One gene leading to many different phenotypic expressions. An excellent example of a gene with pleiotropic effects is the gene for myotonic dystrophy. Affected individuals can have one or more of a range of signs and symptoms including characteristic Christmas-tree like cataracts, myotonia, narcolepsy, testicular atrophy, frontal balding, mental retardation, and cardiac abnormalities, among others.
