But that's not
what the study found. If people fall into the same groups
using self-identified race as using genetics, then that could bring
down the expanding cost of medical research.

ROCHESTER, N. VirtualScopics has created a suite of image analysis tools used
in detecting and analyzing specific structures in volumetric medical images,
as well as characterizing minute changes in structures over time, providing
vital information to support clinical trials and diagnostic applications.

"We might expect
these individuals to cross several different genetic clusters," Risch
said. None of the other genetic groups could be broken
down into smaller sub-sections.

This is especially true for Hispanics who are often a mix of
Native American, white and African-American ancestry. Risch
admitted that few people in this study were of recent mixed ancestry,
who might not fall into such neat genetic categories .
Often researchers ask study participants to identify their race and
ethnicity at the beginning of a clinical trial. Risch points out that
this genetic analysis is costly. I'm looking
forward to working with the talented employees of VirtualScopics to develop a
stable and successful company .

And in each case the individuals
within those clusters all fell within the same self-identified racial
group. This information can help future doctors know which
patients may need additional disease screening or should receive one
treatment over another. Mr. Klimasewski was also a part owner of Burleigh Instruments,

The study is by far the largest, consisting of 3,636 people who all
identified themselves as either white, African -American, East Asian or
Hispanic. That's an error rate of 0.
Without knowing how the participants had identified themselves,
Risch and his team ran the results through a computer program that
grouped individuals according to patterns of the 326 signposts. This suggests that there isn't enough
genetic difference to distinguish between people who have ancestry
from northern Europe versus southern Europe , for example.

This broad distribution is important because it
means that the results are representative of racial/ethnic groups
throughout the United States rather than a small region that might not
reflect the population nationwide.

differences between participants rather than relying on race and
ethnicity .

Racial Groupings Match Genetic Profiles Stanford Study Finds

This work comes on the heels of several contradictory studies
about the genetic basis of race. Their reasoning is that genetic differences may be a more
precise tool for tracking groups of patients.

According to Neil Risch, PhD, a UCSF professor who led the study
while he was professor of genetics at Stanford, the findings are
particularly surprising given that people in both African-American and
Hispanic ethnic groups often have a mixed background. Instead, each self-identified racial/ethnic
group clumped into the same genetic cluster ., VirtualScopics, LLC, a leading

reducing costs through operating efficiencies and cost saving efforts. The
firm's proprietary software algorithms can assemble hundreds of separate
medical images taken during an MRI session into a single, three-dimensional
model, bringing a new and previously unobtainable source of data to clinical

But a new study by researchers at the Stanford
University School of Medicine finds that the checked box also says
something about a person's genetic background.
The people in this research were all part of a study on the
genetics of hypertension, recruited at 15 locations within the United
States and in Taiwan.
These two groups correlated with people who identified themselves as

What makes the current study, published in the February issue of
the American Journal of Human Genetics, more conclusive is its size.
"This shows that people's self-identified race/ethnicity is a
nearly perfect indicator of their genetic background," Risch said.
