Whole genome sequencing reveals family cancer risk
A novel germline mutation was found in the known tumour suppressor gene TP53 , and this was shown to prevent normal function of the TP53 protein. This deletion mutation was presumed to be de novo (a new mutation in the patient) as it was not present in the patient’s mother; the father’s DNA was not available for analysis, but there were no cancer cases among his near relatives. The leukaemia genome also showed a range of chromosomal abnormalities, many of them novel.
Examples of the clinical utility of WGS for patients with serious and unexplained diseases are rapidly increasing. This case is interesting because it shows the value that a whole-genome approach could offer over current, targeted forms of genetic analysis to identify mutations (especially as costs fall), and additionally the potential medical benefits to the patient’s family. Fortunately, the researchers had included an option to communicate clinically relevant information to family members in their consent documents, because it will be important for a health professional to explain the potential risks to them.

Use whole-genome sequencing (WGS) to investigate possible cancer susceptibility mutations in a patient with early onset breast and ovarian tumours and therapy-related leukaemia, who had no family history of cancer or BRCA1/2 mutations.
Entertainment News from AP Experts at the University of Alabama at Birmingham say whole-genome sequencing could lead to higher survival rates for cancer patients. Whole-genome sequencing is a process where a person's DNA is mapped and analyzed for
April 19, 2011 -- Less than a decade after the first human genome was sequenced at a cost of hundreds of millions of dollars, whole-genome sequencing is poised to become a useful and affordable diagnostic tool, experts say.
With next-generation sequencing technologies, experiments that were considered prohibitive only a few years ago are now possible. However, while these technologies have the ability to produce enormous volumes of data, the sequence reads are prone to

What is Frequency Hopping Spread Spectrum? | Article Directory
Frequency Hopping Spread Spectrum abbreviated as FHSS is a wide known radio transmission technology. In this procedure, both the transmitter and receiver leap between a predesigned set of frequencies. This is indeed a type of modulation technique and the process of switching between frequencies possibly reduces interference and also averts unauthorized intervention in telecommunication. It is commonly applied these days in local area wireless network where the signal is originally narrow in a tapered band. The signal is then modulated across a wide range of frequencies and it perhaps hops between them, during transmission in a conventional sequence. The discovery of this technique is quiet exciting and the credit goes to the film star Hedy Lamarr. During the Second World War, this was considered as the safest method to communicate information in the war field. The method initially used a piano to control frequency hops and the actress never patented the invention which lastly expired. It was later brought in again by Sylvania who named it as the spread spectrum. Devices that use FHSS technique is comparatively cheaper and are less efficient when compared with other modulation practices. The main benefit over direct sequence modulation is that there are numerous access points in the same area that keeps transmission more under control. The jump amid frequencies can be either random or it can follow a specific algorithmic rule. The transmitter and the receiver work in sync and eventually the data is transferred in a tapered band. Once the process of data transmission is over the transmitter automatically tunes to another frequency and proceeds with the methodology. The crucial point here is receiver must function effectively and in tune with the transmitter by getting the signal at the precise time. It should also hop frequency and receive signal appropriately in accordance with the transmitter. This technology, as a result uses good deal of bandwidth than when information is transmitted over a single frequency. There are certain laws in relation to FHSS and it requires companies to use at least 75 frequencies during every transmission, with an utmost reside time of 400 ms. These rules are intended to make sure that no sole device uses the same frequency for a long time and ultimately it does not utilize too much bandwidth. In this system the bandwidth is basically determined through the number of distinct frequencies employed. Consequently, the signal quality is also high when more number of hopping frequencies is available. One other important constraint is the dwell time which is vital.
