This study aims to learn more about the genetic changes that cause Goltz syndrome, a rare condition that affects the skin, bones, eyes, and other organs. Researchers are collecting blood samples from up to 84 people with the condition and their parents to analyze their DNA. No treatments or interventions are being tested; the goal is simply to better understand the disease's genetic roots.
