Title

Other Names:

Hennekam Beemer syndrome; Skin mastocytosis hearing loss microcephaly mild dysmorphic features and severe mental retardation

Categories:

Congenital and Genetic Diseases

This disease is grouped under:

Mastocytosis

Summary Summary

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

Orpha Number: 2135

Definition

Hennekam-Beemer syndrome is characterized by the association of skin mastocytosis (appearing as diffuse pigmentation), short stature, microcephaly, conductive hearing loss, and dysmorphic features. It has been described in only two (female) cases: one with normal mental development born to consanguineous parents and the other with severe psychomotor retardation born to unrelated parents. The mode of inheritance is most likely autosomal recessive.

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.
