Deafness Onychodystrophy Osteodystrophy and Mental Retardation Syndrome
Type of disease: Rare conditions
Deafness onychodystrophy osteodystrophy and mental retardation (DOOR) syndrome is a rare genetic disorder that is usually recognized shortly after birth. The term DOOR is an acronym with each letter representing a common feature in affected individuals: (D)eafness due to a defect of the inner ear or auditory nerve; (O)nychodystrophy or malformation of the nails; (O)steodystrophy, meaning malformation of certain bones; and mild to profound mental (R)etardation, which is now referred to as intellectual disability. In some cases, individuals may also experience seizures. This condition is inherited in an autosomal recessive fashion; the exact genetic cause is unknown.
