The alcohol flush reaction is caused by an ALDH2 variant carried by hundreds of millions of people. It's more than a red face — it's linked to cancer risk.
Alpha-1 antitrypsin deficiency is frequently misdiagnosed as ordinary COPD or asthma for years. Knowing your SERPINA1 status changes prevention and treatment.
CYP2C19 and CYP2D6 shape how your body handles many antidepressants. Genetics won't pick the drug for you, but it can explain side effects and dosing.
A 32-base-pair deletion in CCR5 blocks the doorway most HIV uses to enter cells. It's the basis of the only confirmed HIV cures — and a cautionary gene-editing tale.
Your natural sleep timing is partly heritable, shaped by clock genes like PER2, PER3 and CLOCK. A rare variant even causes lifelong extreme early rising.
Clopidogrel needs CYP2C19 to activate. Poor metabolizers get little benefit — an FDA boxed-warning issue that genetic testing can flag before a stent fails.
A DPYD variant can make routine fluoropyrimidine chemotherapy fatal. Regulators now recommend testing before treatment — here's why it matters and who should ask.
Eye color isn't a single dominant-recessive gene. OCA2 and HERC2 lead a polygenic system that makes inheritance far more interesting than the textbook version.
Factor V Leiden is the most common inherited clotting disorder, carried by around 1 in 20 people of European descent. Here's what it means for surgery, pregnancy, and travel.
FH affects roughly 1 in 250 people and is dramatically underdiagnosed. A genetic answer can reshape how aggressively your cholesterol is treated — decades earlier.
Hemochromatosis from HFE C282Y variants is one of the most common inherited disorders in people of European descent — and one of the most treatable. Here's what your genome can tell you.
Whether you can digest lactose as an adult comes down to a single regulatory variant near the LCT gene — and it's one of the clearest examples of recent human evolution.
Long QT syndrome affects roughly 1 in 2,000 people and can cause fainting or sudden cardiac death — often in young, otherwise-healthy individuals. Genetics can flag it.
The AR gene on the X chromosome matters, but hair loss is highly polygenic. Here's what genome data can and can't tell you about going bald.
The UK, US and others are piloting whole genome sequencing at birth to screen for hundreds of treatable conditions. Here's where the science stands in 2026.
LRRK2 and GBA are the two most important genes in Parkinson's risk. Here's what carrying a variant does — and doesn't — mean, and why penetrance matters.
A single SLCO1B1 variant markedly raises statin exposure and the risk of muscle side effects. CPIC has published dosing guidance based on it.
TCF7L2 is the strongest common genetic risk factor for type 2 diabetes. But it's one of the most modifiable — lifestyle changes work even harder for carriers.
VKORC1 and CYP2C9 together explain a large share of the huge person-to-person variation in warfarin dose. Genotype-guided dosing is FDA-labeled.
Exome sequencing reads ~1-2% of your genome; whole genome reads it all. Here's exactly what each catches, what each misses, and when the price gap is worth it.
