Learn how ILD affects breathing, why symptoms build gradually, how specialists monitor and manage it, and where inherited variants like MUC5B rs35705950 and TERT add pathway-level context.

Raynaud's phenomenon is highly heritable, and a 2023 genome-wide study named ADRA2A and IRX1 as key risk genes governing blood-vessel constriction. Learn how these variants shape cold-triggered symptoms and how pathway-level genetics can inform a more precise conversation with your provider.

GDF5, COMT, and collagen genes like COL2A1 help set joint pain and osteoarthritis risk — twin studies tie 40 to 65 percent of that risk to heredity. This article explains the cartilage, inflammation, and pain-signaling pathways behind sore joints and how pathway-level genetic insight fits in.

Lichen planus is a T-cell-mediated inflammatory condition tied to immune genes in the HLA region, including HLA-DRB1 and HLA-DQB1. This article explains the immune mechanism, named genetic associations, the hepatitis C link, and where pathway-level genetic insight fits into provider-led care.

Scoliosis affects 2 to 3 percent of people, and genetics plays a real role — with LBX1 the most replicated gene linked to adolescent idiopathic scoliosis. This article explains the polygenic factors behind spinal curvature, connective-tissue and bone-density genes like COL1A1 and VDR, and what genetic insight adds.

Your eGFR gauges kidney filtration, and genetics helps shape it. Variants near UMOD (rs12917707), plus SHROOM3, GATM, and APOL1, are linked to kidney function in research. Learn what the science shows about inherited kidney tendencies and how the Precision Peptide Genetic Test maps related pathways.

Contact dermatitis susceptibility is shaped by genes like FLG, which builds the skin barrier, and GSTM1 and GSTT1, which process chemicals. This article explains the genetics behind skin rash, what the research shows, and what the Precision Peptide Genetic Test reveals about your skin-barrier and detox pathways.

Genetic variation in detox enzymes helps explain why people react differently to pesticides. PON1 variants rs662 and rs854560, plus CYP450, GSTM1, and GSTT1 genes, shape how efficiently you clear organophosphates. Learn how genetics modifies pesticide sensitivity and why reducing exposure protects everyone.

Pyroglutamic acid (5-oxoproline) is a checkpoint in the gamma-glutamyl cycle that builds glutathione, your cells' master antioxidant. The OPLAH and GSS genes regulate this loop. Learn how pyroglutamic acid reflects oxidative-stress balance and what pathway-level genetics can reveal.

Platelet function is shaped by genes like ITGB3, GP1BA, and ITGA2 that build the receptors platelets use to clot. This article explains how platelets work, what the ITGB3 PlA1/A2 polymorphism means, and how pathway-level genetic insight adds context to a conversation with your provider.

The ACE gene shapes blood pressure, heart structure, and endurance through the renin-angiotensin system. This guide explains the ACE insertion/deletion (I/D) polymorphism, why the D allele links to higher ACE activity and blood pressure, and how the I allele connects to endurance performance in the research.

Cerebral small vessel disease quietly damages the brain’s smallest vessels and drives vascular cognitive decline. Learn how genes like NOTCH3 and MTHFR shape risk, what research shows about homocysteine and blood pressure, and how pathway-level genetic insight supports informed conversations with your provider.

Gout is driven more by genetics than diet. Variants in urate-transporter genes—ABCG2 (rs2231142), SLC2A9/GLUT9, and SLC22A12/URAT1—determine how efficiently your body clears uric acid.
