If an aniridic has a child, what are the chances of that newborn child having aniridia?
Unlike most genetic conditions, aniridia is dominant. It only takes one parent to have the mutation or deletion to pass on this condition. Therefore, the chance of an aniridic man or aniridic woman having an aniridic child is fifty (50) percent. If an aniridic should have a child with aniridia, the condition is called “familial” aniridia, because it was passed on by an aniridic parent. Currently, there is the possibility of identifying the mutation or deletion in the PAX 6 gene and using egg or sperm sorting to try to stop the aniridia from being passed on. This technology is very new and not much is known about its success rate.
