Most of the human race marries at some point in their life. We may not like it, fret about it, go crazy , but most of us still fall for it. Many a time, it is societal pressure and expectation to be normal that leads us to do it, at other times it is LOVE, or perhaps because one simply loves the concept of family. Whatever that means!
Although things are changing in India with girls going to job and marrying late, live-in relationships becoming more acceptable etc. It is still true that marriage is a social barometer. And ones parents are happy when they see their children "happily" married.
Like it or not the "Hidden", "Hush Hush" reason why we marry, is to propagate our kind. Which parent doesnt smile inwardly when friends claim that their children look and behave JUST LIKE you! Remember that feeling? Despite our protestations to the contrary, there IS a warm FUZZY feeling.
Asians in general, South asians more specifically and Indians to get to the point, believe in this quaint notion of arranged marriages. In my experience neither a love marriage nor an arranged marriage really pips the other in terms of success rates. In case arranged marriages last longer there are mostly factors related to inertia and society pressure and personalities involved rather than anything else. Remember that the couples involved in love marriage NEED to a priori have an adventurous temperament which later in marriage may actually be a hindrance for the relationship!
Ok, so now lets discuss genetics. Throughout human history we have indirectly used genetics. Banning consanguineous marriages to avoid birth defects, relying on gotra etc have been an important part of the Indian tradition. My own view is that we have taken things too far with the Khap panchayats quelling what is a matter of personal liberty and turning it into an issue of tradition. Our thought needs to be evolve with times and a better understanding of science. The rates of disease /genetic defects claimed for consanguineous marriages are not THAT high! Really...If two people wanna marry, let them!
Anyways the issue thus is that genetics has always played a part in Indian marriages. My proposal is to take it a step forward. Genetics can today reliably understand small single letter changes in the genetics code of human beings. There are many known mutations or changes can single nucleotide polymorphisms that have been identified with risks for particular diseases. In case of some mutations called autosomal recessive, if both parents are unaffected carriers of the same defect the children have a very high chance of getting the disease. Since both parents do not have the disease itself , there is no way for both parties to anticipate that their children may have ones like Cystic Fibrosis, sickle-cell disease, among others. In case of autosomal dominant only 1 defective copy from either parent suffices for the disease to occur in children. Examples are Huntington's disease, hereditary nonpolyposis colorectal cancer and several others.
This much is classical genetics, known for quite some time. The key fact is that the genetic profile of both parents plays a role in the children's likelyhood for getting these diseases! So any potential spouse that has the same defect is a strict no-no. So why aren't there many many such children. Simply because the chance that an individual will carry these mutations is low and that he/she will marry a person with the same defect is low. However why not play safe and be sure?
Now we come to modern genetics. The human genome sequence project was equivalent in effort to NASA designing and launching a space shuttle and much of the science was developed during the course of the project. So we now know the genomes of a few people. But each of us has different DNA and a unique genome. Of course most of our DNA is the same but not all of it. DNA and the genome are made up of A,T,G, C that represent particular chemicals. In some place on the genome these change mutually. So for example on Chromosome 7, at position number 222455 in some people an A may be replaced by a C etc etc. Most of these changes are not known at present and may have no significance. But some times these individual changes also called " Single Nucleotide Polymorphisms" or Snips are significantly correlated with the RISK of developing diseases. Note that we are now talking about relative risks. And unlike the classical genetic diseases mentioned earlier, there are many environmental and dietary factors that may affect the likelihood of getting the disease. But there are now quite a few known associations between cardiovascular diseases, cancer , metabolic malfunctions etc
In general some snips reduce the risk for certain diseases for the progeny in their later life and some increase it. So what's the BIG IDEA?
Well why not get a sputum sample from eligible bachelors and anaylze all known classical mutations and also Snips? Do this for many many people all over India? Yes the consumer may have to pay for it, at least partially. So imagine now having access to a matrimonial website or perhaps marriage counsellors in Pune, who rank all the potential spouses in terms of the best match genetically. All the matches with classical genetics related VERY HARMFUL mutations will be immediately screened out. They will not appear in the results. But the ones left will be ranked in terms of lesser risk of diseases for your babies later in life!
Note tht all your regular criteria for marriages like educational and family background, looks, nature, age, religion and caste , horoscope etc will still apply. This will be an "Add-on". If you pay beforehand, then you may search the profiles free for a year!
What about the opposition and criticism about genetics in marriage. Let me respond to some.
1. It is illegal. The US FDA is turning the heat on direct2consumer genetic testing.
No its not illegal. In case of the FDA versus companies like 23andme and navigenics among others, they directly sell the genetic profile to consumers and a genetic counsellor can then advise them. There are significant psychological problems that can arise of one knows that there's a risk of cancer or dementia etc. Moreover the associations are preventable and do not doom anyone. However a case can still be made that most people will respond negatively to such information leading to unnecessary depression.
In our case the genetic profile is never revealed to the consumer avoiding the above problem. Our interest is only to use it to match other genetic profiles to maximize health benefits to the next generation.
2. Is the science perfect?
No. But only science has the guts to accept this. Are horoscopes reliable? Do most marriages turn out to be successful because they match? But most people do believe in them!
But in so far as genetics goes there is a huge amount that is already known. So why not use it to do the best we can and search for the best spouses?
3. What about ethics and who will have access to my data?
The personal profiles will never to revealed to the consumer or a third party unless explicit legal permission is granted. However, if the consumer opts out of paying the money necessary for the service, then the profile shall belong to the company.
4. How hard is it?
Well remember the Titanic scene in which Leonardo Di Caprio has a spitting competition? Not necessary. Just spit into a vial or similar and that is enough!
5. Is this not eugenics by another name?
Well it is eugenics if that means improving the genetic profile and thus the health of future generations. However, it does not endorse or tolerate discrimination on the basis of race or any other factor and does not seek to manipulate genes to enhance features or give your baby a fairer skin or blue eyes!
If you are in love, then this is not for you. Love is blind so it does not need such trifles :-). So what doe you think of the proposal? Think of this proposal as GENETIC HOROSCOPE MATCHING :-)
