Living with Fabry disease — or supporting someone who does — means navigating a condition that most physicians encounter only a handful of times in their careers. The rarity of this diagnosis often translates into delayed care, generic symptom management, and a frustrating gap between what patients experience and what standard protocols address.

If you or your child has been told "it's probably RYR1" — whether after a malignant hyperthermia scare in the operating room, a muscle biopsy showing central cores, or years of unexplained hypotonia — you've likely already noticed how thin the guidance gets once the diagnosis is confirmed.

Most people who search for information on congenital insensitivity to pain are not doing so out of curiosity. They are parents who just watched a toddler chew through a lip without crying, or adults who noticed a family pattern of unexplained fractures, or clinicians trying to make sense of a case that does not fit the usual textbook categories.
