They’re not making the pig more human, they’re removing the markers of ‘foreign’ that would make it an immune target. So it’s a nice vanilla organ that minimally attracts the attention of the immune system.

Six human genes were added to prevent blood from coagulating in the heart, improve molecular compatibility and reduce the risk of rejection.

So they actually did make the pig a tiny bit human.
i'm not the poster you're replying to, but for me the answer is this :
consciousness appears to me to be a constellation of traits rather than a trait itself that would be easily acquired with a genetic shift.
One could then say : 'What if the one we flip is the thing that finishes the constellation of traits that activates consciousness?' , and sadly I must confess that I believe that if that were to happen to an entity without sufficient communications methods that it would probably remain unknown and subject to whatever experiences whatever sensory organs it may have provides it, while we remain entirely unaware for some time.
Also, a point that I agree upon by the poster who replied to you with me ; we don't seem to hold conscious entities in very high regard -- only human ones.
The words you're looking for are sentience or even sapience.
