There is no single gene for a degree. Educational attainment is polygenic, shaped by thousands of variants plus environment. This article explains how genes like COMT and BDNF influence focus and memory, why polygenic scores explain only part of the picture, and what genetic insight can and cannot tell you.

Ayurvedic constitution, or Prakriti, groups people by traits in metabolism, thermoregulation, digestion, and temperament. Ayurgenomics research links these types to genes such as EGLN1 and CYP2C19. Learn which attributes are mapped, what the evidence shows, and how to interpret constitutional biomarkers.

PTSD is roughly 30% to 40% heritable, and named variants in FKBP5, ADCYAP1R1, BDNF, and COMT shape how the stress and fear-memory systems respond to trauma. This article explains what these genes do, how gene-by-environment interaction works, and why genetic insight is context, not a diagnosis.

Genes like MAOA and COMT Val158Met shape how quickly your brain builds, uses, and clears the dopamine and serotonin behind emotional reactivity. This article explains what the "warrior gene" research really shows, why anger is polygenic, and how pathway-level genetic insight puts your temperament in context.

Extraversion and introversion are roughly 40 to 60 percent heritable, shaped by dopamine and serotonin genes including DRD4, DRD2, COMT (rs4680), and SLC6A4. This article explains how these variants influence reward sensitivity and social temperament — and why genetics sets tendencies, not a fixed personality.

Genetics explains roughly 40 to 50 percent of depression risk through variants in COMT (rs4680), BDNF Val66Met, and MTHFR C677T. This article explains how these genes shape neurotransmitter and methylation pathways, why environment still decides the outcome, and how pathway-level genetic insight informs a provider conversation.

Suicidal thoughts arise from biology, life circumstances, and mental health together, with heritability estimated at 30 to 50 percent. This article explains the genes studied in stress and mood regulation — SLC6A4, BDNF, and COMT — why genetics is not destiny, and where to find immediate help. If you are in crisis, call or text 988.

Trichotillomania, a hair-pulling disorder affecting 1% to 2% of people, runs in families. This article explains how genes such as SLITRK1 and SAPAP3 (DLGAP3) shape the compulsive urge, the role of serotonin and dopamine circuits, and why genetics is context for professional care rather than a diagnosis or treatment plan.

COMT rs4680 (Val158Met) shapes how quickly the brain clears dopamine from the prefrontal cortex, influencing stress resilience and cognition. Learn what the 'warrior versus worrier' trade-off means, what research shows, and how pathway-level insight from PlexusDx puts this variant in context.

Creativity is polygenic, not a single gene. Variants in COMT, DRD2, and BDNF shape dopamine processing, novelty seeking, and neuroplasticity, tilting how you generate and refine ideas. This article explains the science and the evidence-based habits — sleep, exercise, novel learning — that enhance creativity across any genetic background.

GSK3B codes for an enzyme that sits at the crossroads of insulin signaling, mood regulation, and cellular stress. This article explains what GSK3B variants like rs334558 do, what the research shows, and how pathway-level genetic insight puts the gene in context — a guide, not a diagnosis.

The DRD2 and ANKK1 variant rs1800497 (Taq1A) influences dopamine D2 receptor density, reward sensitivity, and mood. This article explains what the variant does, what research links it to addictive behaviors and mood, and what the Precision Peptide Genetic Test reveals about your dopamine and reward pathways.

The MAOB gene encodes monoamine oxidase B, an enzyme that clears dopamine and generates oxidative byproducts. Variants like rs1799836 have been studied in Parkinson's disease, depression, chronic fatigue, and smoking behavior. This article explains the biology, related genes MAOA and COMT, and what pathway-level genetic insight reveals.

Processing speed — how fast the brain interprets and responds to information — is polygenic, shaped by COMT (rs4680), BDNF Val66Met, CADM2, and myelination genes.
