I couldnt find anything on it. The most I found was a good read at Disabilities
And this one.
LDS Disability Resources FAQ: Doctrines and Policies
"Q: Are there any gospel teachings about disabilities?
A: During His mortal ministry, the Savior and His disciples passed by a blind man. The disciples asked, “Master, who did sin, this man, or his parents, that he was born blind? Jesus answered, Neither hath this man sinned, nor his parents: but that the works of God should be made manifest in him” (John 9:1–3).
President Boyd K. Packer noted: “There is little room for feelings of guilt in connection with handicaps. Some handicaps may result from carelessness or abuse, and some through addiction of parents. But most of them do not. Afflictions come to the innocent” (“The Moving of the Water,” Ensign, May 1991, 8)."
It seems to be a good thought, but not gospel.
