Genetic variations in P-selectin glycoprotein ligand-1 (SELPLG) and P-selectin (SELP) were studied for multiple sclerosis (MS) risk. No significant association was found for the investigated single-nucleotide polymorphisms (SNPs) in either Italian or UK populations.

Area of Science:

  • Immunogenetics
  • Neuroimmunology
  • Molecular Biology

Background:

  • P-Selectin (SELP) and P-selectin glycoprotein ligand-1 (SELPLG) form a complex crucial for lymphocyte recruitment in multiple sclerosis (MS) pathogenesis.
  • Genetic variations in these molecules may influence MS susceptibility.

Purpose of the Study:

  • To investigate the association between genetic polymorphisms in SELPLG and SELP and susceptibility to multiple sclerosis (MS).

Main Methods:

  • Genotyping of three single-nucleotide polymorphisms (SNPs): SELPLG Met62Ile, SELP C-2123G, and SELP Thr715Pro.
  • Comparison of allele frequencies between 214 Italian MS patients and 220 Italian controls.
  • Replication analysis of the SELPLG Met62Ile SNP in 938 UK trio families.

Main Results:

  • No significant differences in SELP C-2123G and SELP Thr715Pro SNPs between Italian patients and controls.
  • A decreased frequency of the SELPLG Met62Ile SNP was observed in Italian MS patients compared to controls (P = 0.025).
  • The SELPLG Met62Ile SNP showed no evidence of association with MS susceptibility in the larger UK cohort.

Conclusions:

  • The investigated SNPs in SELPLG and SELP are not associated with MS susceptibility in the studied populations.
  • While this study did not find a conclusive link, further research on other genetic variations in SELPLG and SELP is warranted to fully exclude their role as MS risk factors.
