Genetic changes to human skin contribute to a wide variety of conditions and diseases that affect over 20% of the population. However, the genes and molecules that are responsible for human skin development and disease are not fully understood, preventing the development of treatment options. This proposal seeks to better understand one disease in particular, linear morphea, a form of Sclerederma that can affect the skin, muscle, and bone. This study will recruit subjects to collect and use skin tissue for the purpose of identifying the genetic causes of linear morphea.
