When a wound does not heal properly, it leaves a scar. Similarly, mutations—which are permanent changes to genetic code—are often the result of damaged DNA that has not been properly repaired. Mutations can impede the function of genes and lead to disease and aging, but they are

Researchers at Weill Cornell Medicine have uncovered how a key Parkinson's protein called LRRK2 shifts between inactive and active forms, revealing the structural changes that enable certain mutations to push the protein into an overactive state. Mutations that cause LRRK2 to bec

Cancer cells rely on powerful genetic switches to keep growth genes running at full speed, but that intense activity can damage their own DNA. The resulting breaks are repeatedly repaired, sometimes with small mistakes that allow new mutations to accumulate. Researchers believe t

Inherited bone marrow failure syndrome, or IBMFS, describes a group of disorders in which inherited genetic abnormalities impair the bone marrow's ability to produce sufficient healthy blood cells. Patients with these disorders are also at increased risk of developing myelodyspla
