Description

Registry Version: 2.0

This website is designed for research purposes only. The contents are not intended for making clinical decisions regarding donor selection or patient care.

There are five separate databases: ABC, DRB1/3/4/5, DQB + DQA, DPB + DPA and MICA.

Their layouts display:

• 1 Eplet names.
• 2 ElliPro scores - derived from the ElliPro epitope predictor program, these scores may be useful in determining eplet immunogenicity.
• 3 Polymorphic residues - the amino acid positions and specific residues that describe the eplet.
• 4 Frequency - links to www.allelefrequencies.net website for eplet frequencies in different populations.
• 5 Antibody reactivity - “Yes” links to antibody reactivity reports for antibody-verified eplets; information for any eplet pairs, i.e, eplet variants in combination with distinct amino acid configurations shared by reactive alleles, is shown below information for the single eplet.
• 6 Struct epitope - information about corresponding “structural” epitopes; the links provide amino acid residues within a 15 Ångstrom radius that may help to explain antibodies that react only with a subgroup of epitope-carrying alleles because they require the eplet to be paired with other residue configurations.
• 7 Luminex alleles - eplet carrying alleles in commonly used Luminex panels
• 8 All alleles - listing of all alleles that share an eplet

Each eplet has its own row, and eplets are sorted according to their amino acid sequence positions. Each database has search options to identify repertoires of antibody-verified eplets on selected alleles and eplets that are mismatched for a given HLA type. A new feature is the “EpiPedia of HLA”, which summarizes the experimental evidence for each antibody-verified HLA eplet. Click here to download the PDF.
