A spectacular piece of detective work has mapped a special gene variant among Greenlanders which plays a particularly important role in the development of type 2 diabetes. The results have been published in Nature and can be used to improve prevention and treatment options for those genetically at-risk.
In collaboration with Greenland researchers from Steno Diabetes Center and University of Southern Denmark, researchers from the University of Copenhagen have carried out the ground-breaking genetic analysis based on blood samples from 5,000 people or approximately 10% of the modestly-sized population inhabiting an area larger than western Europe.
“We have found a gene variant in the population of Greenland which markedly increases the risk of developing type 2 diabetes. The gene variant is only found in Greenlanders and explains 15% of cases of diabetes in the country,” explains Professor Torben Hansen from the Novo Nordisk Foundation Center for Basic Metabolic Researchat the University of Copenhagen who conducts research into the link between our genetic make-up and the development of diabetes and obesity as well as the effect of treatment. Together with Associate Professor Anders Albrechtsen from the Bioinformatics Centreat the University of Copenhagen, he is the driving force behind the findings.
The study was a challenge in several ways. Collecting samples from 10% of the population of such a big country was a huge logistical task, and it was only possible because so many Greenlanders volunteered to participate. Additionally, the study was a statistical challenge as many of the participants are of both Inuit and European ancestry — and because many of the participants are related:
“For some of the analyses, we therefore had to develop new methods, and for others, we used methods which were only developed recently,” explains postdoc Ida Moltke from the Department of Human Genetics at the University of Chicago. She is one of the two first authors of the article and responsible for the statistical analyses.
Potent gene variant
By means of advanced gene chip technology — which over the past ten years has led to a marked increase in the speed of genetic analyses — the Danish team analysed the 5,000 blood samples for 250,000 gene variants which play a role in metabolic diseases such as diabetes, obesity and cardiovascular disease.
“Our attention was quite soon caught by a particular variant of the TBC1D4 gene which controls glucose uptake in muscle cells. Roughly speaking, this means that in carriers of this particular gene variant, the uptake of glucose by the muscles is hampered, for example after a meal which results in raised blood glucose levels. However, this particular gene variant is primarily found in Greenlanders, and about 23% of the Greenlandic population are carriers of the variant which prevents the optimum functioning of the glucose transporters in the cells. The gene variant is not found in Europeans at all,” explains Assistant Professor Niels Grarup from the Novo Nordisk Foundation Center

can you please do an updated diet and fitness video? i found this one
really helpful
thanks xxx
Do yoga! its fun :)
I wish I was like this! Since middle school I’ve been worried about my
weight! I workout usually five to six times a week and watch what I eat so
that I don’t gain weight! Oh well, and yes I love yoga and Pilates please
take both your flexibility will greatly increase and you’ll feel great!
u look like emma stone in this video :D
I am skinny and small too! Hopefully i will become pretty as you when im
older. By the way im a tween/pre teen. :)
how tall are you?
can you do a hair tutorial for this hair style? 🙂 its GORGG
“I hate the tread mill, i absolutely hate the treadmill like i really hate
the treadmill, hate it”
Can you do a video on your different curled hair styles because you almost
always seem to have a different type of curl and it is always GORGOUS!
God graced with Beauty! Gorgeous!
Great video!
Ur hair looks cute!
I love yoga!!! I don’t take classes because of my busy schedule, but I
bought a yoga disc and I do it at home. Ps- can you do a tanning video? I
really need one but I don’t know what to use
God your gorgeous
Zumba is great!! I love it! I go 2 times a week 🙂
Great Product for a Great Price!!!,

I love my exercise ball!,
I actually bought this as a “birth ball”. I’m 8 months pregnant and sitting on the ball helps relieve back pain/pressure, hip rocks feel great on it. Gently bouncing on it has gotten my baby down into position! I’ll be using the ball during labor and after I have my baby. Babies love to be bounced on it and it’s a comfortable seat to nurse on. I’ll also be using it a few months after the birth to work out on and drop my pregnancy weight.
