Skeletal Disorders

Background: There are 461 conditions that affect the bones (skeletal disorders). Many of these are not well understood and do not have any specific treatments. Researchers want to collect more data about these conditions. Objective: To gain more information about the causes of skeletal disorders and how they progress over time. Eligibility: People ages 2 months or older with known or suspected skeletal disorders or history of pregnancy affected by skeletal findings. Also, healthy family members of affected enrolled participants. Design: Participants can take part in the study either remotely or in person. Those who take part remotely may send in medical records, blood samples, photographs, and other materials. Participants medical records will be reviewed. They may give blood and/or urine samples. They will give blood, saliva, or tissue samples for genetic tests. They may have genetic counseling. Participants ages 2 years and older may have different kinds of imaging scans, such as x-rays. For these scans, they may have to lie still while machines take pictures of their bones. Participants with skeletal disorders who come to the clinic will be examined. They may be asked
