An entire Italian family suffer from a strange genetic mutation that makes them almost completely immune to pain. The condition is so rare that scientists have named it ‘The Marsili Syndrome’, after the family.
Letizia Marsili, 52, became aware of her immunity to pain in early childhood when she didn’t experience any particular sensation from burns or fractures. Five other members of her family, spanning at least three generations, also share this rare genetic anomaly that makes impervious to pain situations where an average person would require an anesthetic. The Marsilis have become the focus of researchers hoping to discover how their mutation works, in the hopes of developing new ways to treat pain.
