See how a change connected to a specific gene can affect biological function and contribute to a genetic disorder.
The Disease-Linked DNA Explorer connects an inherited disorder to the gene involved, the kind of genetic change, the biological function affected, and how that contributes to the condition.
It turns an abstract idea ("a change in a gene") into a clear, disease-specific story, without diagnosing anyone or predicting any individual outcome.
This is education, not a diagnosis
How a change connected to the CFTR gene can affect salt and water movement and contribute to cystic fibrosis.
Step 1 of 5
The CFTR gene carries the instructions for a channel protein on the surface of many cells that helps move chloride (a component of salt) in and out.
What this tool shows
The tool shows a disease-specific path from a gene, through a genetic change and a functional effect, to how a condition can arise.
What the results mean
Each step is general educational biology for that condition, for example, one gene’s role and the effect of a change.
What the results do not mean
It does not test DNA, interpret variants, diagnose anyone, or predict any individual’s health.
Educational tools, not medical advice
