Genetic test results

Today we got the results from Nathaniel's genetic testing. He had Achondrogenesis type 2. You can read more about the condition if you click on the link, but basically it's an autosomal dominant gene disorder which means it's a random mutation of a specific gene. It isn't something that Mel and I are carriers of and thus we don't have to worry about future children or our children's children having this condition.
In the end it doesn't change the fact that we lost our son obviously, but I'm glad to have an answer.
