ABSTRACT
BACKGROUND: Amyotrophic Lateral Sclerosis (ALS) is a rare neurodegenerative disease that affects motor neurons and promotes progressive muscle atrophy. Vascular Endothelial Growth Factor A (VEGF-A) plays multiple roles in the central nervous systems (CNS). The purpose of this study was to evaluate the association between single nucleotide polymorphism (SNP) VEGF-A rs28357093 and ALS.
METHODS AND RESULTS: This case-control study was conducted in 101 ALS patients and 119 healthy individuals. Genotyping was performed by Polymerase Chain Reaction – Restriction Fragment Length Polymorphism (PCR-RFLP). The statistical analysis was carried out using the RStudio® and SNPStats© software’s. Analysis of genetic inheritance models was performed by logistic regression. Our findings demonstrated a strong association between VEGF- A rs28357093 and ALS in all genetic inheritance models, with a 9-fold increased risk for A/C – C/C genotypes (95%CI = 3.70-21.88; p < 0.001).
CONCLUSIONS: The mutant allele was more frequent in ALS patients (p < 0.001) and this finding could be associated with ALS risk. This first study from the Brazilian central population was conducted to provide new insight into the pathogenesis of ALS.
