Summary
Copy-number variations (CNVs) in non-coding DNA regions were analyzed. Researchers found mostly local correlations between these genetic changes, with some random long-distance connections detected.
Area of Science:
- Genetics
- Genomics
- Bioinformatics
Background:
- Allelic DNA aberrations, including copy-number variations (CNVs), contribute to human genetic diversity and disease.
- While CNVs in coding regions have understood gene relationships, those in non-coding regions lack functional correlation insights.
Purpose of the Study:
- To investigate correlations between CNVs in non-coding, extragenic regions of the genome.
- To characterize the nature of these correlations, whether local or long-distance.
Main Methods:
- A signal processing approach was employed for copy-number variation detection.
- Distributed CNVs in short, non-coding regions across chromosomes were identified and analyzed.
Main Results:
- Predominantly local correlations between CNVs within the same chromosome were estimated.
- A small number of seemingly random long-distance correlations between CNVs were also observed.
Conclusions:
- The study highlights that CNVs in non-coding regions exhibit primarily localized correlations.
- Understanding these quantitative correlations is crucial for characterizing extragenic genomic variations.

02:26Comparing Copy Number Variations and SNPs
18.5K
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%...

01:05Single Nucleotide Polymorphisms-SNPs
17.7K
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,...

02:46Genome Copying Errors
4.9K
DNA replication is a well-evolved process that copies millions of base pairs with high fidelity during each cell division. Occasionally a wrong base or a long stretch of wrong bases may get added to the daughter strands. If the errors are left unchecked, cells might accumulate several mutations that might endanger their survival. Therefore, the copying errors are checked and repaired at three levels.

01:11Genome-wide Association Studies-GWAS
15.1K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

02:37Gene Duplication and Divergence
7.7K
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...

20.4K
Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...
