LZTR1 is a gene that provides instructions for making a protein involved in regulating cell growth and division. This protein plays a crucial role in various cellular processes, including the response to stress and the maintenance of cellular functions. Mutations in the LZTR1 gene can lead to disruptions in these processes. Research has shown that alterations in LZTR1 are associated with certain types of cancer, particularly schwannomatosis, a condition characterized by the growth of tumors on nerves. Understanding the function of LZTR1 can help scientists develop targeted therapies for diseases linked to its dysfunction.
