X-Linked Diseases

Video Source: Children's National Hospital

Females with X-linked conditions have inherited the defective gene from either their mother or father, or in rare cases, have spontaneously developed a mutated gene on one of their X chromosomes. They themselves have a 50% chance of passing the gene down to any children they have. While females have two X chromosomes and have traditionally been considered "carriers," many females experience symptoms of their disease due to a process called X inactivation.

 

Below is our list of X-linked diseases. Please click on the lightning bolt icon to learn more about each condition. Unfortunately, not all sources below go into detail about symptoms experienced by female "carriers," as research on this topic is sparse.
