This has been possible largely because of the identification of HLA as the human major histocompatibility system and the application of new technologies for improving the accuracy of HLA typing and matching.

The aim of this study was to provide a comprehensive immunological analysis of the complement system status, autoantibody signatures and HLA profile in BSS. Therefore, the development of a 500-bead system associated with a LABScan 3D has allowed to reduce or solve many ambiguities through a powerful software able to differentiate the different probes and analyze the reaction pattern with reliability, Complete sequence and genemap of a human major histocompatibility complex, The LABType(®) SSO (One Lambda, Inc) and Gen-Probe LIFECODES HLA-SSO HLA Typing tests are rapid and efficient assays for determining human leukocyte antigens (HLAs). A single PCR reaction is used for each HLA locus. Many anti-HLA antibodies are specific for epitopes rather than for HLA antigens and the knowledge of unacceptable epitopes allows to reduce the number of mismatched antigens. Methods Mol Biol. The assignment of the HLA typing is based on positive and negative probe reactions compared with published HLA gene sequences.

The influence of nongenetic factors on the tolerability of HLA mismatching has recently become evident, demonstrating a need for the integration of both genetic and nongenetic variables in donor selection. © 2020 Springer Nature Switzerland AG.

Mismatching at HLA-DP or -DQ loci and donor factors other than HLA type were not associated with survival. Mismatching at 2 or more loci compounded the risk.
In 2014, the time for testing was shorter (141 vs 181 days on average), the number of test repetitions was lower (in particular for HLA-A locus, p = 0.026), and the cost reduced (240.7 vs 395.6 euros per unit on average) compared to 2013, demonstrating that Luminex xMAP technology is superior to the previous approach. High definition of both class I and II HLA loci at time of listing is a way to improve the attractiveness of cord blood bank inventories, reducing the time for donor search and procurement and simplifying donor choice, in particular, for patients of non-European heritage.

C3 hypocomplementemia and the presence of C3 nephritic factor (C3NeF), an autoantibody causing complement system over-activation, are common features among most patients affected by Barraquer-Simons syndrome (BSS), an acquired form of partial lipodystrophy.

Here, we reported a case with HLA-B allele dropout by Luminex technology.
