Kmt2a partial tandem duplication
WebAug 14, 2013 · A tandem duplication can be further classified as either a partial tandem duplication (PTD, e.g. [ 3 ]), if both edges of the duplicated segment correspond to annotated exon boundaries that are involved in splicing (Figure 1 B); or an internal tandem duplication (ITD, e.g. [ 4 ]) otherwise (Figure 1 C).

(A) The wild type MLL gene (MLL WT) is located on chromosome 11 and is approximately 89 kb.The MLL gene encodes mRNAs of at least 36 or 37 exons; both the former (Nilson et al, 1996) and current nomenclatures (Strout et al, 1998) are given (Old and New, respectively).For the …
WebGenomic breakpoints within the KMT2A gene and the involved translocation partner genes (TPGs) and KMT2A-partial tandem duplications (PTDs) were determined. Including the published data from the literature, a total of 107 in-frame KMT2A gene fusions have been identified so far. Further 16 rearrangements were out-of-frame fusions, 18 patients had ... WebKMT2A -PTD is believed to act as an oncogenic driver by modulating the expression of HOX genes (1). However, its exact mechanism of action is not clear. Multiple mutations occur along with KMT2A -PTD and they are usually acquired in a sequential manner: IDH2/DNMT3A/U2AF1/TET2 -> KMT2A -PTD ->RAS-RTK.
WebFor example, presence of both KMT2A (formerly MLL) partial tandem duplication and FLT3-TKD is associated with poorer prognosis, while co-occurrence of NPM1 and FLT3-TKD is associated with improved OS. 2.
