The National Center for Rare Diseases and Diagnostic Networks
Italy has established a robust framework for diagnosing rare genetic diseases through the National Center for Rare Diseases, based at the Istituto Superiore di Sanità (ISS). This center coordinates a nationwide registry that tracks thousands of rare conditions, many of which are identified through genetic testing.
The "Interregional Networks" for rare diseases facilitate collaboration between different parts of the country. For example, a patient in a smaller region like Valle d'Aosta can have their sample analyzed by a specialized lab in Piedmont through a shared diagnostic pathway. Programs like the "Undiagnosed Diseases Programme," supported by foundations like Telethon and the Tigem Institute, specifically target children with mystery illnesses. These programs use "Multi-Omics" (combining DNA, RNA, and protein data) to find answers for families who have been searching for a diagnosis for years, often providing a "name" to a condition for the very first time.
