Yrskatdon was a planet whose inhabitants were known for performing genetic engineering procedures that were illegal in the United Federation of Planets.

In the 2320s, Jean-Luc Picard and Cortin Zweller took Marta Batanides to a genetic lab on Yrskatdon for Batanides to undergo a genetic resequencing procedure to prevent her from dying from complications from her pregnancy with a Barangarian foetus.
