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. 385 conditions so far, growing continuously, and free to reuse with attribution (CC BY 4.0).

Erythematosquamous Dermatosis, as genome-wide studies have reported it: 3 positions from 1 study, the largest recording 38,469 cases and 568,738 controls (African American or Afro-Caribbean ancestry, Hispanic or Latin American ancestry, East Asian ancestry, European ancestry). Built from the GWAS Catalog's records and rebuilt when a new position is reported; the figures are the studies'.
Read more → DermatologicDermatophytosis, as genome-wide studies have reported it: 7 positions from 1 study, the largest recording 256,822 European, African, Hispanic or Latin American and Asian ancestry cases, 1,372,501 European, African, Hispanic or Latin American and Asian ancestry controls. Every figure comes from the studies themselves, gathered by code from the GWAS Catalog and updated as the records grow.

Read more → DermatologicRaised scars that outgrow the original wound, mapped by a 2025 multi-ancestry study of nearly 1.6 million people — which found the genetic risk itself differs sharply by ancestry.
Read more → DermatologicAn occupational disease: a severe hypersensitivity reaction some solvent-exposed workers develop to trichloroethylene, an industrial degreasing agent. A study of Chinese factory workers found a genetic risk score at MICA explaining over 20% of the disease's variance — large for this catalogue — with real relevance to pre-employment genetic screening for this specific job risk.
Read more → DermatologicHow two pigmentation variants (IRF4 rs12203592 and SLC45A2 rs16891982) relate to freckling and sun sensitivity, what they do and do not say about melanoma and skin cancer risk, and why early detection matters most.
Read more → DermatologicMale pattern baldness is strongly heritable and linked to a variant in the androgen receptor gene on the X chromosome. That partly explains the 'blame your mother's father' folklore, but dozens of other genes also matter.
Read more →One diagnosed condition or measurable trait covered properly: what it actually is, what causes it, how common it is, how it is diagnosed, and the specific variants with a replicated link to it — every claim sourced from published research.
No. Every page here is informational, not a diagnosis. A result should be discussed with a doctor or a licensed genetic counselor, never acted on alone.
Because they are not disorders. Height, ABO blood group and a handful of others describe a measurable characteristic with nothing to diagnose — "Trait" says so plainly instead of implying a disease that is not one.
Only after a replicated association in published research, verified against the primary study rather than a gene name or a marketing claim — the same discipline the variant pages themselves follow.
