Earlier this month, Prince Félix and Princess Claire assisted at the general assembly of the organisation Le Sourire de Lucie. The couple are the honorary presidents of the French organisation which supports families with children who suffer from the Larsen syndrome, "a rare genetic disorder that has been associated with a wide variety of different symptoms. Characteristic findings of the disorder include dislocations of the large joints, skeletal malformations, and distinctive facial and limb features."
