Briefings in Functional Genomics
|April 17, 2015
Summary
Genomic structural variations (SVs) are now understood to be a major source of genetic diversity, impacting more DNA bases than smaller variants. This review covers SV types, origins, and detection methods using sequencing data.
Area of Science:
- Genomics
- Human Genetics
- Bioinformatics
Background:
- Genomic structural variations (SVs) were historically underestimated as rare genetic events.
- Recent research highlights SVs as a significant contributor to genetic diversity within populations.
Observation:
- SVs affect a larger number of genomic bases compared to single nucleotide polymorphisms and other small variants.
- Structural variations play a crucial role in phenotypic diversity and the development of diseases.
Findings:
- This review provides a comprehensive overview of structural variation in the human genome.
- It details the classification, mechanisms of formation, and evolutionary origins of SVs.
- The review emphasizes methods for detecting SVs, particularly those utilizing high-throughput sequencing technologies.
Implications:
- Understanding SVs is critical for comprehending human genetic variation and its impact on health.
- Advanced detection methods are essential for accurate genomic analysis and disease association studies.
- This work facilitates further research into the functional consequences of structural variations.

Comparing Copy Number Variations and SNPs
19.4K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Single Nucleotide Polymorphisms-SNPs
20.1K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Evolutionary Relationships through Genome Comparisons
7.3K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Histone Variants at the Centromere
5.3K
Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3...

Genetic Variation
1.6K
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.
