As soon as Mr. Confetti and I became engaged, we began joking about the genes we hoped our future children would and wouldn’t inherit from each of us. Mr. Confetti knew how to flatter me, by saying he hoped they got my eyes and my smile… cheesy I know. I hoped they would have my musical ability (which he lacks) and Mr. Confetti’s athletic ability (since I have none whatsoever). My vision – no thank you. His memory – absolutely. And our poor children, our friends would tease us, would be destined to have an intense mane of curly hair; Mr. Confetti and I both were blessed with the “Jew Fro” – full heads of thick, tough to manage curls.
Genes determine everything from hair and eye color to the shape of your toes (and hopefully our children would have mine – sorry Mr. Confetti, but your toes are weird). But also, genes can predestine an individual to have all sorts of health challenges, from the extra chromosome that causes Down’s Syndrome to the BRCA gene that predicts higher probability of having breast cancer.
All of these things can be worrisome, but in my case, my concerns about genetics were specific. I had heard from Grandma Confetti about the importance of being screened for Jewish genetic disorders, like Tay-Sachs, cystic fibrosis and many less commonly known conditions.
Because the Jewish community is a fairly small population that over the course of centuries married within their faith community, there are a handful of disorders (well, more like 3.5 hands full – there are 18 that can be tested for) that have a uniquely high rate of occurrence in Jews of Eastern European descent. While Tay-Sachs is the famous one within the Jewish population, there are other genetic disorders that have high rates in other ethnic communities, including sickle cell anemia in the African American community and thalassemia in Chinese, Indian and Southeast Asian communities.
My memories of high school biology were fairly fuzzy, so when this topic came up over dinner table discussion in the months before we began TTC, I began to worry. What does all of this mean? If I was a carrier of a disease, what would happen if Mr. Confetti was too? Would we be unable to have healthy children? Was there anything we could do? Thankfully, a bit of internet research (which for me can be a dangerous gateway drug for all sorts of worry) gave me the answers I needed to soothe my growing fears and answer all of these questions and more.
This picture from the Jewish Genetic Disease Consortium explained it clearly for me. If two parents are both carriers of a genetic disorder like Tay-Sachs, there is a 1 in 4 chance that the child could be affected by the disease, and a 2 in four chance that they could be a carrier, and a 1 in 4 chance that the child would be completely unaffected. This was already reassuring, because if one of us was a carrier and not the other, there would be 0% chance that our child would suffer from one of these disorders. Even if we both carried the gene for one of these disorders, there was still a 75% chance that everything would be okay (I tried to take the glass half-full outlook).
Where my fear set in was determining what we would do if we found out we were both carriers. As I learned more about each condition that I planned to be carrier-screened for, I understood that not every Jewish genetic disorder is an immediate death sentence. While some diseases, like Tay-Sachs, project extremely short life-expectancies for children (typically less than 5 years, fraught with suffering and pain), others, like cystic fibrosis and familiar dysautonomia, pose great challenges but have much longer life expectancies and are becoming more and more treatable as research evolves.
Traditionally when couples are ready to begin trying to conceive, the woman is tested first to see if she is a carrier for whatever disorders she is being screened for. If her results are negative, she can go ahead and try to conceive without worrying about it anymore. If she is a carrier for any of the disorders, her partner would then be screened for those specific disorders. If a couple is already pregnant, and one or both partners are part of a minority group that has ethnically prevalent genetic disorders, experts recommend that both partners are tested.
If it is found that both partners are carriers for a genetic disorder, this knowledge is power. So much has changed since Grandma Confetti was on her TTC journey. With the advancements made in reproductive technology, genetic diseases can be prevented using preimplantation genetic diagnosis in conjunction with in-vitro fertilization. This ensures that those 25% of affected embryos are not the ones implanted through IVF, thus ensuring that a baby is not born with a terminal illness like Tay-Sachs.
Not everyone is comfortable morally with preimplantation genetic diagnosis, and financially, this can be a limited option as well, depending on what insurance is willing to cover. Another option is electing to use an egg or sperm donor that does not carry the genetic material for the disorder, thus preventing the inheritance of the carrier trait from both partners. I knew this was something neither I nor Mr. Confetti would be comfortable with. Others opt to try to conceive as they normally would, but with the mental preparation to know what could be coming and the advance knowledge to prepare for early treatment should the worst case scenario arise.
Mr. Confetti and I were surprised at how easy the testing process itself was. Originally, my plan was to participate in the subsidized screening program offered by the Center for Jewish Genetics, based in Chicago. Paying for these tests out of pocket can cost thousands of dollars, and the Center offered a combined education and screening program for less than $200. Part of their initial screening process for eligibility was for me to contact my health insurance to see if the screening was covered under my insurance. At the time, I had a mediocre HMO plan, so I was shocked to find out that my screening was 100% covered.
Armed with a list of disorders to be screened for that the Center provided, I visited my Primary Care Physician, who ordered a simple blood draw. Simple as that. The doctor informed me that if I screened negative as a carrier for all of the disorders, I would receive a phone call, and if I was a carrier, I would need make a follow-up appointment with a genetic counselor to review the results.
Several days after my blood draw, I got the phone call. I had a clear panel and was not a carrier for any of the Jewish genetic disorders. Mr. Confetti was pleased, because not only did this assuage our fears, but he did not have to plan an extra doctor’s visit to get his blood drawn.
The process of TTC can bring up all sorts of concerns, and I was happy that this first step in our journey was able to alleviate one big one of mine. Certainly this was not a guarantee of good health of our future offspring, but at least we could sleep soundly with one worry off of our plates.
Are there specific health concerns you worried about when you started trying to conceive?

I went to two different OBs for preconception visits and neither of them offered me screening – my husband is Jewish, but since I’m not and I don’t have his last name, they assumed there was no risk. It wasn’t until I went to an RE and we decided to both get screened for everything possible that I learned DH is a carrier for Canavan. My RE seemed concerned about this, because if I’m also a carrier it’s not as simple to detect in Asians as apparently the mutations are different and aren’t found as consistently? (As in, if you have it they can’t always tell) I guess they couldn’t be certain that I wasn’t a carrier so there was a lot of hand-wringing, and actually for most of the disorders they were kind of uncertain about whether or not I was a carrier.

We found out that I am a carrier for cystic fibrosis, so DH had to be tested, but he got the all-clear. I think that was our only one.

At my pre TTC visit with the obgyn practice, they walked in with a pamphlet in hand about screening for Jewish genetic disorders. They obviously had me labeled based on my last name. No biggie, but I am not Jewish, my DH is. Since I am an American mutt with a million different backgrounds and we have 0 concerning elements when I created our family pedigree, I decided to forego any genetic screening. Just seemed wasteful for us. Hopefully I wasn’t wrong about this

Oh how interesting! Glad you were clear!

We recently met with a genetic counselor after learning my husband has a chromosome translocation that puts us at a high risk for Down’s syndrome and miscarriages.

So interesting! I’m glad to hear all was a-okay!

Wow, I didn’t realize there is so much that can be done to determine whether one’s children are predisposed to certain ailments!

We were told to do the testing because we’re also both Jewish. The high pricetag was deterring though, so we ended up using 23 & Me which gives lots of helpful information AND screens for all the major diseases. It also revealed that we both carry MTHFR, which is important to know for future kids.

I’m Jewish, but DH is not. I got the all clear on my blood test so we were good to go! Both of my parents are Jewish and got the screening done. They said they weren’t carriers but I just wanted to double check for peace of mind.
DH had an aunt who terminated a pregnancy because of Down’s syndrome, but that is all that was on his side.
LO does not have any disorders.

Both DH and I are Jewish, so I had the panel done. It was done through my OB’s office and covered completely by insurance. It turns out that I am a carrier for Tay Sachs and one other thing. Dh was tested and luckily he is not a carrier for anything. He likes to tease me and say that he has the good genes
I was SO relieved when we found that out, as if he had been a carrier we definitely would have had to do IVF in order to ensure that our baby did not have Tay Sachs.

My RE’s office only does the screening if the wife is Jewish. Since I have only a tiny bit of Sephardic Jewish background, they didn’t feel the screening was necessary even though DH is half Ashkenazic Jewish. Our local newspaper recently ran an article about a baby with a rare disorder. Her father is Jewish and the mother is Irish so they never thought about being tested. I wish we had had the testing done. My fingers are crossed that everything will be OK!

My husband is Jewish, and had a brother who was born with Canavan’s (he passed away at age 15). DH is not a carrier, so we did not do any additional testing. Our LO is fine, and we are not concerned about future children (because I am not Jewish), but I definitely think it’s a smart thing to do if you do have the potential for being a carrier. The more you know, that kind of thing. Thank you for taking the time to write such a thorough post about this subject!

I learned a lot about the Jewish screening process when we had our genetics scare. Mrs. confetti, you may find it interesting:

I understand that some Jewish young people actually do the screenings before marriage or dating. Is this common?

My husbands family has a history of Alpha-1, which is a genetic condition more common in people of Mediterranean descent. His father and aunt both passed away from it. It has definitely been a concern for us.

@spaniellove: I can’t imagine all of that hand-wringing. I had no idea about difficulty in screening for the Asian population. How frustrating that must have been!
@MaisyMay: so glad you guys got the all clear!
@Mrs. Sketchbook: I remember reading this post when it first came out – that must have been SO frightening, especially when you were already holding your precious baby, worrying something might be terribly wrong. So thankful that Scribble turned out to be a carrier and not anything worse.
@Pink Champagne: Wow – I have so sorry for your DH’s loss. That must have been so hard for their family. I’m glad your DH isn’t a carrier so you don’t have to worry about it.
@swedishfish: I would definitely stay positive, because the likelihood, even with two Ashkenazi parents is still quite low. Best to stay positive, since worrying can’t change much at this point (although I definitely remember the worrisome stage of pregnancy – I could worry about anything!). I hope everything is okay for you!!
blogger / pomegranate / 3491 posts
@hilsy85: I’m so glad you weren’t both TS carriers!
@highwire: I too checked mostly for peace of mind- my parents couldn’t remember being carriers for anything, but it was so long ago, that I figured better to screen than not to. Plus there are so many more disorders that can be checked for now, and since both DH and I are Jewish, I figured better to be safe…
@Mrs.Someone: I’m glad you found an affordable way to be screened!
@Leialou: I hope you had a positive experience with your genetic counselor.
@ChitownRo: That is funny that they predicted you would need it based on your last name. My OB did the same, but I was the crazy girl who came in already screened. I wouldn’t worry too much until you have to.

@Mrs. Sketchbook: I believe that is common among the Orthodox Jewish community, because it’s so small and insular, and “Dating” generally leads to marriage/kids!
blogger / pomegranate / 3491 posts
@Mrs. Sketchbook: @hilsy85: oftentimes Jewish students are tested in high school to know before dating even begins in the Orthodox Jewish community. There is a service that will do anonymous screening and compare your results to a potential “match” and tell you if you are genetically compatible (called Dor Yeshorim)
blogger / pineapple / 12381 posts
We met with a genetic counselor and did all of the paper work to determine what screening we would need. We ultimately decided that with our combination of backgrounds and genetics history that full screening would be unnecessary.
