Updated Database of DNA from the FBI under Fire Plans federal bureau
A major update of the Federal Bureau of Investigation (FBI) system for DNA database is under fire from members of the legal community. federal bureau
federal bureau CODIS system is used to generate genetic profiles stored in the national DNA database of the United States
FBI wants expand the number of genetic markers federal bureau used to classify the DNA of individual Codis.
But the former head of science at the office says that the plan has not been driven researchers 'needs'. federal bureau
federal bureau Dr. Bruce Budowle, with Arthur Eisenberg and colleagues Jianye Ge, explained the purpose of Promega 22nd International Symposium on Human Identification (Ishi) in Maryland , USA
Another researcher told BBC News the changes were very important, because it would drive like the DNA has been registered in the U.S.
While working with the FBI in 1990, Dr. Budowlani helped to select the genetic markers currently used by Codis. federal bureau
Check gap
He said that the review is a good idea, but the choice of markers for forensic law is essential. federal bureau

If you have a degraded sample, and do not understand, it's useless "
Bruce Budowlani federal bureau
He told BBC News that the FBI did not adequately consult the community of forensic science before making its recommendations. federal bureau
"The first time we have adopted an approach at Community level - 21 laboratories for the handling of the sleeves, and providing data that we could analyze, and [to] make decisions," said Dr. Budowlani, University of North Texas Health Science Center in Fort Worth. federal bureau
"This time, they formed a group of about five [scientists] and the FBI, the person to decide what should be a core. federal bureau
"If the needs of Codis - our national database system - to run the processes in the case or cases should be need driven processes Codis? federal bureau
"I hope the latter is clearly what to do." federal bureau
High Profile
The national database of the U.S.
CODIS (which stands for System Combined DNA Index) uses the set of 13 genetic markers - known as the "core loci" - for the production of DNA of an individual. federal bureau
CODIS database of the FBI is the largest in the world federal bureau
In May 2010, the FBI established a working group of six men to examine the loci used for basic research database. It has now recommended that the current set of 13 markers increased to 24 years. federal bureau
Significance of these signs indicated the British man was arrested in 1999. His DNA matches that collected in a robbery compared to six genetic loci. federal bureau
The suspect spent several months in prison before his lawyer demanded a marker of 10 re-test. The suspect left the burglary suspects on one of the four additional markers and was released. federal bureau
Although the probability of matches opportunities for individuals such employment is relatively small, they increase the DNA databases grow in size. federal bureau
In addition, certain genetic markers are better for certain tasks than others, said Dr. Budowle, who said what he said were inconsistencies in the selection of base loci. federal bureau
Dr. Budowlani said that some of the signs of old and new systems Codis composed of large fragments of DNA so that they can be difficult for forensic scientists to detect the DNA at the crime scene - which may be subject to degradation, or may be present in small quantities. federal bureau
Although a large fragment of the signs are informative, Dr. Budowlani said, "if you have samples of the poor, and do not understand, it's useless." federal bureau
He added: "analysts [my shop] to me all the time in difficult cases, it is said a large fragment of it:" .. Get rid of them because it did not work "" federal bureau
He also said that the new system is bypassed informative markers on the (male) of the Y chromosome, which would be useful to search for family - a technique used when researchers have not found an exact match for a sample of DNA database. federal bureau
Family research is based instead, to find nearby, but not perfect, the games that might be close relatives of the suspect.
Difficulties Loci federal bureau
Laboratory, the FBI spokesman declined to comment directly to the presentation of Dr. Budowlani. federal bureau
However, Dr. Douglas A. Hare, from the FBI lab in Quantico , Virginia
Genetic markers should be chosen carefully depending on the task in hand federal bureau
The amendments increase the power to distinguish between individual profiles and reduce the likelihood of random matches. federal bureau
The Office will also increase compatibility with international databases to allow cross-border exchange of information - increasingly important in the fight against terrorism. federal bureau
federal bureau Dr. Hare has said that the group had shown objective criteria for accepting new markers, and had heard the kit manufacturers DNA analysis. federal bureau
