Genetic mutations in HRAS, KRAS genes linked to childhood cancers

Hereditary changes in genes are often the cause of rare diseases. For example, disease-causing gene variants (PVs) in the HRAS gene cause Costello syndrome and PVs in the KRAS gene cause Noonan syndrome and cardio-facio-cutaneous syndrome. If such PVs only arise during embryonic development in the womb, those affected suffer from a mosaic disease in which both altered and healthy cells are present.
