Disintegrate deals X damage to target creature or player. That creature can't be regenerated this turn. If the creature would be put into a graveyard this turn, remove it from the game instead.

World Championship Decks 1997

Disintegrated creatures do not go to the graveyard at all before being exiled. They do not trigger abilities which trigger due to a creature going to the graveyard.

The “can’t regenerate” is an effect of Disintegrate and not an effect of the damage. It works even if the damage is prevented or redirected. If redirected, the damage does not take this effect with it.
