Scientists now have a better understanding of the incredible genetic diversity of the HLA region which currently consists of over 28,000 different alleles. In an ideal world, HLA typing technologies should be flexible enough to provide different levels of resolution and additional loci as and when their genotyping is required. Today’s HLA typing scientists are faced with an often overwhelming array of methods for HLA typing. 2021-03-12 · The T1DGC panel contains 5868 SNPs (genotyped using Illumina Immunochip) and 4-digit resolution HLA typing data of classical HLA genes (HLA-A, HLA-B, and HLA-C for class I; HLA-DPA1, HLA-DPB1, HLA Presented at ASHI 2018 by Hiroko Shike, MD, D(ABHI) | Penn State Hershey Medical Center HLA testing is challenging due to its high polymorphic nature and high levels of sequence homology between the loci.

The principle of these assays involves the hybridization of reverse sequence-specific oligonucleotide probes each attached to a unique colour coded microsphere to identify HLA class I and class II alleles.

Overview on HLA and DNA typing methods @ Annia Ferrer , María E Fernández, Marcelo Nazabal Genomics Department, Center for Genetic Engineering and Biotechnology (CIGB)

Typing of HLA genes differs from most molecular testing as, rather than evaluating differences from an accepted "wild-type" gene, it must distinguish between thousands of similar, but distinct alleles. DNA based HLA typing is fast replacing conventional Microlymphocytotoxicity based method, which has been regarded as the gold standard. Many laboratories in Mumbai have already switched over to HLA Typing Methods, Techniques and Results.

HLA typing is a kind of genetic test used to identify certain individual variations in a person’s immune system. The process is critical for identifying which people can safely donate bone marrow, cord blood, or an organ to a person who needs a transplant. HLA stands for human leukocyte antigen, but it is almost always referred to as HLA. The methods most widely used for HLA typing and clinical histocompatibility testing are based on the recognition of locus-specific polymorphisms in genomic DNA by sequence-specific primers (SSP) or by hybridization of sequence-specific oligonucleotide probes (SSOP) with DNA that has been selectively amplified by the PCR. Abstract. Histocompatibility testing is a specialized area of clinical laboratory science with particular relevance to transplant pro– grams.
