Discover Your DNA Code
ai-Gene X analyzes your DNA to reveal your unique DNA Code — a 3-character code based on real genetic variants that defines your thinking style, relationship approach, and action pattern.
Unlike personality tests based on self-reported questionnaires, your DNA Code is determined by your actual genetic data — scientifically grounded and uniquely yours.
What is a DNA Code?
Your DNA Code consists of 3 characters, each determined by a specific gene variant (SNP) found in your DNA:
Example DNA Code
AG+
Just like A, T, G, C are the four bases that make up your DNA, your DNA Code uses these same letters to represent who you are — directly from your genome.
A or T — How You Think
Based on rs4680 — COMT gene (Catechol-O-methyltransferase)
The COMT gene controls how fast your brain breaks down dopamine, the neurotransmitter responsible for focus, motivation, and cognitive processing.
A · Analytical
Slow dopamine breakdown → higher prefrontal dopamine levels → strong focus, logical reasoning, systematic planning. You process information methodically and excel at structured problem-solving.
T · Intuitive
Fast dopamine breakdown → more cognitive flexibility → creative thinking, quick adaptation, gut-feeling decisions. You thrive in dynamic environments and see patterns others miss.
G or C — How You Connect
Based on rs53576 — OXTR gene (Oxytocin receptor)
The OXTR gene determines how your brain responds to oxytocin, the "bonding hormone" that influences empathy, trust, and social connection.
G · Independent
Lower oxytocin sensitivity → self-reliant decision making, autonomous leadership, comfortable with solitude. You trust your own judgment and work effectively alone.
C · Compassionate
Higher oxytocin sensitivity → deep empathy, strong social bonds, natural caregiver. You read emotions easily and build meaningful relationships.
+ or − — How You Act
Based on rs1800955 — DRD4 gene (Dopamine receptor D4)
The DRD4 gene influences your brain's novelty-seeking response — how you react to new experiences, challenges, and stimulation.
+ · Drive
Higher novelty seeking → proactive execution, risk-taking, challenge-oriented. You actively pursue goals and thrive under pressure.
− · Calm
Lower novelty seeking → reflective observation, careful analysis, deep thinking. You prefer to fully understand before acting.

DNA Lifestyle Profile
Beyond your DNA Code, ai-Gene X analyzes additional genetic variants to reveal your lifestyle traits — how your body responds to caffeine, alcohol, dairy, and your natural sleep pattern. These are among the most well-established gene-trait associations in human genetics.
Caffeine Metabolism
rs762551 — CYP1A2 (Cytochrome P450 1A2)CYP1A2 is the primary enzyme responsible for metabolizing caffeine in the liver. The rs762551 variant determines how fast your body breaks down caffeine:
- AA genotype → Fast metabolizer — caffeine is cleared quickly, may benefit from pre-exercise caffeine
- AC or CC genotype → Slow metabolizer — caffeine stays in system longer, higher risk of jitteriness and sleep disruption
Cornelis, M.C. et al. (2006). "Coffee, CYP1A2 genotype, and risk of myocardial infarction." JAMA, 295(10), 1135-1141.
Guest, N. et al. (2018). "Caffeine, CYP1A2 genotype, and endurance performance in athletes." Medicine & Science in Sports & Exercise, 50(8), 1570-1578.
Sleep Chronotype
rs1801260 — CLOCK (Circadian Locomotor Output Cycles Kaput)The CLOCK gene is a master regulator of your circadian rhythm — the internal 24-hour clock that governs when you feel sleepy and alert. The rs1801260 variant (3111 T/C) influences your natural sleep-wake preference:
- TT genotype → Evening chronotype (Night Owl) — naturally stays up late and wakes up later
- TC or CC genotype → Morning chronotype (Early Bird) — naturally wakes early and is most productive in morning hours

Mishima, K. et al. (2005). "The 3111T/C polymorphism of hClock is associated with evening preference and delayed sleep timing." Genes, Brain and Behavior, 4(5), 275-279.
Alcohol Metabolism
rs671 (ALDH2) + rs1229984 (ADH1B)Alcohol metabolism involves two key enzymes. ADH1B converts alcohol to acetaldehyde (toxic), then ALDH2 breaks it down to harmless acetate. Variants in these genes dramatically affect how your body handles alcohol:
- rs671 (ALDH2) — GA or AA genotype → Alcohol flush reaction (facial redness, nausea). ~36% of East Asians carry this variant. Significantly increased risk of esophageal cancer with alcohol consumption
- rs1229984 (ADH1B) — CT or TT genotype → Fast alcohol-to-acetaldehyde conversion, leading to faster accumulation of toxic byproducts

Lactose Tolerance
rs4988235 — MCM6 / LCT (Lactase)All humans produce lactase (the enzyme that digests milk sugar) as infants. The rs4988235 variant determines whether your body continues producing lactase into adulthood — a trait called "lactase persistence" that evolved in dairy-farming populations:
- TT genotype → Lactase persistent — can digest dairy throughout life (~95% of Northern Europeans)
- CT genotype → Partially tolerant — moderate dairy is usually fine
- CC genotype → Lactase non-persistent — likely lactose intolerant (~90% of East Asians, ~75% of Africans)

Accessibility & Color Vision
Approximately 8% of men and 0.5% of women worldwide have some form of color vision deficiency (color blindness), most commonly red-green color blindness — which is itself caused by genetic variants on the X chromosome (OPN1LW, OPN1MW genes).
Our DNA Code system is designed to be accessible regardless of color vision:
- Letters first, colors second — A, T, G, C are always displayed as text, so colors serve as visual enhancement, not the sole identifier
- Brightness contrast — Each color has a distinct luminance level, making them distinguishable even in grayscale
- Context labels — "Analytical," "Intuitive," etc. are always shown alongside the letter and color
Fun fact: Color vision deficiency is one of the most well-studied genetic traits — carried on the same DNA that ai-Gene X analyzes to determine your DNA Code.
Privacy & Security
Your raw DNA file is automatically deleted from our server immediately after analysis.
All genotype data is encrypted using military-grade encryption (Fernet/AES) before storage.
Your DNA Code (e.g. AG+) is an abstracted type — it cannot be reverse-engineered to reveal your actual genetic data.
Your genetic data is never sold, shared, or provided to any third party. Period.
Scientific Basis
The 3 SNPs used in DNA Code determination are among the most extensively studied genetic variants in behavioral genetics, with hundreds of peer-reviewed publications spanning decades of research.
rs4680 — COMT (Catechol-O-methyltransferase)
Chromosome 22 · Missense variant · Val158MetWhat does this gene do?
COMT encodes an enzyme that breaks down dopamine in the prefrontal cortex — the brain region responsible for planning, decision-making, and working memory. The rs4680 variant (Val158Met) determines how fast this enzyme works:
- Val/Val (GG) → Fast dopamine clearance → more cognitive flexibility, better under stress, but lower baseline focus
- Met/Met (AA) → Slow dopamine clearance → higher sustained focus and working memory, but more stress-sensitive
- Val/Met (AG) → Intermediate — balanced between both traits
Why does this determine Analytical vs. Intuitive?
Higher prefrontal dopamine (Met carriers) supports systematic, detail-oriented processing — the hallmark of analytical thinking. Lower prefrontal dopamine (Val carriers) enables rapid cognitive switching and creative associations — characteristic of intuitive thinking. This is often called the "Warrior vs. Worrier" model in behavioral genetics.

rs53576 — OXTR (Oxytocin Receptor)
Chromosome 3 · Intron variantWhat does this gene do?
OXTR encodes the receptor for oxytocin, often called the "bonding hormone." Oxytocin plays a critical role in social recognition, trust formation, empathy, and pair bonding. The rs53576 variant affects how sensitive your brain is to oxytocin signaling.
- GG genotype → Lower oxytocin receptor expression → more self-reliant, emotionally resilient, independent decision-making
- AG or AA genotype → Higher oxytocin sensitivity → greater empathy, stronger social attachment, more responsive to emotional cues
Why does this determine Independent vs. Compassionate?
Individuals with the GG genotype have been shown in multiple studies to exhibit less emotional reactivity and greater autonomy in social situations. Those with A alleles demonstrate heightened empathic accuracy and prosocial behavior. This doesn't mean one is "better" — it reflects different evolutionary strategies for navigating social environments.

rs1800955 — DRD4 (Dopamine Receptor D4)
Chromosome 11 · Promoter variant · -521 C/TWhat does this gene do?
DRD4 encodes a dopamine receptor primarily expressed in the prefrontal cortex and limbic system. It modulates the brain's reward response and sensitivity to novelty. The rs1800955 variant (-521 C/T) affects the transcription efficiency of the DRD4 gene.
- T allele carriers (CT or TT) → Reduced DRD4 expression → heightened novelty seeking, risk-taking, and proactive behavior
- CC genotype → Normal DRD4 expression → preference for stability, careful deliberation, reflective approach
Why does this determine Drive vs. Calm?
When DRD4 expression is reduced, the brain requires more stimulation to activate reward pathways, driving individuals to seek new challenges and take action. Higher DRD4 expression provides sufficient baseline reward satisfaction, enabling calm reflection and deeper analysis before acting. This is the neurobiological basis of the novelty-seeking personality trait first described by Cloninger (1987).

How We Interpret Your DNA Code
Your DNA Code is not a diagnosis or a limitation — it's a probabilistic tendency based on well-established gene-behavior associations. Here's how the interpretation works:
- Genotype extraction — We read the specific alleles at each of the 3 SNP positions from your uploaded VCF file
- Axis determination — Each SNP's genotype is mapped to one of two poles based on the published functional effect of that variant
- Code assembly — The three axis results are combined into your 3-character DNA Code
- Career mapping — Each of the 8 possible codes is associated with career fields that align with the combined personality profile, based on occupational psychology research
Important Disclaimer
Personality is influenced by thousands of genes plus environmental factors. Your DNA Code captures a meaningful genetic signal, but it is one piece of a much larger puzzle. It should be used for self-discovery and exploration, not as a definitive personality assessment. Gene-behavior associations represent statistical trends across populations, not deterministic outcomes for individuals.
