Noonan syndrome with multiple lentigines

Noonan syndrome with multiple lentigines is a rare multisystem genetic condition. People with this condition often have multiple small brown spots on their skin, known as lentigines. They may also experience a thickening of the heart muscle (hypertrophic cardiomyopathy), shorter stature, a chest that can have an unusual shape (pectus deformity), and distinct facial features. These physical signs can vary in severity from one person to another. This disorder affects several areas of the body. It goes by several names, including LEOPARD syndrome, which reflects some of its key features. Although it is noted as a genetic disease, detailed information about its causes and the specific genetic changes involved is not provided in the available sources.

Common signs in people with this condition include multiple lentigines (small dark spots on the skin), hypertrophic cardiomyopathy (a thickened heart muscle), short stature, pectus deformity, and unusual facial features. These symptoms help doctors consider this diagnosis, although the exact appearance and severity can vary among individuals.

Noonan syndrome with multiple lentigines is recognized as a genetic disorder. However, the specific genetic causes or risk factors have not been detailed in the available source information.
