The correct answer to this open question is the following.
Your question is incomplete. You did not specify who Genie is. You did not add more information to know what you are talking about: if this is a character of a book, a character of a movie, or if it is a person or not.
However, doing some deep research trying to help you, we found that Genie is the main character of a documentary called "Genie: Secret of the Wild Child."
The documentary refers to the real-life case of a girl who spent most of her childhood in confinement, inside a bedroom. So this environment affected her ability to use language to communicate because nobody taught her how to speak, she lived alone. No examples to follow. That is why never really developed motor skills such as walking, writing, or playing. She also never develop bonds with people. She was completely isolated by cruel people. Of course, when police knew about this case in Los Angeles, California, Genie's parents were accused of child abuse.
