Lamin A is a type of protein that plays a crucial role in maintaining the structure and stability of the cell nucleus. It is part of a group of proteins known as lamins, which form a mesh-like layer called the nuclear lamina just beneath the inner membrane of the nucleus. This structure helps organize the genetic material and supports various cellular functions. Mutations in the Lamin A gene can lead to several genetic disorders, collectively known as laminopathies. These conditions can affect various tissues and organs, leading to symptoms such as muscle weakness, heart problems, and premature aging. Understanding Lamin A is important for developing potential treatments for these diseases.
