To evaluate the association between human leukocyte antigen (HLA) alleles and native asparaginase hypersensitivity (AH) in children with acute lymphoblastic leukemia (ALL) who received Dana-Farber Cancer Institute treatment protocols. , and alleles were retrieved from available whole exome sequencing data of a subset of childhood ALL patients from Quebec ALL cohort and analyzed for an association with AH. PCR assay was developed to analyze associated alleles in the entire discovery and replication cohorts. Two alleles in linkage disequilibrium ( and ) were associated with AH. Additional analyses, performed to distinguish between haplotypes with and without allele, showed that the association was dependent on the presence of . This study confirms the implication of , and alleles in developing AH in childhood ALL.

Circulating tumor DNA (ctDNA) detection can predict clinical risk in early-stage tumors. However, clinical applications are constrained by the sensitivity of clinically validated ctDNA detection approaches. NeXT Personal is a whole-genome-based, tumor-informed platform that has been analytically validated for ultrasensitive ctDNA detection at 1-3 ppm of ctDNA with 99.

Tumor-specific HLA class I expression is required for cytotoxic T-cell elimination of cancer cells expressing tumor-associated or neo-antigens. Cancers downregulate antigen presentation to avoid adaptive immunity. The highly polymorphic nature of the genes encoding these proteins, coupled with quaternary-structure changes after formalin fixation, complicate detection by immunohistochemistry.

Background: This study aimed to investigate the association between the Fc-gamma receptor IIIA (FCGR3A) 158 polymorphism and clinical outcomes in kidney transplantation (KTx) patients. Specifically, we focused on late-onset neutropenia (LON) in ABO-incompatible (ABOi) or HLA-incompatible (HLAi) KTx recipients who underwent rituximab (RTx) desensitization therapy.
Methods: FCGR3A 158F/V polymorphisms were identified in 85 ABOi or HLAi KTx recipients who underwent RTx desensitization at our institution between April 2008 and October 2021.

Background And Aims: Short courses of intravenous (iv) methylprednisolone (MP) can cause drug induced liver injury (DILI). The aim of this study was to assess the clinical features and HLA associations of MP-related DILI enrolled in the US DILI Network (DILIN).
Methods: DILIN cases with MP as a suspected drug were reviewed.
The Role of Vimentin Peptide Citrullination in the Structure and Dynamics of HLA-DRB1 Rheumatoid Arthritis Risk-Associated Alleles.

Citrullination, a post-translational modification (PTM), plays a critical role in rheumatoid arthritis (RA) by triggering immune responses to citrullinated self-antigens. Some HLA-DRB1 genes encode molecules with the shared epitope (QKRAA/QRRAA) sequence in the peptide-binding groove which preferentially presents citrulline-modified peptides, like vimentin, that intensifies the immune response in RA. In this study, we used computational approaches to evaluate intermolecular interactions between vimentin peptide-ligands (with/without PTM) and HLA-DRB1 alleles associated with a significantly increased risk for RA development.
