Mannose-binding lectin gene (MBL-2) polymorphism in oral lichen planus

Area of Science:

• Immunogenetics
• Oral Medicine
• Molecular Biology

Background:

• Tumor Necrosis Factor-alpha (TNF-α) is implicated in oral lichen planus (OLP) pathogenesis.
• Mannose-binding lectin (MBL) gene polymorphism may influence TNF-α production.
• Understanding MBL's role could offer insights into OLP etiology.

Purpose of the Study:

• To evaluate the association between MBL-2 gene genetic diversity and oral lichen planus (OLP).
• To determine if MBL gene variants are relevant in the development of OLP.

Main Methods:

• Real-time PCR was used to amplify the MBL-2 gene in 45 OLP patients and 45 healthy controls.
• Genotype and allele frequencies of MBL-2 were analyzed.
• Statistical analysis was performed to compare OLP patients and healthy volunteers.

Main Results:

• No statistically significant differences were observed in MBL-2 genotype frequencies between OLP patients and controls (p = 0.546).
• Allele frequencies for MBL-2 also showed no significant variation between the groups (p = 0.497).
• The distribution of A/A, A/0, and 0/0 genotypes did not differ significantly.

Conclusions:

• The study found no significant association between MBL-2 gene polymorphism and oral lichen planus.
• Genetic diversity of MBL does not appear to be a risk factor for OLP in the studied population.
• Further research may explore other genetic or environmental factors in OLP pathogenesis.
