which gene does progeria affect
The gene responsible for HGPS is called LMNA (pronounced âlamin-aâ). Within this gene there is a change in one piece of DNA that is responsible for Progeria. This type of gene change is called a point mutation. The LMNA gene makes a protein called Lamin A, which is an important protein for most cells of our bodies. Lamin A is found in the cell nucleus (the part of each cell that contains the DNA), and helps maintain the shape and function of the cell. The point mutation compromises that cell integrity, causing Progeria.
