Welcome to the official website of the 17th International HLA and Immunogenetics Workshop (IHIWS). The tradition of the International HLA and Immunogenetics Workshop is strong and compelling. Sixteen prior workshops have provided the opportunity and momentum for major technological and scientific progress.
The 17th Workshop promises to further advance the continued international collaboration in research in HLA and Immunogenetics projects. The major goals are to define HLA and KIR genomics, map serologic epitopes using NGS and single antigen bead technologies, and develop robust research and clinical informatics tools for HLA and KIR.
We hope you will join us at the 17th International HLA and Immunogenetics Workshop to be held at the Asilomar Conference Grounds in Pacific Grove, California, September 6 – 10, 2017. This will be followed by the American Society of Histocompatibility and Immunogenetics (ASHI) 44th Annual Meeting September 11 – 15, 2017 in San Francisco, California.
Please set aside these important dates in 2017. We hope to see you in the San Francisco Bay Area during this time. Learn how you can participate, and keep up with the latest developments by signing up for email updates.

About the Workshop / How to Participate
Components & Projects
The 17th IHIWS will study HLA and KIR genomics, define full length MHC sequences, map serologic epitopes and develop robust informatics for HLA and KIR research through the use of NGS, single antigen beads (SAB) and flow cytometry.
The 17th IHIWS projects will fall under the following components:

The HLA genes are the most polymorphic loci in the human genome; over 12,000 genetic variants (alleles) have been identified at 19 HLA genes, with some individual genes displaying several thousand alleles. The allelic and structural variation that characterizes these genes pose extreme challenges for routine genotyping of these genetic loci; this variation cannot be characterized by a few SNPs, and the high level of polymorphism confounds de novo sequence assembly efforts. Until recently, HLA genotyping has been accomplished using a variety of PCR-based approaches involving sequence-specific oligonucleotide probe (SSOP) hybridization and/or Sanger sequencing of 400-600 base pair amplicons. These... Read More

The ultimate goal of the 17th International HLA and Immunogenetics Workshop (IHIW) is to advance the fields of Histocompatibility and Immunogenetics (H & I) research through the application of Next-Generation Sequencing (NGS) technologies for HLA and KIR genotyping, and to advance the development of NGS technologies tailored to meet the needs of the H & I community.
In 2014, we initiated an international multi-center pilot study in order to assess the performance of various NGS protocols, platforms,... Read More
The T cell receptor is the natural receptor of the HLA-peptide complex and interacts directly with MHC molecules, notably their CDR regions. The goal of this project will be to combine analysis of TCR and HLA in the context of disease, vaccination/immune alterations and populations. We would expect samples to be CD4 or CD8 T cells and to have full HLA class I and class II typing by NGS.
Required NGS HLA loci: HLA-A, B, C, DRB1, DRB3/4/5, DQB, HLA-DQA, DPA, DPB
Optional NGS HLA Loci: MICA, MICB
The Human Leucocyte Antigen (HLA) is one of the most polymorphic gene systems present in the human genome and due to this high polymorphism, the golden standard for typing at the allele level has been and still is sequence based typing. Since sequencing strategies have mainly focused on identification of the peptide binding groove, therefore the majority of HLA alleles lack full length sequence information.
The goal of this project is to extend the sequences of as many incompletely covered HLA alleles as possible by full length unambiguous Sanger Sequencing. Although NGS approaches are currently implemented in several laboratories, many... Read More
17th IHIWS Vendor Summit
SEPTEMBER 25, 2016
ST. LOUIS, MO
During this Summit, we had presentations from Kazutoyo Osoegawa PhD, Stanford HIDPL, who described the Data entry experience from various participants into the IHIWS database, demonstrating the need for standarized reporting.
We also heard from Steve Mack PhD, CHORI, whose presentation provided an overview of the workshop and specifically the database, highlighting the need to have uniform Data content and why all NGS data and meta-data should be compatible and comparableallowing all formats to be equally interpretable during analysis. Steve described the concept of Minimum Information for Reporting Immunogenomic NGS Genotyping (MIRING) and why it is essential to analysis to be performed on the data collected.
Last, we heard from Bob Milius PhD, Bioinformatics Research NMDP®/Be The Match®. Bob presentation focused on MIRING & HML reporting as well as XML schemas. In a second presentation, Bob described Genome Sequence Coordinates, advantages and disadvantages of One-Based Vs. Zero-Based systems and matching SequenceBlock to the reference sequence.
