We got some good news today! We learned that the cause of Nathan's DS is random and not hereditary (about 5% of cases are hereditary, or caused by translocation). So, that means we are not carriers nor is Cody. Very good news! So, if having another child is in our future, we have about a 1 in 100 chance of having another child with DS versus a 1 in 2 chance - big difference.
