How to identify driver mutations

 · The field is also moving towards cancer-specific driver identification, because different cancer types are characterized by different driver mutations. A patient’s therapeutic response to drugs targeting a specific gene and optimal assignment to a clinical trial is increasingly understood to depend on both the specific mutation in the gene of.  · Three approaches to identify combinations of driver mutations are: (1) to identify recurrent mutations in predefined groups (such as pathways and protein complexes from databases); (2) to identify recurrent mutations in large protein-protein interaction networks; (3) de novo identification of combinations, without relying on a priori definition of gene sets. Cited by:  · As said, detecting driver mutations in cancer is not easy, mainly because of the high level of genetic heterogeneity of tumors. Driver mutations may be present in just few cells, so high levels of coverage depth are usually necessary when sequencing the tumor DNA. In order to identify driver mutations, sequencing should run at coverages between x and x. .

The definitions of driver and passenger mutations were formally introduced by Stratton et al., who define a driver mutation as a mutation that is directly implicated in carcinogenesis by its ability to confer a growth advantage to tumor cells and is, therefore, positively selected in a mixed cell population and a passenger mutation as a mutation that does not confer a growth advantage to tumor cells and, therefore, will not contribute to the development of cancer. The search for driver mutations usually revolves around the detection of key amino acid residues for the function of proteins, –often specifically a subset of proteins known or susceptible to be involved in tumorigenesis.

When anyone needs a ride home, taxi, ride-share and limo drivers always lend a hand. While driving, these hard workers meet a slew of people from different backgrounds. And with so many different riders, there's always someone new making th. A gene mutation is a permanent change in a DNA sequence.
