Restricted immunoglobulin constant heavy G chain genes in primary immunodeficiencies.

Abstract
Some primary immunodeficiencies (PIDs) express low serum levels of antibodies. The constant heavy G chain (IGHG) genes, also representing Fc domains of gamma3, gamma1 and gamma2 on chromosome 14q32.3, genotyped by the alternative IgG subclass allotypes, found in four fixed IGHG haplotypes, designating four B cell variants, were identified by a competitive ELISA and double immunodiffusion. IGHG genes were hypothesized to contribute to the development of PIDs. From 235 Caucasian patients, the homozygous IGHGbf-n/bf-n diplotype (B(bf-n)/B(bf-n) cells) dominated significantly in 43 IgG2 deficiency (OR 6.0), 32 common variable immunodeficiency (OR 4.6) and 22 Ataxia telangiectasia (OR 3.0) and the IGHGga-n/ga-n diplotype (B(ga-n)/B(ga-n) cells)...

Restricted IGHG genes, restricted IgG allotypes (Fc domains) and restricted B cells are significant in PIDs for diagnosis, treatment and pathogenetic mechanisms. (Less)
