Some of these genes are critical for immune response, in the case of CD30L probably protective in terms of GVHD.

The C-C chemokine receptor type 5 (CCR5) belongs to the super family of the seven-transmembrane G-protein coupled receptors (GPCRs) [1].

Hence, 74 mutations have been described in this gene up to date including the intensively studied 32 base pair deletion (CCR5-delta32) that introduces a premature stop-codon into the CCR5 locus [5–7].

Epidemiologic studies have shown that the mutation occurs most frequently in the Caucasian population with up to 10-20% heterozygous and 1% homozygous carriers, while it can not be found in the Asian, Middle East, African, and the American Indian population [8].

CCR5 has gained prominence as a cofactor for HIV-1 entry.Although there are advances in the treatment of GVHD, this inflammatory immunoreaction is still responsible for 15% of treatment related mortality [22].Therefore, understanding and manipulating the mechanisms of GVHD is of important scientific and clinical impact.It interacts with chemokines that mediate the trafficking and function of memory/effector T-lymphocytes, macrophages, and immature dendritic cells towards sites of inflammation [2].When bound by their chemokine ligands, these receptors can be internalized, impairing the subsequent ability to bind their ligands.

For HSCT, testing for at least five HLA genes is required before declaring that donor and recipient are HLA-concordant.
