Summary Summary

Blepharophimosis intellectual disability syndromes refers to a group of syndromes, including Ohdo syndrome and Say Barber Biesecker Young-Simpson syndrome, that are characterized by narrow eye openings (blepharophimosis), drooping of the upper eye lids (ptosis) and intellectual disability. Dr. Ohdo published an article in 1986 describing the first three cases of this syndrome (in a brother, sister, and cousin).^[1]^[2] Since that time many other case reports describing people with similar (yet variable) features have been reported. The syndromes usually occur sporadically. In most cases the underlying cause can not be determined.

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.
