Summary
This study identified numerous single nucleotide polymorphisms (SNPs) in genes linked to spinal cord injury (SCI) pathways. Some identified SNPs show significant frequency, suggesting their role in neuronal damage after SCI.
Area of Science:
- Genetics
- Neuroscience
- Bioinformatics
Background:
- Spinal cord injury (SCI) research has not extensively explored genetic variations.
- Understanding genetic factors in SCI neuronal damage is crucial for developing targeted therapies.
Purpose of the Study:
- To identify gene polymorphisms (SNPs) associated with neuronal damage pathways in SCI.
- To provide a foundation for future genetic investigations into SCI pathogenesis.
Main Methods:
- Data mining of single nucleotide polymorphisms (SNPs) within gene pathways relevant to SCI using Gene Ontology.
- Gene mapping and identification of polymorphisms in the SNP database.
- Genotyping a subset of SNPs in genes (ALOX12, APOE, BDNF, NINJ1) in SCI patients and controls.
Main Results:
- Identified 95,276 SNPs across 588 genes linked to selected Gene Ontology terms.
- Discovered 3912 nucleotide alterations within gene coding regions.
- Observed significant frequencies for five non-synonymous SNPs, indicating their potential relevance to SCI evolution.
Conclusions:
- Single nucleotide polymorphisms (SNPs) represent an underexplored area in SCI research.
- This study presents a valuable set of SNPs potentially involved in the genetic mechanisms of post-traumatic spinal cord damage.

Comparing 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%...

Single 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,...
Spinal Cord Injury ll: Pathophysiology
Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...
Genome-wide Association Studies-GWAS
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.
