The spectrum of chromosomal translocations in the Arab world: ethnic-specific chromosomal translocations and their relevance to diseases. Chromosoma 2022; 131:127-146. [PMID: 35907041 PMCID: PMC9470631 DOI: 10.1007/s00412-022-00775-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Revised: 05/13/2022] [Accepted: 06/23/2022] [Indexed: 11/04/2022]
Abstract
Chromosomal translocations (CTs) are the most common type of structural chromosomal abnormalities in humans. CTs have been reported in several studies in the Arab world, but the frequency and spectrum of these translocations are not well characterized. The aim of this study is to conduct a systematic review to estimate the frequency and spectrum of CTs in the 22 Arab countries. Four literature databases were searched: PubMed, Science Direct, Scopus, and Web of Science, from the time of inception until July 2021. A combination of broad search terms was used to collect all possible CTs reported in the Arab world. In addition to the literature databases, all captured CTs were searched in three chromosomal rearrangement databases (Mitelman Database, CytoD 1.0 Database, and the Atlas of Genetics and Cytogenetics in Oncology and Hematology), along with PubMed and Google Scholar, to check whether the CTs are unique to the Arabs or shared between Arabs and non-Arabs. A total of 9,053 titles and abstracts were screened, of which 168 studies met our inclusion criteria, and 378 CTs were identified in 15 Arab countries, of which 57 CTs were unique to Arab patients. Approximately 89% of the identified CTs involved autosomal chromosomes. Three CTs, t(9;22), t(13;14), and t(14;18), showed the highest frequency, which were associated with hematological malignancies, recurrent pregnancy loss, and follicular lymphoma, respectively. Complex CTs were commonly reported among Arabs, with a total of 44 CTs, of which 12 were unique to Arabs. This is the first study to focus on the spectrum of CTs in the Arab world and compressively map the ethnic-specific CTs relevant to cancer. It seems that there is a distinctive genotype of Arabs with CTs, of which some manifested with unique clinical phenotypes. Although ethnic-specific CTs are highly relevant to disease mechanism, they are understudied and need to be thoroughly addressed.

Abstract
Leukemia is the most common pediatric cancer, affecting 3800 children per year in the United States. Its annual incidence has increased over the last decades, especially among Latinos. Although most children diagnosed with leukemia are now cured, many suffer long-term complications, and primary prevention efforts are urgently needed. The early onset of leukemia-usually before 5 years of age-and the presence at birth of "pre-leukemic" genetic signatures indicate that pre- and postnatal events are critical to the development of the disease. In contrast to most pediatric cancers, there is a growing body of literature-in the United States and internationally-that has implicated several environmental, infectious, and dietary risk factors in the etiology of childhood leukemia, mainly for acute lymphoblastic leukemia, the most common subtype. For example, exposures to pesticides, tobacco smoke, solvents, and traffic emissions have consistently demonstrated positive associations with the risk of developing childhood leukemia. In contrast, intake of vitamins and folate supplementation during the preconception period or pregnancy, breastfeeding, and exposure to routine childhood infections have been shown to reduce the risk of childhood leukemia. Some children may be especially vulnerable to these risk factors, as demonstrated by a disproportionate burden of childhood leukemia in the Latino population of California. The evidence supporting the associations between childhood leukemia and its risk factors-including pooled analyses from around the world and systematic reviews-is strong; however, the dissemination of this knowledge to clinicians has been limited. To protect children's health, it is prudent to initiate programs designed to alter exposure to well-established leukemia risk factors rather than to suspend judgment until no uncertainty remains. Primary prevention programs for childhood leukemia would also result in the significant co-benefits of reductions in other adverse health outcomes that are common in children, such as detriments to neurocognitive development.

Abstract
MLL (myeloid/lymphoid or mixed-lineage leukemia) rearrangements are frequent in therapy-related and childhood acute leukemia, and are associated with poor prognosis. The majority of the rearrangements fall within a 7.3-kb MLL breakpoint cluster region (MLLbcr), particularly in a 0.4-kb hotspot at the intron11-exon12 boundary. The underlying mechanisms are poorly understood, though multiple pathways including early apoptotic signaling, accompanied by high-order DNA fragmentation, have been implicated. We introduced the MLLbcr hotspot in an EGFP-based recombination reporter system and demonstrated enhancement of both spontaneous and genotoxic treatment-induced DNA recombination by the MLLbcr in various human cell types. We identified Endonuclease G (EndoG), an apoptotic nuclease, as an essential factor for MLLbcr-specific DNA recombination after induction of replication stress. We provide evidence for replication stress-induced nuclear accumulation of EndoG, DNA binding by EndoG as well as cleavage of the chromosomal MLLbcr locus in a manner requiring EndoG. We demonstrate additional dependency of MLLbcr breakage on ATM signaling to histone H2B monoubiquitinase RNF20, involved in chromatin relaxation. Altogether our findings provide a novel mechanism underlying MLLbcr destabilization in the cells of origin of leukemogenesis, with replication stress-activated, EndoG-mediated cleavage at the MLLbcr, which may serve resolution of the stalled forks via recombination repair, however, also permits MLL rearrangements.
