Anti-myelin IgGs occur in the cerebrospinal fluid (CSF) and serum of multiple sclerosis (MS) patients, and can induce inflammatory effector functions in leukocytes by crosslinking IgG receptors (FcgammaR).

The efficiency of FcgammaR-mediated inflammatory processes is affected by functional polymorphisms of three Fcgamma receptors (FcgammaRIIa, FcgammaRIIIa, FcgammaRIIIb).

The relevance of FcgammaR polymorphisms in MS was evaluated by studying the distribution of FcgammaRIIa, FcgammaRIIIa and FcgammaRIIIb genotypes in 432 MS patients and 515 healthy controls.

No significant differences were found between MS patients and controls, or between subgroups of patients.

We conclude that Fcgamma receptor polymorphisms influence neither susceptibility nor clinical disease course of MS.
