Oliver syndrome


Title

Summary Summary


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

Orpha Number: 2920

Definition
Oliver syndrome is a very rare syndrome characterized by intellectual deficit, postaxial polydactyly, and epilepsy.

Epidemiology
To date, seven individuals in three families have been reported.

Clinical description
Facial features are not characteristic except for a prominent jaw. Concordant features in all subjects are postaxial polydactyly, which in four individuals affect also the feet, and intellectual deficit, which is usually severe, with absent or indistinct speech. Seizures are common with onset in the first months of life or in early childhood. Cutaneous syndactyly, camptodactyly and clinodactyly of fingers and brachydactyly and syndactyly of the toes have been recorded.

Genetic counseling
The condition is probably hereditary, and transmitted as an autosomal recessive trait.

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.

In-Depth Information

  • The Monarch Initiative brings together data about this condition from humans and other species to help physicians and biomedical researchers. Monarch’s tools are designed to make it easier to compare the signs and symptoms (phenotypes) of different diseases and discover common features. This initiative is a collaboration between several academic institutions across the world and is funded by the National Institutes of Health. Visit the website to explore the biology of this condition.
  • Online Mendelian Inheritance in Man (OMIM) is a catalog of human genes and genetic disorders. Each entry has a summary of related medical articles. It is meant for health care professionals and researchers. OMIM is maintained by Johns Hopkins University School of Medicine.
