Tech Newsletter #2: More loci, more assistance, more details

Presented: DRB3/4/5, DQA1, DPA1, MICA and MICB

We are happy to announce, that DRB3/4/5, DQA1, DPA1, MICA and MICB are now supported as peptide sources. Mismatches between patient and donor occurring on these loci will be included in the PIRCHE analysis. This allows us to predict foreign allo-peptides even for 5- or 6-loci matched cases. This update is now available to all PIRCHE csv modules.


Where is it from?

The solid organ PIRCHE modules are now showing you the PIRCHE score per locus, per presenting molecule and even per mismatch. This allowed us to consider identical peptides from different mismatches as duplicates, giving more precise scores.

 


All on board the tour bus

You don’t know what modules there are? Now you’ll find previews for all available PIRCHE modules in the sidebar. But if you like, we can also show you around: Take the tour and see what’s there and how it’s used.

 

 


Serologic or molecular

Our extrapolation of low resolution typings now allows you to select between serologic and molecular typing inputs. This improves accuracy of imputation and therefore refines overall prediction.
