Hi ARL,
I would not panic as yet. It depends on what exact rearrangement has occurred? I am not sure from your post what has occurred? A chromosomal rearrangement can take many forms for example a translocation where part of a chromosome ends up on another, or an inversion where the genes on the chromosome get shuffled. From what you have said I don't understand how it would be good for both of you to have the supposed 'abnormality'. If what you have said is correct here, i would assume its rearrangement of the genes on chromosome 16 so if you both have the same rearrangement its okay as the alleles that come together to make up the gene (one from each of you) will align. This is all i can really say given the above. Don't worry too much - what will be will be and things happen for a reason. I wish you all the best and hope everything works out.
