This article explains the genetic traits behind neuropathic pain and how genetic insight informs a provider-guided management conversation.

IgA nephropathy (Berger's disease) is the most common primary glomerular kidney disease, and genetics shapes both risk and course. This article explains the four-hit model, key risk loci in the HLA region and complement genes CFHR3/CFHR1, TNFSF13, and DEFA, and its health effects.

Age spots (solar lentigines) form where UV meets your pigmentation genetics: MC1R and IRF4 variants decide how readily skin overproduces melanin in the sun. This article explains the genes behind sun spots, the gene-environment link, and evidence-based prevention and management.

About half of alcohol use disorder risk is genetic, driven by variants in metabolism genes ADH1B and ALDH2 and reward genes GABRA2 and DRD2. Learn how the protective ADH1B rs1229984 and ALDH2 rs671 variants work, and why genetics shifts vulnerability without determining outcome.

Alzheimer's risk is shaped by genetics, led by the APOE e4 allele, plus risk-modifying genes like TREM2, CLU, and SORL1 and rare early-onset mutations in APP, PSEN1, and PSEN2. Learn what the research shows, why genes are not destiny, and how pathway-level genetic insight supports brain-health decisions.

The NOS3 gene builds eNOS, the enzyme that makes nitric oxide to keep blood vessels flexible and healthy. Learn how variants like Glu298Asp and -786T>C shift cardiovascular risk, what research shows about endothelial function, and how pathway-level genetic insight informs provider conversations.

IL-23R gene variants shape the IL-23/Th17 immune pathway that drives inflammation. The R381Q variant (rs11209026) is linked to lower autoimmune risk. This article explains what IL-23R does, what the research shows across inflammatory conditions, and how pathway-level genetic insight adds context — never a diagnosis.

NAT2 slow acetylator status — driven by variants like NAT2*5 (rs1801280) and NAT2*6 (rs1799930) — means your liver processes certain aromatic amines more slowly. Research links it to exposure-related risks such as bladder cancer in smokers. Learn what slow acetylator status means and how genetic insight adds pathway-level context.

Oxytocin, the "love hormone," shapes empathy, trust, and social bonding — and genes like OXTR (variant rs53576), CD38, and AVPR1A influence how your brain produces and responds to it. This article explains the biology of connection, what the research really shows, and how experience shapes genetic expression.

Genes like GDF5, COL1A1, and COMT shape disc strength and how intensely you feel pain, which helps explain why back pain often runs in families. This article covers the genetic pathways behind spinal health, what DNA can and cannot predict, and the evidence-based habits that protect your back.

PEMT gene variants such as rs7946 lower your body's ability to make choline internally, raising the risk of deficiency when dietary intake is low — especially in postmenopausal women.
