Back
a couple of years ago I had a DNA test done by Ancestry.com and along
with the information about my ancestry, I also got my raw data which
can be uploaded to learn more about traits and personality. One of
the places I recently tried out is GENOME
LINK which is based on the power of the data you upload which
gives us even more information about our DNA. The reason they can
provide you with more data on various genetic traits is that they
read more various research papers about genetic traits. And also they
can read whole genome data only if you upload whole genome data but
again 23andme or Ancestry.com only read the limited parts of your DNA
so the data that you download is not whole genome.
I
actually found GENOME LINK through
an advertisement on Facebook and thought why not try it out? I
uploaded my raw data I got from Ancestry.com. This part is really
easy. You get your raw data and it is usually a text file or
something similar. You then upload it and the results are pretty
immediate.
The
kind of information you get are 26 traits like eye color, skin
pigmentation, weight, hair color, caffeine consumption and if you
upgrade to Premium plan, you get additional 40 traits, even things
like longevity, sleep duration and excessive daytime sleepiness based
on your genome data. Now, keep in mind that some things won’t be
exact and there is a reason for this.
The insights derived from the research studies used to interpret your
DNA data is based on population studies whereby they recruit research
participants who all have the same trait (eg. have a certain eye
color). Then they compare all their DNA data and see where in the
genome they are aligned, or have the same nucleotide (DNA letter).
This, combined with other studies, allows researchers to conclude
that MOST people who have a certain nucleotide at a specific position
in the genome have this trait (eg. brown eye color) that they are
researching. And that MOST people who have other nucleotides at this
specific position have another variant of the trait (eg. other eye
colors). In short, they identify which variants in DNA are associated
with traits. You can link to these research papers by clicking a
certain SNP on each traits card on GENOME
LINK.
SNP (single-nucleotide polymorphism) is a DNA sequence variation
occurring when a single nucleotide adenine(A),
thymine(T),cytosine(C),or guanine(G) in the genome(or other share
sequence) differs between members of a species or paired chromosomes
in an individual. For example, two sequenced DNA fragments from
different individual, AAGCCTA to AAGCTTA, contain a
difference in a single nucleotide. In this case we say that there are
two alleles: C and T. Almost all common SNPs have only
two alleles.

Just
because the data does not return what you believe to be your trait,
it does not mean that it is wrong. It is likely that you are
statistically one of the few people who have the trait regardless of
the nucleotide letter, for some reason unknown to science, or that it
was affected by other factors such as epigenetics, the environment or
other. Remember that the bulk of these studies only show correlation
and not causation. It is unsettling that science cannot be
more conclusive, but that's how far science is at this point.
There
is a raw data tab in the left corner of the screen that allows you
view your raw data where you can link to public databases on research
papers. This is especially important because it is another factor in
having the most information possible and I don’t know of any other
place where you upload raw data that actually links to outside
resources.
DNA
and genomes are pretty exciting in my opinion – especially since I
am adopted and have no family history. The technology will continue
to grow and at some point in the future, you will pretty much know
everything you need to know in order to make good decisions on what
to eat and things that will help you live longer and healthier.
If
any of my friends have done a DNA test and would like to try out the
premium version of Genome Link, I have five premium versions to
offer. Just let me know. Either way, check it out and see how cool it
is to learn more about your genome.
