JAK1 mutations are not frequent events in adult T-ALL: a GRAALL study

pi 6 mutations / deletions are not frequent events in prostate

Pediatric-inspired intensified therapy of adult T-ALL reveals the favorable outcome of NOTCH1/FBXW7 mutations, but not of low ERG/BAALC expression: a GRAALL study.

Despite recent progress in the understanding of acute lymphoblastic leukemia (T-ALL) oncogenesis, few markers are sufficiently frequent in large subgroups to allow their use in therapeutic stratification. Low ERG and BAALC expression (E/B(low)) and NOTCH1/FBXW7 (N/F) mutations have been proposed as powerful prognostic markers in large cohorts of adult T-ALL. We therefore compared the predictive...

IDH2 mutations are frequent in angioimmunoblastic T-cell lymphoma.

Mutations in isocitrate dehydrogenase 1 (IDH1) and isocitrate dehydrogenase 2 (IDH2) occur in most grade 2 and 3 gliomas, secondary glioblastomas, and a subset of acute myelogenous leukemias but have not been detected in other tumor types. The mutations occur at specific arginine residues and result in the acquisition of a novel enzymatic activity that converts 2-oxoglutarate to D-2-hydroxyglut...

Somatically acquired JAK1 mutations in adult acute lymphoblastic leukemia

Aberrant signal transduction contributes substantially to leukemogenesis. The Janus kinase 1 (JAK1) gene encodes a cytoplasmic tyrosine kinase that noncovalently associates with a variety of cytokine receptors and plays a nonredundant role in lymphoid cell precursor proliferation, survival, and differentiation. We report that somatic mutations in JAK1 occur in individuals with acute lymphoblast...

Not all T wave inversions are ischaemic.

To cite: Rajendran R, Patel JS, Singla V, et al. BMJ Case Reports Published online: [please include Day Month Year] doi:10.1136/ bcr-2012-008219 DESCRIPTION A 52year-old man was referred as a case of acute coronary syndrome (ACS) for he had chest pain, vomiting and deep T wave inversions on ECG. Physical examination was normal except for blood pressure of 190/100 mm Hg. ECG (figure 1) satisfied...
