What have we learned from next generation sequencing of cancer genomes?

What can we learn from sequencing cancer?

Additionally, genomic sequencing has revealed the complexity of the cancer genome and has enabled the discovery of functional rearrangements with therapeutic and diagnostic potentials.

What can you learn from genome sequencing?

By sequencing your genome, health professionals can look at the unique variations found in your genes. … For example, a doctor or genetic counselor could use whole genome sequencing to see if a patient has a genetic disorder or is at risk for a disease. Whole genome sequencing is different than gene sequencing.

What is the importance of next generation sequencing?

Next-generation sequencing, in contrast, makes large-scale whole-genome sequencing (WGS) accessible and practical for the average researcher. It enables scientists to analyze the entire human genome in a single sequencing experiment, or sequence thousands to tens of thousands of genomes in one year.

Can genome sequencing predict cancer?

Summary: Whole genome sequencing of tumour cells could help predict the prognosis of a patient’s cancer and offer clues to identify the most effective treatment, suggests an international study.

What are the risks of whole genome sequencing?

Vassy acknowledges that routine genome sequencing could overwhelm doctors and patients with confusing and sometimes alarming information, leading to anxiety and stress, as well as expensive and sometimes dangerous follow-up testing.

What can DNA sequencing tell us?

DNA sequencing is a method used to determine the precise order of the four nucleotide bases – adenine, guanine, cytosine and thymine – that make up a strand of DNA. These bases provide the underlying genetic basis (the genotype) for telling a cell what to do, where to go and what kind of cell to become (the phenotype).

What can DNA sequencing reveal?

The sequence of DNA can reveal lots of genetic information, helping identify genes that code for proteins, regulatory instructions that can instruct genes to turn on or off, as well as mutations that can cause disease.

What are the limitations of next generation sequencing?

For many of the identified abnormalities, the clinical significance is currently unknown. Next-generation sequencing also requires sophisticated bioinformatics systems, fast data processing and large data storage capabilities, which can be costly.

What percentage of cancer is genetic?

Hereditary Cancer Syndromes

Inherited genetic mutations play a major role in about 5 to 10 percent of all cancers. Researchers have associated mutations in specific genes with more than 50 hereditary cancer syndromes, which are disorders that may predispose individuals to developing certain cancers.

How do cancer cells come back?

Cancer may sometimes come back after cancer drug treatment or radiotherapy. This can happen because the treatment didn’t destroy all the cancer cells. Chemotherapy drugs kill cancer cells by attacking cells that are in the process of doubling to form 2 new cells.
