No - there is a huge difference between reproduction with mosaicism and
translocations. With mosaicism the child can be typical or full - the only
two possibilities. Not so with a translocation. And I am not even going to
attempt to answer this one because there are way too many variables
depending how the unbalanced translocation sits on the chromosomes. Without
seeing the exact kayotype there are too many variables. Safer to think along
the lines of a Robertsonian translocation, in that you could have a child
with a balanced translocation, or an unbalanced translocation, or a monosomy
(universally fatal). Depending on how the unbalanced translocation sits its
even possible to have "normal".

I wouldn't even hazard a guess depending on the situation, that is that the
child is in EI - that could simply be to help the mother in providing
learning opportunities. Happens a lot here with children "at risk".

I have not lost my mind - it's backed up on disk somewhere.
