Cousin syndrome


Title


Other Names:
Craniofacial dysmorphism, hypoplasia of scapula and pelvis and short stature; Pelviscapular dysplasia
Categories:
Congenital and Genetic Diseases; Musculoskeletal Diseases

Summary Summary


Listen
Cousin syndrome is a rare syndrome characterized mainly by short stature at birth, unusual facial appearance and skeletal abnormalities involving the shoulder blades and hips. Intelligence may vary from normal to moderately delayed.[1] Mutations in the TBX15 gene inherited in an autosomal recessive pattern have been suggested as the cause of this condition.[2]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
