ABCB1-Gen-Polymorphismus in einer polnischen Kohorte ist mit Risiko für bullöses Pemphigoid assoziiert

Area of Science:

• Genetics
• Immunodermatology
• Pharmacogenomics

Background:

• ABCB1 gene polymorphisms can affect xenobiotic concentrations, potentially contributing to autoimmune diseases like bullous pemphigoid (BP).
• Investigating the association between ABCB1 gene variants and BP risk is crucial for understanding disease pathogenesis.

Purpose of the Study:

• To examine the association of ABCB1 gene C3435T and G2677T/A polymorphisms with the risk of developing bullous pemphigoid (BP) in a Polish cohort.

Main Methods:

• The study included 71 BP patients and 156 healthy controls.
• C3435T polymorphism was analyzed using PCR-RFLP.
• G2677T/A polymorphism was determined via allele-specific PCR.

Main Results:

• No significant correlation was found between the C3435T polymorphism and BP risk.
• The G2677T/A polymorphism showed a significant association with BP risk.
• Individuals with the 2677TA genotype had over a fivefold increased risk (OR=5.52), and 2677TT genotype carriers had more than double the risk (OR=2.40).
• The 2677T allele also showed an increased risk (OR=2.40).
• The 2677GG genotype and 2677G allele were more prevalent in controls, suggesting a protective role (OR<1.0).

Conclusions:

• The G2677T/A polymorphism in the ABCB1 gene may influence the risk of developing bullous pemphigoid.
• The 2677G allele might confer a protective effect against BP.
