Epran

From Memory Alpha, the free Star Trek reference.

Epran was a Teplan male who suffered from the Teplan blight.

When Doctor Bashir arrived in 2372, Epran volunteered to be a test subject in order to help the doctor find a cure for the Blight. Despite Bashir's best efforts, Epran died from the Blight, suffering horribly. (DS9: "The Quickening")

Epran was played by actor Dylan Haggerty.
