Background: Apolipoprotein E protein is a family of apolipoproteins that play an important role in lipid metabolism. Apolipoprotein E genotype and single-nucleotide polymorphisms of genes are known to induce neurodegenerative diseases and cardiovascular diseases. Recently, it has been reported that apolipoprotein E is related to Hansen's disease by regulating genes related to lipid metabolism.
Objective: In this study, we investigated that relationship of apolipoprotein E genotype with leprosy type and single-nucleotide polymorphism in korean persons affected by leprosy.
Methods: The Apolipoprotein E genotype was confirmed using the polymerase chain reaction from korean persons affected by leprosy. Real-time polymerase chain reaction using probes confirmed the rs405509 and rs439401 of Apolipoprotein E. The identified genotype was cross-analyzed with each single-nucleotide polymorphism results and leprosy type by chi-squared test.
Results: The distribution of apolipoprotein E genotypes was E3/E3 76.7%, E3/E4 17.4%, E2/E2 2.3%, E2/E3 2.3%, E2/E4 1.2% were in order. The frequencies of the apolipoprotein E allele were identified in the order of ε2 4.1%, ε3 86.6%, and ε4 9.3%. By type of leprosy, ε2 allele increased 2.2 times in multibacillary than pauacibacillary(4.8% vs 2.2%), and ε4 allele decreased 2.8 times in multibacillary than pauacibacillary(6.3% vs 17.4%). ApoE genotype was cross-analyzed with rs405509·rs439401, and there was a statistically significant association.
Conclusion: Apolipoprotein E genotype is associated with leprosy types in korean persons affected by leprosy. The research for apolipoprotein E gene is thought to be helpful in basic research on the pathogenesis of leprosy.who underwent surgery.
