Summary
SINE-VNTR-Alu (SVA) retrotransposons are active in humans and linked to diseases. This review covers SVA biology, their role in disease, and their impact on the host genome.
Area of Science:
- Genetics
- Molecular Biology
- Genomics
Background:
- SINE-VNTR-Alu (SVA) elements are hominid-specific retrotransposons.
- SVAs are evolutionarily young and potentially mobilized by LINE-1 machinery.
- These elements are currently active and implicated in human diseases.
Purpose of the Study:
- To review the biology of SVA elements.
- To discuss SVA insertions associated with human diseases.
- To present a model for SVA formation and host impact.
Main Methods:
- Literature review of SVA retrotransposon biology.
- Analysis of SVA insertions in disease-associated genetic studies.
- Discussion of proposed mechanisms of SVA-mediated genomic alteration.
Main Results:
- SVAs contribute to genomic instability and disease through various mechanisms.
- Mechanisms include insertional mutagenesis, exon shuffling, and alternative splicing.
- SVA activity can lead to the generation of differentially methylated regions (DMRs).
Conclusions:
- SVAs are active mobile elements with significant roles in human health and disease.
- Understanding SVA mechanisms is crucial for diagnosing and potentially treating SVA-related conditions.
- Further research into SVA-host interactions can reveal novel therapeutic targets.

02:33Retroviruses
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
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...
03:08LTR Retrotransposons
LTR retrotransposons are class I transposable elements with long terminal repeats flanking an internal coding region. These elements are less abundant in mammals compared to other class I transposable elements. About 8 percent of human genomic DNA comprises LTR retrotransposons. Some of the common examples of LTR retrotransposons are Ty elements in yeast and Copia elements in Drosophila.

02:13Overview of Transposition and Recombination
Transposons make up a significant part of genomes of various organisms. Therefore, it is believed that transposition played a major evolutionary role in speciation by changing genome sizes and modifying gene expression patterns. For example, in bacteria, transposition can lead to conferring antibiotic resistance. Movement of transposable elements within the genetic pool of pathogenic bacteria can aid in transfer of antibiotic-resistant genetic elements. In eukaryotes, transposons can carry out...
00:36Viral Mutations
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material for adaptive...
02:57DNA-only Transposons
DNA-only transposons are called autonomous transposons since they code for the enzyme transposase that is required for the transposition mechanism. Insertion of transposons can alter gene functions in multiple ways. They can mutate the gene, alter gene expression by introducing a novel promoter or insulator sequence, introduce new splice sites, and change the mRNA transcripts produced, or remodel chromatin structure.
