This table illustrates the rate of embryo aneuploidy in the subgroup of unaffected and affected embryo diagnosed for monogenic disorder. Though there is no significant defference of aneuploidy rate between the two groups (P < 0.05 where * noted), among those embryos diagnosed as unaffected for monogenic diseases, 26.5% (31/117) of the embryos were aneuploid and could not be transferred.
