Abstract

Review on t(2;11)(p21;q23) with MLL (KMT2A) involvement, with data on clinics, and the genes involved.

Clinics and Pathology

Disease

Myelodysplastic syndromes: (MDS), acute myeloid leukemia: (AML) and acute lymphoblastic leukemia (ALL).

Phenotype stem cell origin

Although at least 43 cases of t(2;11)(p21;q23) have been described in hematological malignancies (19 MDS, 21 AML, 2 acute lymphocytic leukemia (ALL) and 1 chronic lymphocytic leukemia: (CLL) (Mitelman et al., 2016)., The implication of MLL was ascertained in only 5 cases (Thirman et al., 1993; Finke et al., 1994; Fleischman et al., 1999; Kim et al., 2002; Meyer et al., 2006), a case with a hidden involvement of AFF3 (2q11) being discarded (Hiwatari et al., 2003), while thirty two case of t(2;11)(p21;q23) without MLL rearrangement are available (review in Ruano and Shetty, 2016). There were a case of refractory anemia with excess of blasts: (RAEB) evolving towards an AML, a M0-AML: evolving towards a M4-AML, a M5a-AML, and two ALLs.

Epidemiology

Sex ration was 3M/1F. Patients were aged 8 months, 58, 58, and 61 years (Thirman et al., 1993; Finke et al., 1994; Fleischman et al., 1999; Kim et al., 2002).

Genes Involved and Proteins

Note
the gene involved in 2p in unknown
Gene name
KMT2A (myeloid/lymphoid or mixed lineage leukemia)
Location
11q23.3
Dna rna description
37 exons, spanning about 120 kb; 13-15 mRNA
Protein description
3969 amino acids, 431 kDa; Transcriptional regulatory factor. MLL is known to be associated with more than 30 proteins, including the core components of the SWI/SNF chromatin remodeling complex and the transcription complex TFIID. MLL binds promotors of HOX genes through acetylation and methylation of histones. MLL is a major regulator of hematopoesis and embryonic development, through regulation of HOX genes expression regulation (HOXA9 in particular).
