Question: What are the genetic changes related to Beare-Stevenson cutis gyrata syndrome ?
Answer: Mutations in the FGFR2 gene cause Beare-Stevenson cutis gyrata syndrome. This gene produces a protein called fibroblast growth factor receptor 2, which plays an important role in signaling a cell to respond to its environment, perhaps by dividing or maturing. A mutation in the FGFR2 gene alters the protein and promotes prolonged signaling, which is thought to interfere with skeletal and skin development. Some individuals with Beare-Stevenson cutis gyrata syndrome do not have identified mutations in the FGFR2 gene. In these cases, the cause of the condition is unknown.
