It says in many of he articles you read approx 50 years old. I’m 58, I have family members in late 70’s and 80’s with Carney and they are still here. CNC is a relatively newly diagnosed condition, many Drs, Consultants, Specialists still haven’t heard of it. As knowledge of CNC spreads and more people are diagnosed earlier, due to the screening protocols they will follow they can get treatment for individual conditions sooner which will hopefully mean in the future that the lifespan of CNC patients will be expanded.
