnesium may support serotonin production.
The 5-HT2A-rs6314 marker provides valuable insight into how your serotonin system functions and how your body may respond to stress, mood challenges, and certain medications. Understanding this SNP can help patients and practitioners take a more personalized approach to mental health, wellness, and treatment decisions.

I have been using Healthmatters.io since 2021. I travel all over the world and use different doctors and health facilities. This site has allowed me to consolidate all my various test results over 14 years in one place. And every doctor that I show this to has been impressed. Because with any health professional I talk to, I can pull up historical results in seconds. It is invaluable. Even going back to the same doctor, they usually do not have the historical results from their facility in a graph format. That has been very helpful.
