Prince Frederik from Luxembourg has passed away at just 22 years old after battling a rare genetic condition.
Frederik was the son of Prince Robert, Grand Duke Henri’s cousin, and had been diagnosed at age 14 with POLG mitochondrial disease — a disorder that drains the body’s cells of energy, which in turn causes multiple organ dysfunction and failure.
His family released a statement published on POLG Foundation’s website, which he founded three years ago in an effort to raise awareness of his condition, informing the public that their beloved prince had passed on the first of March.
