What is Creatine Transport Deficiency explained on Beast Games?

On Episode 8 of Beast Games, Player 831 Jeffrey Randall Allen opened up about his son Lucas' 'rare' brain condition, Creatine Transport Deficiency. Jeff further mentioned that the disease is "currently incurable" in the medical field. His exact words were:

"It's a rare brain disease that's currently incurable and his brain doesn't get the energy it needs to function and develop. So, he's not like your everyday seven-year-old. You know, developmentally, he's probably under two. It's just a devastating disease."

Jeff also added that he wants to find the cure not only for his son but probably hundreds of other individuals upon whom this deadly disease has been inflicted. Viewers also learn that Jeff's older son Jack introduced him to the show and made him watch Mr. Beast's YouTube videos. As mentioned by Jeff on Beast Games, Jack was the reason he was there and the latter has been a 'coach' to him all the while.

The top 10 Beast Games participants revealed by Mr. Beast on Episode 8 are as follows:

• Player 424 aka Courtney Ferris

Out of these 10, only 6 would make their way to win the $5 million after the tower climbing challenge round. The game involved players alloting numbered houses to each other without having any knowledge of what actually the numbers signified. There was a cash pot stuffed with $1 million and the order in which the contestants got the houses would determine how much they would want to pick from the bank.

Jeff, who drew 6, hoped that the participants preceeding him would not be insensitive enough to take away a lot of money—given his situation that he mentioned earlier. However, things went the other way and Jeff's luck left him only $22,000 which came down to around 7 grand after the calculations. It was later revealed that Player 566 aka JC took a major amount from the cast pot.
