Seven single nucleotide substitutions in human Fcγ receptor IIB gene

Abstract

Variation screening for the immunoglobulin G Fc receptor IIB (Fc(gamma)RIIB) gene was performed with the genomic DNA from 100 healthy Japanese subjects. We identified 3 non-synonymous and 2 synonymous substitutions and 2 single-nucleotide polymorphisms in an intron region. These substitutions were found to be located in the ligand-binding domain and the intron, which might alter the function of Fc(gamma)RIIb.
