Marsili syndrome (MARSIS) is an autosomal dominant pain insensitivity disorder characterized by a lowered ability to sense pain, to experience temperature, and to sweat. Affected individuals do not perceive broken bones and burns as painful, and have lowered sensitivity to capsaicin. However, visceral pain (e.g., childbirth-related) and light touch are perceived (summary by Habib et al., 2018). [from OMIM]
