Summary
This study used transcriptome-wide association studies to identify genes associated with lumbar spinal stenosis (LSS). Findings may help in early diagnosis and treatment of this common skeletal disease.
Area of Science:
- Genetics
- Skeletal Biology
- Bioinformatics
Background:
- Lumbar spinal stenosis (LSS) is a prevalent skeletal disease with a suspected genetic component.
- Current understanding of the genetic basis of LSS and its pathological changes is limited, hindering early diagnosis and treatment.
- Genetic variations are implicated in LSS, but their direct correlation with pathological changes requires further elucidation.
Purpose of the Study:
- To investigate the genetic underpinnings of lumbar spinal stenosis (LSS) using a transcriptome-wide association study (TWAS).
- To identify candidate genes associated with LSS by integrating genome-wide association study (GWAS) data with gene expression profiles.
- To explore potential genetic mechanisms contributing to LSS pathology for improved diagnostic and therapeutic strategies.
Main Methods:
- Performed a transcriptome-wide association study (TWAS) integrating GWAS summary statistics from Biobank Japan with gene expression data from skeletal muscle and whole blood.
- Validated TWAS findings by comparing candidate genes with messenger RNA (mRNA) expression profiles in LSS patients to identify common genes.
- Utilized Metascape software for enrichment analysis of candidate and common genes to understand associated biological pathways.
Main Results:
- TWAS identified 295 significant genes in skeletal muscle and 79 in whole blood associated with LSS.
- Enrichment analysis revealed associations with 112 gene ontology (GO) terms and five Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways.
- Eighteen overlapping genes, including IL15RA, and 71 common GO terms, such as negative regulation of cell differentiation, were identified between TWAS and mRNA expression profiles.
Conclusions:
- This study elucidates the genetic mechanisms contributing to the pathological changes observed in lumbar spinal stenosis (LSS).
- The identified genetic factors and pathways offer potential targets for novel diagnostic markers and therapeutic interventions for LSS.
- Findings provide a foundation for understanding the genetic basis of LSS and may guide future research in early detection and management.

13.6K
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.

15.3K
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,...

8.7K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
