Since 2005, when the gene responsible for Costello syndrome – the HRAS gene – was identified,  we are also learning more about how each mutation on the gene affects the body. The most common mutation is G12S, which about 4/5 of all children who test positive for the Costello syndrome gene (HRAS) have. It appears that some mutations, like G12C, though much rarer, may be more or less affected.

The great news about our children is their sense of humor. Their charm and sheer resilience helps parents through the rough times. Read more about the syndrome in this simple to understand parent brochure
