Modern innovations in the field of medicine mean that doctors are now able to identify genetically transferable disabilities in a couple before they have children. Such disorders are found in around 3-5% of the general population.
In addition to preventing dangerous disorders prior to conception, modern screening can also help to identify the risk of a number of disorders that occur due to recessive genes that are found in the parents and which can be transferred onto their offspring. This is particularly true of thalassemia. If either parent is found to be in possession of this recessive gene or either of them is a carrier of the gene, the chances of their child being born with the condition are extremely minimal. However, if both parents have this gene present or if they are both carriers of the gene, the chances of their child being born without the condition are just 25%, while their chances of that child being a carrier of the gene are 50%, meaning the chances of their child being born with thalassemia are also as high as 25%. Moreover, in cases where both parents suffer from thalassemia, their child is 100% certain to be born with the condition, for which there is currently no cure available.
Therefore, preconception genetic testing can play a crucial role in helping parents decide whether or not to proceed with their pregnancy, as well as giving them the opportunity to consult with a medical professional about potential preventative techniques they could carry out prior to conception.
