The understanding of gene regulation and the role of polymorphic sites on gene function may permit an individualized approach for the future use of HLA-G for therapeutic purposes.
The origin and spread of the HFE-C282Y haemochromatosis mutation

The evidence about HFE C282Y frequencies, extended haplotypes involving HLA-A and -B alleles, the validity of calculations of mutation age, selective advantage and current views on the relative importance of “demic-diffusion” and “adoption-diffusions” in the neolithic transition in Europe and since then are examined.
HLA alleles in isolated populations from North Spain: origin of the Basques and the ancient Iberians.

HLA-A, -B, -DRB1, -DQA1 and -DQB1 alleles have been studied in three relatively isolated populations of northern Spain and compared with neighbouring ones and other Mediterraneans by using neighbour-joining dendrograms and plane genetic distances.
Rapid Radiation of Canaries (Genus Serinus)

Mitochondrial cytochrome b DNA from 20 out of 37 extant canaries (genus Serinus) has been sequenced from living specimens photographed around the world and suggests a remarkably rapid radiation when compared to other passerine (songbird) genera radiations.
A new HLA-G allele (HLA-G*0105N) and its distribution in the Spanish population
- M. B. Suárez, P. Morales, A. Arnaiz-Villena
- BiologyImmunogenetics
- 1997
In the present study a new HLA-G subtype is described in the Spanish population; this allele shows linkage disequilibrium with the HLA A30-B13 haplotype and bears a nucleotide deletion either in the third position of codon 129 or the first ofcodon 130.

Genetic distances are closer between Greeks and Ethiopian/ sub-Saharan groups than to any other Mediterranean group and Greeks cluster with Ethiopians/sub-Saharans in both neighbour joining dendrograms and correspondence analyses.

A Point Mutation in a Domain of Gamma Interferon Receptor 1 Provokes Severe Immunodeficiency

- 1 January 2001
The findings suggest that a point mutation may be fatal when it affects functionally important domains of the receptor and that the severity is not directly related to a lack of IFN-γ receptor expression.
HLA class I allele distribution of a Hong Kong Chinese population based on high-resolution PCR-SSOP typing.

Knowing which alleles do/do not occur in this population will aid in the distinction of ambiguities which result from the use of many of the typing kits available, as well as influence the search strategy and the ongoing compilation of new donors to the registry.
Estrildinae Finches (Aves, Passeriformes) from Africa, South Asia and Australia: a Molecular Phylogeographic Study

The results support that Estrildids are a monophyletic group with polytomies that may have started evolving by Middle Miocene Epoch (about 16, 5 million years ago), and suggest that the whole Estrialdids radiation might have originated around India.
