Awh, my friend! You got me with your words. Thank you! ☕
My intention was not to gain your respect, but to show you what genes can cause.

After reading all the posts last night, I came to a conclusion.
Life works in mysterious ways. Nadia was the one who got the rear disease because of the DNA match between her mother and father. If it were not for her, how many would have gotten it as there are three more grandchildren and soon they will have children? Later on, they will have children.
With technology and science, they can now test beforehand if the genes will be a match or not.

Without Nadia, it might have been discovered too late.
