LAMP2 gene

The LAMP2 gene produces a protein called Lysosome-Associated Membrane Protein 2, which is essential for the function of lysosomes—cell parts responsible for breaking down waste and recycling materials. Proper LAMP2 function helps cells manage damaged components and maintain overall health. Mutations or defects in the LAMP2 gene can impair lysosome activity, leading to a rare disorder called Danon disease, characterized by muscle weakness, heart problems, and mental decline. In summary, LAMP2 is vital for cellular cleanup and health, supporting the body's ability to process and eliminate waste inside cells.
