Summary
Detecting small insertions and deletions (INDELs) in human genomes is crucial. These genetic variations significantly impact human traits and diseases, highlighting their role in personalized medicine.
Area of Science:
- Genomics
- Human Genetics
- Bioinformatics
Background:
- Small insertions and deletions (INDELs) represent a substantial source of genetic variation in human genomes.
- The prevalence of INDELs is second only to single nucleotide polymorphisms (SNPs).
- INDELs contribute significantly to the total base pair variation, comparable to SNPs.
Purpose of the Study:
- To review the advancements in detecting small INDELs in human genomes.
- To emphasize the importance of INDELs in understanding human genetic diversity.
- To highlight the implications of INDEL variation for personalized medicine.
Main Methods:
- Review of recent literature on INDEL detection methodologies.
- Analysis of large-scale genomic datasets for INDEL identification.
- Comparative analysis of INDEL variation with other genetic variants like SNPs.
Main Results:
- Millions of small INDELs have been identified in human populations and individual genomes over the last decade.
- INDELs are a major contributor to genetic variation, influencing human traits.
- A significant proportion of identified INDELs are located in functionally important gene regions.
Conclusions:
- Small INDELs are a critical component of human genetic variation.
- Understanding INDELs is essential for comprehending human traits and diseases.
- The detection and analysis of INDELs are pivotal for the advancement of personalized medicine.

01:05Single Nucleotide Polymorphisms-SNPs
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,...
02:26Comparing Copy Number Variations and SNPs
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%...

02:32Exon Recombination
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes.
Exon shuffling follows “splice frame rules.” Each exon has three reading...

01:27Principles of Pharmacogenetics: Types of Genetic Variants
The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...
03:18Non-LTR Retrotransposons
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
