Every year on my Twitter feed, I see a tweet about how important it is to know your genotype, as well as your partner’s. I agree with the rationale for this; it’s important to be as prepared as you can when dating. Understanding how genotypes work means you can prevent passing on genetic conditions like sickle cell disease to the next generation.

Unfortunately, these discussions can often take a dark turn, as some people believe health screening takes away from the organic nature of dating. In some comments, I’ve seen this form of screening referred to as eugenics. “Selecting for genes is unethical,” they say.

As a patient with sickle cell, I do not agree with this thinking.

From my own experiences, I understand how painful living with a condition like sickle cell is. It affects every aspect of one’s being, from mental to physical health, and there is no telling how severe it will be. I would hate to pass on sickle cell to my future children, knowing how it has affected me and others in the community.

My parents both have the sickle cell trait, but they had no idea because they had no symptoms. They had a 25% chance of having a child with sickle cell, and that’s what fate decided for me at birth. Genotype testing wasn’t as common back then, so I understand they didn’t realize the gamble they were taking. But for me to do the same with the knowledge I have feels irresponsible.

Therefore, the decision to have children is a well-considered process for me. I couldn’t bring anyone into this world to suffer from sickle cell the way I have. Asking potential partners early on “what is your genotype?” allows me to decide how to proceed.

I have researched my options if I did want to start a family with someone who has the sickle cell trait.

Diagnostic tests

As I have sickle cell disease (HbSS genotype), if I were to have children with someone with the sickle cell trait (HbAS genotype), there is a 50% chance the child would get the sickle cell trait and a 50% chance they would get sickle cell disease. Having a child through natural conception would require having a diagnostic test from 11 weeks into the pregnancy to find out whether the child has sickle cell or not.

Finding out at this stage would be difficult for both parents. This wouldn’t be an option for me because of my personal beliefs.

IVF with preimplantation genetic screening

In vitro fertilization (IVF) with preimplantation genetic screening is one method to prevent having a child with sickle cell before conception. Embryos are taken from the mother, fertilized, and then screened for sickle cell. The embryos that do not have the full sickle cell gene are selected.

At first, I felt this would be a viable option as we could prevent the possibility of offspring inheriting sickle cell. Researching further, however, I realized the considerable strain on the mother to get the conditions needed for a successful procedure. IVF doesn’t have a 100% success rate, so the emotional and physical toll would be immense.

There are a considerable number of risks and preparations for this option, and I’m simply not comfortable with them.

Adoption or surrogacy

Not everyone has the ability to have their own child, and not everyone wants to. Adoption is another option I have thought about because I wouldn’t be passing on the sickle cell gene. If I were to date someone with the trait, I would strongly consider this option. I’ve always had a strong desire to create my own family, and I recognize there are many ways to do this.

In an ideal world, I wouldn’t have to think about these things and there would be an easy and inexpensive alternative. At the end of the day, I’m a strong believer in knowing your genotype and making the right decisions to support the next generation.

What that looks like will always be a personal choice, but it’s important to be informed.

I am afraid, the article gives a prescription, it has given three options though. It is important to mention that one with SCD should look for someone neither having the trait nor the disorder and marry such a person. Of course, it may be difficult to get one who will be willing to marry one having SCD. The society must be educated and people should come forward to help the future generation.

Hi K thanks for your comment. I agree, my stance is to ideally be with someone without SCD or the trait. However, I recognize there are those that have a different view or stance. I wanted to highlight options to consider that prevent passing on the disorder to the next generation in that scenario. Education is key.

My wife and I are autosomal recessive carriers of a rare disease. We have one daughter who suffers from AADC. We always wanted a large family and consider the same options as you mentioned. Based on the promotional materials from IVF clinics, it seems perfect, but you have to read the fine print. In Thailand, they usually use multiple embryos to ensure one is "viable" and then discard the rest. This is not an option for us and also does not align with our beliefs. We have since dedicated time to volunteering with children but may consider adoption. Thank you for sharing this important topic.

Hi Richard, thank you for sharing your experience. I really appreciate your perspective, I hope you find the option that works for you!
