MTHFD1 encodes the cytoplasmic trifunctional C1-tetrahydrofolate synthase(https://pubmed.ncbi.nlm.nih.gov/22108709/) — three consecutive reactions that interconvert folate one-carbon carriers in the cytoplasm. This central enzyme feeds activated one-carbon units into purine synthesis, thymidylate synthesis, and the...

TCF7L2 (Transcription Factor 7 Like 2) contains the strongest common genetic risk factor for type 2 diabetes(https://pubmed.ncbi.nlm.nih.gov/16415884/) in the human genome. The locus spans roughly 92 kb of chromosome 10 and harbors multiple correlated variants, of which rs7903146 is the primary signal. rs12243326 is...

Deep intronic variant in STAT6 that modulates IL-4/IL-13 signal transduction; the G allele is associated with eosinophilic esophagitis relapse on proton pump inhibitor therapy and with altered eosinophil recruitment in atopic inflammation, likely through effects on STAT6 expression or splicing in Th2-activated tissue

STAT6(https://www.ncbi.nlm.nih.gov/gene/6778) sits at the convergence of the allergic inflammation circuit. When IL-4 or IL-13 binds their shared receptor subunit (IL-4Rα), JAK kinases phosphorylate STAT6, enabling it to dimerize and translocate to the nucleus, where it drives expression of IgE class-switching...

Coding variant in CD33 (Siglec-3) that alters exon 2 splicing in microglia — the T allele promotes exon 2 skipping, producing a short CD33 isoform that lacks the sialic acid-binding IgV domain and enhances microglial phagocytosis of amyloid-beta, reducing Alzheimer's disease risk

CD33 (Siglec-3)(https://pubmed.ncbi.nlm.nih.gov/23946390/) is expressed abundantly on microglia, the brain's resident immune cells and primary clearers of amyloid-beta plaques. In Alzheimer's disease, microglia fail to efficiently engulf and degrade amyloid deposits — and CD33 is a key molecular brake on that...

PPARG (Peroxisome Proliferator-Activated Receptor Gamma()) is one of the most clinically relevant metabolic genes in the human genome. It controls whether stem cells become fat cells, how efficiently adipose tissue stores and releases lipids, and how sensitively peripheral tissues respond to insulin. rs12636454 is...

CYP2C8 is the liver's primary enzyme for metabolizing paclitaxel(https://www.ncbi.nlm.nih.gov/gene/1558) and its newer cousin cabazitaxel. It is also responsible for clearing rosiglitazone and pioglitazone (thiazolidinedione diabetes drugs), repaglinide (a short-acting insulin secretagogue), and the anti-malarial...

CYP7A1(https://www.ncbi.nlm.nih.gov/gene/1581) controls the single most important route by which the body permanently removes cholesterol. Every day, cholesterol 7α-hydroxylase converts a portion of your liver's cholesterol pool into primary bile acids — cholic acid and chenodeoxycholic acid — which are secreted...

Before your body can make the long-chain omega-3 and omega-6 fats that drive anti-inflammatory signaling, membrane integrity, and brain function, it must clear a biochemical bottleneck: the first desaturation step. The enzyme responsible is delta-6 desaturase (D6D)(https://pubmed.ncbi.nlm.nih.gov/19148276/). Without...

Type I collagen is the most abundant protein in bone, accounting for roughly 90% of the organic bone matrix(https://www.ncbi.nlm.nih.gov/books/NBK507817/). The COL1A1 gene encodes the alpha-1 chain, two of which combine with one alpha-2 chain to form the collagen triple helix. Deep within the first intron of COL1A1...
