Each page covers one condition properly: what it actually is and what it feels like, what causes it, how common it really is and in whom, and how it's diagnosed — followed by the specific variants with a replicated link to it, and, where the research supports it, how genetics can change the way a medicine behaves.
Written in two registers so one page serves both readers: plain language first, then a clinical detail section with the precise terminology, effect sizes and diagnostic thresholds. Every claim is sourced from freely-available published research and cited on the page, so you can check us — or hand the page to your doctor. 27 conditions so far, growing continuously, and free to reuse with attribution (CC BY 4.0).

A common DNA variant near the PITX2 gene is the strongest and most consistently replicated genetic risk factor for atrial fibrillation, the most common irregular heart rhythm and a major cause of stroke.
