Linear nevus sebaceous syndrome
Epidermal Nevus Syndrome
Type of disease: Rare conditions
Linear nevus sebaceous syndrome is a rare condition that affects the eyes, central nervous system, and skin. Symptoms may include seizures, intellectual disability, linear sebaceous nevus of Jadassohn (a congenital hairless plaque that is usually found on the scalp, face, or neck), hemimegalencephaly (abnormal enlargment of one side of the brain), eye abnormalities, skeletal deformities, heart defects, and an increased risk for cancer. This syndrome is sporadic, meaning that it occurs randomly by chance. Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
