A Case Report of Concurrent IDH1 and NPM1 Mutations in a Novel t(X;2)(q28;p22) Translocation in Acute Myeloid Leukaemia without Maturation (AML-M1).

Acute myeloid leukaemia (AML) is one of the fatal haematological malignancies as a consequence of its genetic heterogeneity. At present, the prediction of the clinical response to treatment for AML is based not only on detection of cytogenetic aberrations but also by analysing certain molecular genetic alterations. There are limited in sights into the contribution, disease progression, treatment outcome, and characterisation with respect to the uncommon chromosomal abnormalities leading to AML. Here, we describe the clinical, morphological, cytogenetic, and mutational findings of a 52-year-old female patient with AML without maturation (AML-M1). Conventional karyotyping and spectral karyotyping (SKY) were done on metaphase chromosomes from bone marrow cells at the time of diagnosis. A mutation analysis was performed on the hotspot regions of various genes, including and Cytogenetic and mutation analyses revealed a novel translocation, t(X;2)(q28;p22), with both and mutations. To the best of our knowledge, the presence of both NPM1 and IDH1 mutations in t(X;2)(q28;p22) is a novel finding in AML.
