Definition
Intellectual disability-polydactyly-uncombable hair syndrome is a multiple congenital anomalies/dysmorphic syndrome characterized by intellectual disability, postaxial polydactyly, phalangeal hypoplasia, 2-3 toe syndactyly, uncombable hair and facial dysmorphism (including frontal bossing, hypotelorism, narrow palpebral fissures, nasal bridge and lips, prominent nasal root, large abnormal ears with prominent antihelix, poorly folded helix, underdeveloped lobule and antitragus, and micrognathia evolving into prognatism). Cryptorchidism, conductive hearing loss and progressive thoracic kyphosis were also reported.

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.
