I'm sorry. I forgot you had posted the report on the 5 year old. Sorry for the confusion. His test results are not bad for a minor. He may tire a bit more quickly than other children, but at this age he probably won't have any problems. I don't recall if you have ever mentioned if you or your wife have any problems with anemia. Do you know your own Hb levels? Beta 0 genes produce no beta globin, because they are deleted genes. This means that a child carrying both thal genes present in you and your wife, would be a thal major. There is a 25% chance of this with each pregnancy. Beta 0 usually manifests itself as noticeable anemia in carriers, unless they also carry the alpha mutation, which can help to moderate the anemia because a better balance of the two globins is produced. Sharmin and her husband both carry beta 0, but her husband has always had a higher Hb level because he also has an alpha deletion.
There is no way to predict the results of the CVS. The wait must be gut-wrenching for parents. But since you can't do anything about that, it's best not to dwell on the results, but rather objectively assess your life situation, both emotionally and financially in advance of the findings, so you have a better idea of how you want to proceed once you do know, should a decision need to be made.
