A novel HLA-G allele, HLA-G*010111, in the Brazilian population.

The human leukocyte antigen-G (HLA-G) gene plays an important role in pregnancy and is related to negative signals for natural killer cells and T lymphocytes. Herein a new HLA-G allele (HLA-G*010111) is described in the Brazilian population--one of the most heterogeneous populations in the world. The new allele is associated with the 14-bp deletion at exon 8 and is similar to the HLA-G*01010105 allele, except for a C to G transversion at codon 117 in exon 3.
