Quantifying tumor heterogeneity in whole-genome and whole-exome sequencing data
MOTIVATION Most tumor samples are a heterogeneous mixture of cells, including admixture by normal (non-cancerous) cells and subpopulations of cancerous cells with different complements of somatic aberrations. This intra-tumor heterogeneity complicates the analysis of somatic aberrations in DNA sequencing data from tumor samples. RESULTS We describe an algorithm called THetA2 that infers the c...
متن کاملWhole exome and whole genome sequencing.
PURPOSE OF REVIEW The purpose of this review is to describe the new DNA sequencing technologies referred to as next-generation sequencing (NGS). These new methods are becoming central to research in human disease and are starting to be used in routine clinical care. RECENT FINDINGS Advances in instrumentation have dramatically reduced the cost of DNA sequencing. An individual's entire genome ...
متن کاملComparing whole genome sequencing and exome sequencing
Introduction Next-generation DNA sequencing empowers scientists to identify genetic variations associated with human disease at higher resolution and greater sensitivity than previously possible. Two approaches are commonly employed -exome sequencing and whole genome sequencing. Exome sequencing targets protein-coding regions comprising approximately 1% of the human genome, while whole genome s...
متن کاملWhole Exome Sequencing for Mutation Screening in Hemophagocytic Lymphohistiocytosis
Background: Hemophagocytic lymphohistiocytosis (HLH) is an immune system disorder characterized by uncontrolled hyper-inflammation owing to hypercytokinemia from the activated but ineffective cytotoxic cells. Establishing a correct diagnosis for HLH patients due to the similarity of this disease with other conditions like malignant lymphoma and leukemia and similarity among its two forms is dif...
متن کاملWhole-exome/genome sequencing and genomics.
As medical genetics has progressed from a descriptive entity to one focused on the functional relationship between genes and clinical disorders, emphasis has been placed on genomics. Genomics, a subelement of genetics, is the study of the genome, the sum total of all the genes of an organism. The human genome, which is contained in the 23 pairs of nuclear chromosomes and in the mitochondrial DN...
