IL27 T4730C Polymorphism and Serology in Multiple Sclerosis: A Pilot Study

Area of Science:

• Neuroimmunology
• Genetics
• Molecular Biology

Background:

• Multiple sclerosis (MS) is a debilitating neurological disease affecting young adults.
• The interleukin 27 (IL27) gene promoter polymorphism (T4730C, rs181206) may influence cytokine production and MS susceptibility.

Purpose of the Study:

• To investigate the association between the IL27 T4730C polymorphism and MS risk.
• To evaluate serum IL27 levels in relation to MS and the T4730C polymorphism.

Main Methods:

• A case-control study involving 51 MS patients and 31 healthy controls.
• Genotyping of the IL27 T4730C polymorphism using polymerase chain reaction-restriction fragment length polymorphism.
• Quantification of serum IL27 levels via enzyme-linked immunosorbent assay.

Main Results:

• Carriers of the T4730C polymorphism exhibited a 6-fold increased risk of MS.
• Increased frequencies of the TC heterozygous genotype and C allele were observed in MS patients.
• MS patients had significantly lower serum IL27 levels compared to controls.
• Both IL27 T4730C polymorphism and smoking were identified as independent risk factors for MS.

Conclusions:

• The IL27 T4730C gene polymorphism is associated with an increased risk of multiple sclerosis.
• Lower serum IL27 levels may play a role in MS pathogenesis.
• This study suggests a link between IL27 genetic variations, cytokine levels, and MS risk in a Romanian population.
