    General Discussion
    Hypomelanosis of Ito (HI) is a rare disorder that is distinguished by a lack of skin color (hypopigmentation) affecting many areas of the body. The defect in skin color is likely to appear as streaks, patches, or whorls. It is often associated with other symptoms such as intellectual and developmental retardation, seizures (neurological anomalies), ocular, skeletal and dental problems and/or a small head. The diagnosis is sometimes difficult due to the number and variety of other conditions that may be present and confuse the situation. Most cases of HI are not the result of an inherited defect, although some cases are inherited as an autosomal dominant trait.
