Many disability activists see this as discriminatory. One resolution would be to allow testing and selective abortion under the same gestational time limits, for all traits and disabilities, including gender, hair color, Down Syndrome, dwarfism, etc. The Foundation for Blood Research has just announced the development of a blood test for Down Syndrome that could be used in the first trimester, to make abortion easier, medically and psychologically. So in the future, the technology will be such that relatively common conditions would be detectable in the first trimester. It would remain important to ensure that there is equity in the gestational limits of termination.
Dwarfism is on the cusp between disability and trait.
Many dwarfs are just really short and do not have many medical or disabling complications, but still face social discrimination. The gene mutation for achondroplasia, for instance, causes about half of the instances of dwarfism, and will probably be included in the DNA chip under development that will test prenatally for the 100 most common types of so-called birth defects. When this happens, the parents often are told inaccurate things, in insensitive ways, about the baby, in terms of whether or not it will have a dwarfing condition, the specific diagnosis and severity of health concerns. Dwarfism is a characteristic that is prone to human genetic enhancement. Already there is growth hormone and limb-lengthening surgery, which have medical indications for specific conditions, but now are being pushed for merely increasing height.
