- Background: Immunoglobulin G subclass deficiencies (IgGsd) are associated with recurrent respiratory tract infections. Immunoglobulin substitution therapy may be needed to prevent chronic lung tissue damage but tools for identifying the patients that will benefit from this treatment are still insufficient. Some Fc gamma R polymorphisms seem to predispose for an increased risk for infections. In this study we wanted to evaluate if the Fc gamma R-profile differs between individuals with IgGsd and a control population. Methods: Single nucleotide polymorphisms (SNPs) of Fc gamma RIIa, Fc gamma RIIIa and Fc gamma RIIc in 36 IgGsd patients and 192 controls with similar sex and geographical distribution were analyzed by TaqMan allelic discrimination assay or Sanger sequencing. Results: In the IgGsd-group, homozygous frequency for Fc gamma RIIa-R/R131 (low-binding capacity isoform) was higher (p = .03) as well as for non-classical Fc gamma RIIc-ORF (p = .03) and classical Fc gamma RIIc-ORF tended (p = .07) to be more common compared to the controls. There was no difference between the groups regarding Fc gamma RIIIa. Conclusion: The gene for classical Fc gamma RIIc-ORF tended to be more frequent in individuals with immunoglobulin G subclass deficiency and the genes for non-classical Fc gamma RIIc-ORF as well as low-binding capacity receptor Fc gamma RIIa-R/R131 were more frequent. Further studies on the Fc gamma R polymorphisms may pave way for identifying individuals that will benefit from immunoglobulin substitution.
