Good evening Prof: Should I marry this person?

Question: Good Evening Prof, A lady friend of mine is with SC since birth and she loves this guy who is AS. Should she go on with the marriage even though there is a 50% chance of having sickly children?

Dear C.M., It is not my normal habit to advise who should marry whom, but as you can see from the kanad pictured above with male phenotypes on one side, and female on the other your friend is “SC” (abnormal Haemoglobin ACHE ‘S’ gene from one of her parents, and abnormal Haemoglobin ACHE ‘C’ gene from the other parent, making her ache with sickle cell crisis at certain times.

As you observed, when the dice ACHEACHE on one side is thrown against the dice NORMACHE on the other the probability for each throw of the dice is 1 in 2 (50%) for ACHEACHE to show because the man will show NORM or ACHE with each throw. The sequence is unpredictable because the man may show NORM (‘A’) several times or ACHE (‘S’) several times. Moreover, depending on whether the lady’s ACHE is an egg carrying ACHE ‘S’ or egg with ACHE ‘C’ the children of this union may be ‘AC’ NORMACHE, (‘A’ from the man, ‘C’ from the lady, ‘AS’ NORMACHE like your lady friend’s man, ‘SS’ ACHEACHE, or ‘SC’ ACHEACHE like your lady friend. Please read this statement again until you can explain it to your lady friend. Now, my book “The Sickle Cell Disease Patient” describes exactly such a situation where a Staff Nurse “SC” asked me whether she should go ahead and marry her lover “AS”. After explaining to her just as I have done here, she said to me: “Doctor, I am a nurse and I can care for him when he is unwell. Moreover you have told your patients how to keep out of sickle cell crisis so even if we have “SS” or “SC” children we can cope.” Remember that my kanad shown above (Konotey-Ahulu Norm Ache Dice) has two main functions:

They show you (i) What Could Happen ie PROBABILITY, and what is more important (ii) PREDICTABILITY ie What Will Happen.

If someone tells me: “Doc, I have suffered too much with this hereditary ailment. I do not want any child of mine to suffer like I am doing. Show me the phenotype that I can marry so that even though I have ACHEACHE my children will never have ACHEACHE”. Well, simple: Pick the dice marked NORMNORM and it is impossible to have an ACHEACHE child. But remember that some ACHEACHE people are brighter, more beautiful, and more focussed than their siblings who do not ache. The first option is Genetic Gambling. The second option is Predicting Genetic Certainty.

But here is a beautiful true story: One of my brilliant ACHEACHE “SS” ACHIEVERS fell in love with a NORMACHE “AS” (Sickle Cell Trait) lady. They decided to go ahead and get married hoping that the first child will be from the NORM egg of the lady, and his ACHE sperm, then they will stop, and adopt their second child. Well Mr H.S. engaged this lady, married her, and they had a son, lovely son with all the elegance of the father and the combined genius of both of them, NORMACHE “AS” Sickle Cell Trait. The couple went on to adopt a daughter.

So my duty is to show the difference between Genetic Gambling (Probability), and Genetic Prediction with 100 per cent certainty. If ACHEACHE marries ACHEACHE all the children will be ACHEACHE as shown on the cover of my blue book:

See my website Those who choose Genetic Gambling because they are madly in love should know what could happen. They will limit their family size as Mr H. S. and his wife have done.

  1. Hello Doc kindly assist me as I am in a dilemma. I’m getting married to a lady with a genotype AS while I am an AC. I understand the odds are at 50% but it still freaks me out anytime I think there is a possibility of bringing someone to this world to suffer. What are my options? I’ve read about sickling elimination where the supposed gene is taken out before the egg is fertilized. How feasible are these alternative methods? Kindly assist me.

    1. Dear Kojo T: You are exactly like my father was, and your lady is exactly like my mother was. My parents had 11 of us, with 3 suffering from Sickle Cell Disease. To check every gene before the egg is fertilised is an experimental procedure which few doctors would undertake. On the othefrhand each pregnancy could have 1 of 4 different outcomes: SC (sickle cell disease), AS (S Trait), AC (C Trait like you or my father), and AA (no abnormal haemoglobin gene). But I have said often that those with the two abnormal genes often have other remarkable genes that other siblings do not have. My two brothers and one sister who had sickle cell disease were more beautiful than the rest of us. And my younger brother with SC Disease was more brilliant at Maths than I was. And I was not bad myself at Maths. So, the decision is yours. You need to meet sickle cell disease patients who have achieved a lot in life, and will tell you how they avoided problems. Ghana has more of them than elsewhere. In Europe and USA doctors give them drugs like Morphine and Hydroxyurea and Heroin which Ghanaian patient ACHIEVERS would advise you to avoid. My advice is to discuss things with the Ghanaian Sickle Cell Disease ACHIEVERS if even you are not in Ghana at the moment. Email me privately and I shall tell you who they are. Some became lawyers, judges, teachers, doctors, and nurses. Some have not taken a pain killer for decades, and are now over 65 years of age. One SC lady died at 85 years last year. She was expert at Golf, even with hip problems.

  2. A friend of mine is 24 years and was recently diagnosed of sickle cell anaemia,she has never had any crises before.Is it possible?
