Vestergaard et al have reported dermoscopy assessment is more accurate than clinical evaluation by naked eye for the diagnosis of cutaneous melanoma (odds ratio = 15.6, P = .016). In this study, the mean sensitivity in the diagnosis of melanoma was 74% for the examination by naked eye and 90% for dermoscopy.

A genetic brain disorder is caused by a variation or a mutation in a gene. A variation is a different form of a gene. A mutation is a change in a gene. Genetic brain disorders affect the development and function of the brain. Some genetic brain disorders are due to random gene mutations or mutations caused by environmental exposure, such as cigarette smoke. Other disorders are inherited, which means that a mutated gene or group of genes is passed down through a family.
