Laboratorios de Investigación en Biología Molecular e Inmunología, Universidad Autónoma de Nayarit RCV000853235 SCV000993545 association Leukemia, acute lymphoblastic 2 criteria provided, single submitter research In a genome wide association study of 317 patient with ALL and 17,958 controls, Trevino et al. (2009) found an association between ALL and 3 SNPs on chromosome 7p12.2. These were in linkage disequilibrium and located in the IKZF1 gene (603023) (rs11978267, p = 8.8 x 10(-11)) and the DDC gene (107930) (rs2167364, p = 2.8 x 10(-6) and rs2242041, p = 9.9 x 10(-7)). Trevino et al. (2009) concluded that germline variants can affect susceptibility to, and characteristics of, ALL and specific ALL sub types. In a genome wide association study of 2 case-control series, totaling 907 ALL cases and 2,398 controls, Papaemmanuil et al. (2009) found a significant association between ALL and a SNP at chromosome 7p12.2 in the IKZF1 gene (rs4132601, OR of 1.69, p = 1.20 x 10(-19)). The association was also highly significant when confined to B-cell ALL (OR of 1.73, p = 9.31 x 10(-20)). In vitro studies showed that IKZF1 mRNA expression was significantly associated with genotype in a dose-dependent fashion, with lower expression being associated with the C risk allele. The authors noted that Ikaros proteins are master regulators of lymphocyte development. By genotyping 1,384 cases of precursor B-cell childhood ALL and 1,877 controls from Germany and the United Kingdom, Prasad et al. (2010) found a significant association between IKZF1 SNP rs4132601 and ALL (OR of 1.69, p = 7.51 x 10(-22)). This finding replicated the susceptibility locus for ALL at chromosome 7p12.2 previously reported by Trevino et al. (2009) and Papaemmanuil et al. (2009).
