    Abstract

    Human leukocyte antigen-G (HLA-G) is a non-classical HLA class Ib molecule shown to exhibit immunomodulatory function in a wide range of immune-based disorders. A number of functional HLA-G gene polymorphisms have been identified, including a 14-bp insertion/deletion polymorphism in exon 8 of the 3 untranslated region of the HLA-G gene, which has been associated with HLA-G mRNA stability. Moreover, studies show that homozygosity for the 14-bp insertion/deletion polymorphism is associated with lower HLA-G mRNA and protein levels and unique alternative splicing patterns. Here, we introduce a quick and reliable method to screen for the HLA-G 14-bp insertion/deletion polymorphism using an optimized real-time polymerase chain reaction protocol. The genotyping assay has been validated by comparison with conventional methods. As results can be obtained within a few hours, the assay will have a potential for clinical use.
