Variable number tandem repeat (VNTR) polymorphisms of the human neonatal IgG Fc receptor α-chain gene (FCGRT) are known to influence the expression levels of FCGRT and IgG in serum. Monkeys are considered to be a relevant biological model for studying the effects of immunobiological drugs. The study determined the functional VNTR polymorphisms of the FCGRT gene in 109 male rhesus macaques from the nursery of the Kurchatov Complex of Medical Primatology. PCR amplification of samples was carried out followed by electrophoretic separation of DNA fragments in a 2% agarose gel. Individual DNA amplification products were sequenced (according to Sanger system) in forward and reverse directions to confirm the specificity. The genotyping showed that the VNTR polymorphism of the FCGRT gene in the studied population of rhesus macaques is presented by 9 variants. The frequency of the VNTR5 allele associated with lower IgG levels was 14.2%, and the most common one was the VNTR7 allele (25.2%). We also identified alleles that have not been previously reported: VNTR3, VNTR4, VNTR6, VNTR8, and VNTR9. The study allows to consider rhesus macaques as a potential model for studying the immunological response depending on the genetic VNTR variant of FCGRT. [ABSTRACT FROM AUTHOR] |
