Successful preimplantation genetic diagnosis to avoid creating a child affected by a genetically-based disorder was reported in 1989. Since then PGD has been used to biopsy and analyze embryos created through in viuo fertilization to avoid transferring to the mother’s uterus an embryo affected by a mutation or chromosomal abnormality associated with serious illness. PGD to avoid serious and early-onset illness in the child-to-be is widely accepted. PGD prevents gestation of an affected embryo and reduces the chance that the parents (...) will be faced with a difficult decision of whether to terminate the pregnancy. More controversial have been PGD to select the sex of the child-to-be for “family balancing”, PGD for mere susceptibility to disease and for late-onset disorders such as Alzheimer diseas, and most controversially, PGD to create a donor child who is Human Leukocyte Antigen (HLA-matched with a preexisting sibling in need of stem cell transplant.

Successful preimplantation genetic diagnosis (PGD) to avoid creating a child affected by a genetically-based disorder was reported in 1989. Since then PGD has been used to biopsy and analyze embryos created through in viuo fertilization (IVF) to avoid transferring to the mother’s uterus an embryo affected by a mutation or chromosomal abnormality associated with serious illness. PGD to avoid serious and early-onset illness in the child-to-be is widely accepted. PGD prevents gestation of an affected embryo and reduces the chance that (...) the parents will be faced with a difficult decision of whether to terminate the pregnancy. More controversial have been PGD to select the sex of the child-to-be for “family balancing” (rather than to avoid a sex-linked disorder), PGD for mere susceptibility to disease and for late-onset disorders such as Alzheimer diseas, and most controversially, PGD to create a donor child who is Human Leukocyte Antigen (HLA-matched with a preexisting sibling in need of stem cell transplant.

Clinical research with children generates special ethical concern, raising the need for additional protections beyond those for research with competent adults. Most guidelines permit research with children when it offers a prospect of direct benefit, or poses minimal risk. Unlike many other guidelines, the U.S. federal regulations also allow institutional review boards to approve pediatric research that does not offer a prospect of direct benefit when the risks are no greater than a minor increase over minimal risk. To approve research (...) in this category, IRBs must find that two additional conditions obtain:1). The intervention or procedure presents experiences to subjects that are reasonably commensurate with those inherent in their actual or expected medical, dental, psychological, social, or educational situations; and 2). The intervention or procedure is likely to yield generalizable knowledge about the subjects disorder or condition which is of vital importance for the understanding or amelioration of the subjects disorder or condition.

The U.S. Federal regulations allow institutional review boards (IRBs) to approve non-beneficial pediatric research when the risks are a minor increase over minimal, provided that the research is likely to develop generalizable knowledge about the subjects' disorder or condition. This “subjects' condition” requirement is quite controversial; commentators have argued for a variety of interpretations. Despite this considerable disagreement in the literature, there have not been any attempts to apply principles of legal interpretation to determine how the subjects' condition requirement should (...) be understood.
