Genetic defect is found for rotten fish body odor...
  Scientists  have identified  genetic  defects  that make people smell like
rotting fish, an uncommon disorder that can lead to ridicule, loneliness and
depression.
  "These  people lose jobs, they lose friends, they're often very isolated,"
said  Dr. Eileen Treacy of McGill University in Montreal, who led one of two
competing research teams that found the flaws in a single gene.
  No cure is known for "fish-odor syndrome." The liver needs the enzyme FM03
to process a smelly protein called TMA, or trimethylamine, which is produced
by bacteria in the gut. When TMA goes unprocessed,it seeps out in a person's
breath and perspiration, causing the offensive body odor. It's not clear how
common fish-odor syndrome is. - Associated Press - Compiled by Sean Jamieson
