Kids while dying

My husband and I want to have kids, however I have a degenerative condition that will make me wheelchair bound in the next 10 years and likely dead within the next 15 years. There is no treatment or cure for my condition. We are financially sound, have great support in family and friends. Normal, happy people who grew up in great homes, and my husband really wants kids and I do too. AITAH for bringing kids into the world knowing that I am setting them up to be motherless at ages 13 and 11 years old (based on our timeline and my diagnosis)?

Edit: it is genetic but we would do IVF with PGT-M testing to ensure the embryo we implant does not have the gene.
