Your liver converts nicotine to cotinine in minutes. The enzyme doing this work — CYP2A6 — is encoded by one of the most polymorphic drug-metabolism genes in the human genome. The CYP2A62 allele(https://www.ncbi.nlm.nih.gov/snp/rs1801272) swaps a single amino acid at position 160 of the protein, replacing leucine...

The ACTN3 gene encodes alpha-actinin-3(), a structural protein found exclusively in fast-twitch (type II) muscle fibers. It is arguably the most replicated finding in exercise genetics. A single C-to-T change at position 577 converts an arginine codon to a premature stop codon, completely abolishing protein...

Intronic variant tagging the HNF4A P2 promoter risk haplotype; the T allele impairs glucose-stimulated insulin secretion — particularly in non-obese individuals — by reducing beta-cell-specific HNF4A isoform expression, and confers elevated diabetes risk with a notably strong effect under metabolic stress (OR 2.44 for post-transplant diabetes)

Your pancreatic beta cells carry a dedicated gene control switch — the P2 promoter of HNF4A(https://pubmed.ncbi.nlm.nih.gov/15047633/) — that coordinates dozens of genes required for glucose-stimulated insulin secretion. rs1884614 is a common intronic variant located within the P2 haplotype block on chromosome 20....

Your HDL cholesterol is not just a passive bystander in cardiovascular health — it is actively dismantled and rebuilt by a family of enzymes, and endothelial lipase (EL)(https://www.ncbi.nlm.nih.gov/gene/9388) is one of the primary drivers of HDL catabolism. Unlike lipoprotein lipase (which targets triglyceride-rich...

Paraoxonase-1 (PON1) is one of the most important enzymes you've likely never heard of. It travels attached to HDL particles(https://pubmed.ncbi.nlm.nih.gov/18349088/) in the bloodstream, where its primary job is to hydrolyze oxidized phospholipids(https://pubmed.ncbi.nlm.nih.gov/22685667/) before they can damage...

Age-related macular degeneration (AMD) is the leading cause of irreversible vision loss in people over 65, and dysregulation of the complement immune system is its best-understood molecular driver. rs2274700 is a synonymous variant in exon 10 of CFH (Complement Factor H) — it does not change the amino acid sequence...

ABCA1| ATP-Binding Cassette Transporter A1 — a cell-membrane pump that loads cholesterol and phospholipids onto lipid-poor apolipoprotein A-I, forming nascent HDL particles is the primary gatekeeper of reverse cholesterol transport(). Without ABCA1, cells cannot shed excess cholesterol and HDL formation collapses....

Alpha-1 antitrypsin (AAT) is the body's primary defense against neutrophil elastase, a powerful enzyme(https://medlineplus.gov/genetics/gene/serpina1/) that can destroy lung tissue if left unchecked. The Z allele (Glu342Lys) is the most common genetic variant causing severe AAT deficiency, affecting approximately 1...

The FAAH gene encodes fatty acid amide hydrolase(https://pubmed.ncbi.nlm.nih.gov/12060782/), which binds to the same receptors as THC from cannabis. The rs324420 variant changes a single amino acid at position 129 from proline to threonine, making the enzyme more vulnerable to breakdown. Carriers of the A allele...
