Craniofacial dysostosis with diaphyseal hyperplasia

Title

Other Names:

Dysostosis Stanescu type; Stanescu osteosclerosis

Categories:

Congenital and Genetic Diseases; Musculoskeletal Diseases

Summary Summary

The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.

Orpha Number: 1798

Definition

Stanescu type dysostosis is a rare form of osteosclerosis.

Epidemiology

So far it has been described in around 30 patients from three families.

Clinical description

It is characterized by craniofacial dysostosis with a small cranium and thin skull bone, depressions over the frontoparietal and occipitoparietal sutures, marked hypoplasia of mandible, exophthalmos, cortical sclerosis of the long bones and normal intelligence. The long bones are short and bent, and thickening of bone cortex occurs during the pubertal and post-pubertal periods and increases with age.

Genetic counseling

The syndrome is inherited in an autosomal dominant manner.

Symptoms Symptoms

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.
