ALK (anaplastic lymphoma kinase) is a protein that plays a role in normal cell development. In healthy adult lung tissue, the ALK gene is essentially switched off. In approximately 3–7% of non-small cell lung cancers, a chromosomal rearrangement — a structural change in which a segment of DNA breaks and fuses to a different gene …

ALK (anaplastic lymphoma kinase) is a gene that normally plays a role in the development of nerve cells. In healthy adult tissue, the ALK gene is essentially switched off, producing little to no protein. In some cancers, however, a structural change in the DNA causes the ALK gene to fuse with another gene — a …

ALK-negative anaplastic large cell lymphoma (ALCL) is a type of cancer that starts in T cells, which are specialized white blood cells that help the body fight infections. Because it begins in immune system cells, it is classified as a non-Hodgkin lymphoma (NHL). This disease can start in many different parts of the body. Common …

ALK-positive anaplastic large cell lymphoma (ALCL) is a type of cancer that starts in T cells, which are specialized white blood cells that normally help the body fight infections. Because it develops from immune cells, it is classified as a non-Hodgkin lymphoma (NHL). This disease most often involves lymph nodes, but it can also appear …
