This genetic variation was found in the part of the genome that is responsible for the immune system.
He says that he and others working the field expected to find a pretty big amount of genetic variation.
This is a recent expansion of the work started in 2007 to build the most detailed map of human genetic variation available.
They carried out the first genome-wide analysis of the genetic variation between different regions of the same tumour using samples of kidney cancer.
Recent studies show that there is substantial standing genetic variation in natural populations of planktonic organisms, which provides the raw material for natural selection.
Of course, low genetic variation means that selection pressure is higher.
Another study found that among veterans, those who were sick were more likely to have a genetic variation that means their bodies are less able to detoxify AChEis.
ECONOMIST: Was Gulf-war syndrome caused by chemical poisoning?
Surprisingly, only 5-10% of the genetic variation present in the human species (that is, 5-10% of the 0.1% of the genome which does vary from person to person) distinguishes one "racial" group from another.
These studies have been made possible by the growth in catalogues and maps of genetic variation among human populations, as well as differences with our closest relatives, such as Neanderthal and chimpanzee.
They identified eight distinct versions of P. reichenowi (only one had been known before) and found that the DNA of P. falciparum sat nicely in the middle of all this genetic variation.
The researchers cautioned that the study was done in only one type of cancer, and that more research is needed to see how much genetic variation there is in other types of tumors.
It is also involved in the International HapMap Project, a five-country initiative launched in October, to follow up the Human Genome Project with a large-scale study of human genetic variation and its relation to disease.
It is a nice irony, given the traditional association of the naturist position with eugenic arguments, that if variation in intelligence really is caused by underlying genetic variation, then the dull are as evolutionarily fit as the clever.
ECONOMIST: Intelligence and genetics: The nature of nurture | The
What we learn from these areas is precisely how evolution has acted to sculpt bodies, but it still does so using randomly-generated genetic variation and good old natural selection (and yes, Larry Moran, genetic drift also plays a role).
The five days will see the establishment of new collaborations and discussions relating to how the objectives laid out in the Project roadmap (2012-2016) can be achieved, principally relating to the creation and maintenance of diseases specific genetic variation databases.
Some people are obese not because they eat too much but because they have a genetic structural variation.
Modern evolutionary biology as we understand it, which is to say variation via genetic drift, mutations, duplications combined with the pruning filter of natural selection, certainly explains a great deal.
Doctors say babies with this variation have a genetic predisposition to developing the disease.
It found that genetic differences account for 24% of the variation.
Approximately 50% of the variation in sleeping disorder symptoms can be pinned on genetic factors.
However, Professor Idzikowski said there was a possibility that sleepwalking could be a variation of an auto immune disorder, due to the genetic marker.
"It was certainly a surprise that it seems most of the variation in this behaviour is controlled by just a few genetic regions, " said the Harvard researcher.
While distance from Africa can explain as much as 85% of the genetic diversity of populations, a similar distance measurement can explain only 19% of the variation in phonemic diversity.
