Background: Hepatocyte Growth Factor (HGF) was shown to play a key role in synaptogenesis, survival, maturation, and reconstruction of neuron cells and was shown to be implicated in Autism Spectrum Disorder (ASD).
Objectives: Assessing the relationship between HGF (rs3735520) gene polymorphism and its circulating levels in ASD.
Materials & Methods: A total of 140 ASD patients and 120 children healthy controls referred to Shahid Rajaei Hospital, Mazandaran, Iran from September 2017 to January 2019 were enrolled in the study. Genomic DNA was extracted from blood samples, HGF polymorphism was determined
by polymerase chain reaction-restriction fragment length polymorphism and HGF serum concentration was measured by enzyme-linked immunosorbent assay. Statistical analysis was done by ANOVA and the Chi-square test, using χ² in MedCalc statistical software ver. 12.1.4.
Results: Genotype frequencies of CC, CT, and TT in the ASD group were 25.71%, 52.86%, and 21.43%, and in controls were 26.67%, 68.33%, and 5%, respectively (P=0003) and C and T alleles frequencies in patients were 53% and 47% and in controls were 61% and 39%, respectively (P=0.046). Moreover, the Mean±SD serum HGF levels in the controls and ASD patients were 363.33±118.44 and 219.95±73.61 pg/mL, respectively (P=0.009). Furthermore, ASD patients carrying TT genotype had lower serum HGF levels than CT and TT carriers (CC, CT, and TT Mean±SD serum levels were 271.88±30.47, 217.77±33.59 and 156.33±22.72 pg/mL, respectively).
Conclusion: There was a significant relationship between HGF gene polymorphism and its serum levels with ASD in an Iranian population. We also suggest that TT genotype may be associated with a decrease in HGF circulation levels in ASD.
