My husband and I are in the process of doing IVF with icsi due to we both carry the Delta F508 and he carries another copy 1584 G>A. We have 2 frozen embryos frozen that have my delta F508 and my husbands 1584G>A. I cannot find much research with this combination. Our doctor said he would not implant due to the fact it could result in symptoms in a child. Even though it has not show symptoms in my husband. We are heartbroken! Does anyone out there know or have any research with this gene combination?
