Objectives: The research aimed to determine whether the genes that presented with nystagmus as part of their clinical presentation were differentially expressed in the brains of patients with Parkinson’s Disease (PD), Chronic Traumatic Encephalopathy (CTE), and Alzheimer’s Disease (AD).
Methodology: The data was derived from the available NCBI SRA datasets that allowed public domain use. The RNA sequence from the brain samples of the patients underwent differential expression analysis using the web-based platform Galaxy and R version 4.1.0 with R Studio.
Results: There were only 19 genes out of the 28,395 retrieved genes in the patient groups and the control group that had significant under-expression in the patient group compared to controls (p<0.001). The genes that were identified can be divided into those involved in protein synthesis, cell cycle regulation, gap junction formation, transcription regulation, signal transduction, and synaptic function.
Conclusion: Performing differential gene expression studies in the brain samples of post-mortem cases illustrate how autopsy pathology and neuroinformatics can elucidate the common genomic changes and molecular mechanisms that can present across different diseases which may have future significance in the field of both neuro- and ophthalmic pathology.
