Insights
This study identifies six key genes (DNAH7, CLUAP1, PPA2, PAPSS1, TLR4, IFITM3) associated with severe COVID-19 and acute respiratory distress syndrome (ARDS). Understanding these genetic links aids in developing targeted therapies for COVID-19 patients.
Area of Science:
- Genomics
- Infectious Diseases
- Pulmonology
Background:
- Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, is a global pandemic with severe forms leading to acute respiratory distress syndrome (ARDS).
- Understanding the genetic underpinnings of severe COVID-19 and ARDS is crucial for effective treatment strategies.
Purpose of the Study:
- To investigate the genetic pathways involved in COVID-19 and ARDS.
- To identify specific single nucleotide polymorphisms (SNPs) associated with severe COVID-19 and ARDS.
Main Methods:
- Retrieved and analyzed over 100 patient samples from the Sequence Read Archive (NCBI).
- Utilized the Galaxy server next-generation sequencing pipeline for variant analysis.
- Performed statistical analysis including t-tests and Bonferroni correction.
Main Results:
- Identified six major genes associated with COVID-19-related ARDS: DNAH7, CLUAP1, PPA2, PAPSS1, TLR4, and IFITM3.
- These genetic findings provide a foundation for understanding disease mechanisms.
Conclusions:
- Genomic insights into COVID-19-related ARDS can facilitate early identification and treatment of target proteins.
- Discovery of novel therapeutics based on identified proteins may help mitigate ARDS progression and reduce mortality.
Abstract:
Coronavirus disease 2019 (COVID-19) is a viral infection produced by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus epidemic, which was declared a global pandemic in March 2020. The World Health Organization has recorded around 43.3 billion cases and 59.4 million casualties to date, posing a severe threat to global health. Severe COVID-19 indicates viral pneumonia caused by the SARS-CoV-2 infections, which can induce fatal consequences, including acute respiratory distress syndrome (ARDS). The purpose of this research is to better understand the COVID-19 and ARDS pathways, as well as to find targeted single nucleotide polymorphism. To accomplish this, we retrieved over 100 patients' samples from the Sequence Read Archive, National Center for Biotechnology Information. These sequences were processed through the Galaxy server next generation sequencing pipeline for variant analysis and then visualized in the Integrative Genomics Viewer, and performed statistical analysis using t-tests and Bonferroni correction, where six major genes were identified as DNAH7, CLUAP1, PPA2, PAPSS1, TLR4, and IFITM3. Furthermore, a complete understanding of the genomes of COVID-19-related ARDS will aid in the early identification and treatment of target proteins. Finally, the discovery of novel therapeutics based on discovered proteins can assist to slow the progression of ARDS and lower fatality rates.
