TNFAIP3 mutation

Together, we demonstrate variable clonal B-cell dynamics in LPL/WM patients developing DLBCL, and the occurrence of clonally unrelated DLBCL in about one-quarter of LPL/WM patients. Moreover, we identified commonly mutated genes upon DLBCL transformation, which together with preserved mutations already present in LPL characterize the mutational landscape of DLBCL occurrences in LPL/WM patients.

MYD88 L265P and to lesser extent TNFAIP3 mutations are major mutations in ABC- DLBCL and may be predictive factors for poor OS in ABC- DLBCL patients.

Detection of acquired BTK and PLCG2 mutations in ctDNA while on therapy is feasible and may herald clinical disease progression. This trial was registered at https://anzctr.org.au/ as ACTRN12619000024145.

TNFAIP3 mutation mainly occurs in adult T-ALL patients, and it was associated with adverse clinical outcomes for T-ALL patients; thus, it might be a biomarker for prognostic stratification.

A better understanding of the composition of TIME in EBV-LELCC is critical for predicting the clinical outcomes of ICB treatment.

Fig1E In support of this, SPADE clustering analysis identified three clusters including T FH , T reg and T EM cells. Conclusion We have identified three molecular clusters in IgM monoclonal gammopathies with distinct clinical, proteomic, metabolomic and immune features, suggesting a potential biologic classification that may have therapeutic implications.

An exploratory analysis of the ibrutinib-treated rrMZL study showed mutations in genes regulating NF-kB signalling pathway: TNFAIP3 ( A20 ) and MYD88 predicted response, whereas KMT2D ( MLL2 ) and CARD11 were associated with primary resistance. Conclusion Mutations in genes associated with the NFkB pathway present at baseline are predictive of response to zanubrutinib in rrMZL patients. Detection of acquired BTK and PLCy2 mutations on therapy is feasible and may herald clinical disease progression.

Our study observed comprehensive CNVs in PLELC patients which is a unique molecular feature compared with other NSCLC subtypes and EBV-positive NPC. Higher TMB level and amplifications of B2M in PLELC patients may be used as potential biomarkers to indicate better treatment responses to ICIs.

Those metabolites had intermediate levels in C3. In conclusion, we identified three molecular clusters with distinct clinical, proteomic and metabolomic features, suggesting a potential biologic classification that may have therapeutic implications.

Conversely, while EBV-negative MALT lymphomas typically show mutational abnormalities in the NF-κB pathway, other than the 1 TNFAIP3-mutated case, no other NF-κB pathway mutations were identified in the EBV-positive cases. EBV-positive MALT lymphomas often have either mutations or copy number abnormalities in IRF family or interacting genes, suggesting that this pathway may play a role in these lymphomas.

Significance : We report that simultaneous disruption of essential regulators XPO1 and A20 in murine B cells encourages development of irregular B and T cell populations, and can stimulate a progressive CLL-like or T cell leukemia-like expansion. Continued investigation with these models can further our understanding of the relationship between overall immune function and these critical regulatory molecules, and can provide considerable insight to identifying pathways for selective targeting as a personalized therapy in several high-risk cancer types.

There were no significant factors for spontaneous regression or response rates according to the presence of mutations. Overall, OIIA-LPDs, especially DLBCL-types, showed favourable prognoses.

To the best of our knowledge, we for the first time describe that TNFAIP3 mutations in non-CDS regions are associated with favorable OS for TCL patients, which might be a potential biomarker for the prognostic stratification of Chinese TCL patients.

Patients with STAT3 mutation, inclusive of those with TET2 co-mutation, had lower hematocrit (HCT), hemoglobin (HGB), and absolute neutrophil count (ANC) compared to STAT3 wild-type patients (Welch's t-test, p<=0.015). We present the discovery of TET2 mutations in chronic NK-LGL leukemia and evidence that it identifies a unique molecular subtype.

The onset of HA20 in patients with the ZnF domain disruption is earlier than patients with the OTU domain disruption. Compared to the OTU domain, the ZnF domain may be more closely related to musculoskeletal disorders.

Poly-EBV-L cases presented a distinct mutational profile including STAT3 mutations and a significantly lower coding-mutation load in comparison to EBV-negative GZL. Our study highlights characteristic mutational patterns in GZL associated with presentation in the thymic niche suggesting a common cell of origin with disease evolution overlapping with related anterior mediastinal lymphomas.

In conclusion, 80% of OA-MZL display mutations of either NK-κB compounds or chromatin modifiers. Lymphoid lesions of the OA bearing NF-κB compound mutations and/or mutations of acetyltransferase-encoding genes highly likely represent lymphomas.
