Genetic testing ensures the best quality of life for children vulnerable to heritable diseases  We have a duty to the child to give it the best possible start in life, and if the technology is available to determine whether a baby is brought into the world with or without a genetic neurological disease such as Huntington’s, cystic fibrosis or sickle cell anemia, we should exercise that right.  A child that has Cystic Fibrosis (CF) produces too much fluid and mucus in the lungs, pancreas and passage ways, which then become thick, sticky and hard to move. This means that germs get stuck in the mucus and the child suffers from a lot of infectious diseases. Thus lead to reduced life expectancies (1).  For the gene detectable blood disease Thalassemia in its moderate and severe forms children may need very frequent blood transfusions, which over time lead to damage of heart, liver or other organs. Or may need stem cell transplants (bone marrow transplants) in order to get these transplants children will usually need to undergo radiation and need to have the luck of a well matched donor (2).  Congenital malformations, deformations, chromosomal abnormalities are the leading causes of 20% of infant deaths in the US. More than 6,000 single-gene disorders - which occur in about 1 out of every 200 births - such as cystic fibrosis, hemochromatosis or sickle cell anemia.  Dr. Gregor Wolbring (University of Alberta in Canada) sees embryo selection as "a tool for fixing disabilities, impairments, diseases and defects"(3).  If we have ways to prevent children from such suffering and can manipulate only with those genes so that they do not have to suffer, we should do so.  1. KidsHealth,  , accessed 05/21/2011  2.
