Each condition is different and has a unique set of symptoms.
To date, there have been hundreds of X-linked conditions identified – many of them are ultra-rare, only affecting a few people around the world. While all X-linked conditions are caused by mutations on the X chromosome, each condition is different and has a unique set of symptoms. For some of these conditions, females are impacted by symptoms more frequently and more severely, and for others, females are rarely impacted by symptoms. Whether or not a female with an X-linked condition has symptoms is determined by multiple factors, including underlying disease mechanisms and X-inactivation, which is poorly understood and unpredictable. To create more awareness, we built a Master List of identified X-linked conditions below.
Despite this, these conditions all have one thing in common—they are X-linked. If you’re unsure and curious what this means, there is more information on the How It Works page.
