Abstract: In order to select compatible human leucocytes antigens (HLA) donors for bone marrow graft, all the members of 76 families were typed by serology for HLA classI (A and B locus) and classII (DR, DQ locus) by polymerase chain-reaction–sequence-specific primes (PCR–SSP). The HLA typing interpretation revealed the existence of crossing-over in major histocompatibility (CMH) regions for two families, AB and AT, with aplastic bone marrow. The study of crossing-over site has needed the genotyping of seven short tandem repeat (STR) markers located on the short arm of chromosome6 (D6S291, D6S273, TNFa, C1.2.C, C3.2.11, D6S265, D6S276), using ABIPrism310 sequencer. HLA and STR Haplotypic analysis enabled us to confirm the crossing-over between locusB and DR in ABfamily and between locusA and B in ATfamily. Based in this study, we recommend to be careful in the interpretation of the results of HLA typing between donors and recipients of bone marrow. Complementary investigations should be accomplished for studying genetic abnormalities, which would be involved in this pathology. [Copyright &y& Elsevier]
