Campomelic dysplasia is a rare genetic disorder that affects the development of the skeleton, reproductive system, and face. Symptoms of Campomelic dysplasia may include bowing of the legs, dislocated hips, small lungs and chest, and external genitalia that do not look clearly male or clearly female (ambiguous genitalia). In addition, infants with Campomelic dysplasia have distinctive facial features including a small chin with cleft palate, prominent eyes, flat face, and a large head. Campomelic dysplasia usually results from a new genetic change (DNA variant) in or the near the SOX9 gene. Diagnosis is based on physical findings and x-ray (radiograph) findings and may be confirmed by genetic testing.

About Campomelic dysplasia
Many rare diseases have limited information. Currently GARD aims to provide the following information for this disease:
Population Estimate:This section is currently indevelopment.
Symptoms:May start to appear during Pregnancy and as a Newborn.
Cause:This disease is caused by a change in the genetic material (DNA).
Organizations:Patient organizations are available to help find a specialist, or advocacy and support for this specific disease.
Symptoms of this disease may start to appear during Pregnancy and as a Newborn.
The age symptoms may begin to appear differs between diseases. Symptoms may begin in a single age range, or during several age ranges. The symptoms from some diseases may begin at any age. Knowing when symptoms began to appear can help medical providers find the correct diagnosis.

Genetic Disease
Campomelic dysplasia is a genetic disease, which means that it is caused by one or more genes not working correctly.
Disease-causing variants, or differences, in the following gene(s) are known to cause this disease: SOX9
What Is a Gene?
Understanding what genes are and how changes in genes may affect the body can help you on the journey to diagnosis and treatment of a genetic disease.
Genes are part of our DNA, the basic genetic material found in each of our body's cells. Cells are the building blocks of all living things and specialized cells form our body's organs and tissues. DNA is found in the nucleus of a cell and, in humans, is packaged into 23 pairs of chromosomes with the help of special proteins.
Each gene performs a different job in our cells. Some genes serve as the instructions to make proteins. Proteins are needed for the structure, function, and regulation of the body's cells, tissues, and organs. Some genes can turn other genes on or off. Others make RNA molecules that are involved in chemical reactions in the body.
Patient organizations can help patients and families connect. They build public awareness of the disease and are a driving force behind research to improve patients' lives. They may offer online and in-person resources to help people live well with their disease. Many collaborate with medical experts and researchers.
Services of patient organizations differ, but may include:
Ways to connect to others and share personal stories
Easy-to-read information
Up-to-date treatment and research information
Patient registries
Lists of specialists or specialty centers
Financial aid and travel resources

Clinical studies are part of clinical research and at the heart of all medical advances, including rare diseases. Participating in research helps researchers ultimately uncover better ways to treat, prevent, diagnose, and understand human diseases.
What Are Clinical Studies?
Clinical studies are medical research involving people as participants. There are two main types of clinical studies:
Clinical trials determine if a new test or treatment for a disease is effective and safe by comparing groups receiving different tests/treatments.
Observational studies involve recording changes over time among a specific group of people in their natural settings.
People participate in clinical trials for a variety of reasons. Participants with a disease may participate to help others, but also to possibly receive the newest treatment and additional care from clinical study staff. Healthy volunteers may also participate to help others and to contribute to moving science forward.
How Do You Find the Right Clinical Study?
To find the right clinical study we recommend you:
Use ClincalTrials.gov button below to search for studies by disease, terms, or country.
Consult doctors, other trusted medical professionals, and patient organizations.
Enroll in databases to allow researchers from participating institutions to find you.
What if There Are No Available Clinical Studies?
ResearchMatch helps connect people interested in research studies with researchers from top medical centers across the United States. Anyone from the U.S. can register with this free program funded by NIH. Researchers from participating institutions use the database to search for and invite patients or healthy volunteers who meet their study criteria to participate.
