God is faithfully leading us, not in a "Here is the whole big picture" way, but one step at a time. (Oh wait, that's how He tends to do things, huh?) He has led us to a doctor who is familiar with cases like Daddy's, and who has given us more information and a better working plan than we've had thus far. Praise God! We are confident that God will continue to show Himself faithful, as He always has! Thank you for your prayers!
