Chromosomal translocation affecting the 3q27 band, where the BCL6 gene is localized, is one of the most common genetic abnormalities in non-Hodgkin's lymphoma of B-cell type (B-NHL).
These data suggest that the inactivating mutations of the CASP10 gene might lead to the loss of its apoptotic function and contribute to the pathogenesis of some human NHLs.
The NBS1 mutation 657del5 on one allele was found in 3 of 270 patients with ALL and 2 of 212 children and adolescents with NHL; no carrier was found among 63 patients with Hodgkin lymphoma (HL).
These findings imply that heterozygous NBS1 germline mutations may contribute significantly to the overall incidence of NHL, especially of the gastrointestinal tract, in Central Europe.
A haplotype comprising SNPs in two proinflammatory cytokines, tumor necrosis factor-alpha and lymphotoxin-alpha (rs1800629, rs361525, rs1799724, rs909253, and rs2239704), increased non-Hodgkin lymphoma risk overall (OR, 1.31; 95% CI, 1.06-1.63; P = 0.01) and notably for diffuse large B cell (OR, 1.64; 95% CI, 1.23-2.19; P = 0.0007).
Although no direct association was found between IL-10 promoter polymorphisms and NHL, IL-10 (-1082) AA homozygosity and IL-10 ACC genotype were found to be associated with unfavourable prognosis in patients with NHL.
Five hundred patients with aggressive NHL treated with CHOP/CHOEP were analyzed for IL-10 gene polymorphisms, including distal loci -7400InDel, -6752AT (rs6676671), and -6208CG (rs10494879) in comparison with proximal loci -3538AT (rs1800890), -1087AG (rs1800896), and -597AC (rs1800872) according to the incidence and outcome of the lymphoma.
Here we show that the anaplastic lymphoma kinase (ALK), originally identified as a fusion kinase in a subtype of non-Hodgkin's lymphoma (NPM-ALK) and more recently in adenocarcinoma of lung (EML4-ALK), is also a frequent target of genetic alteration in advanced neuroblastoma.
A haplotype comprising SNPs in two proinflammatory cytokines, tumor necrosis factor-alpha and lymphotoxin-alpha (rs1800629, rs361525, rs1799724, rs909253, and rs2239704), increased non-Hodgkin lymphoma risk overall (OR, 1.31; 95% CI, 1.06-1.63; P = 0.01) and notably for diffuse large B cell (OR, 1.64; 95% CI, 1.23-2.19; P = 0.0007).
Risk estimation for each genotype by the unconditional logistic model demonstrated the possible association between the p53 Pro72 allele and the risk of non-Hodgkin's lymphoma in Japanese population (OR = 1.59; 95% CI, 0.99-2.57, P = 0.057), although no other significant association was observed.
Our data provide evidence that NAT1 and NAT2 genotypes are associated with NHL risk and support a contributory role for carcinogenic aromatic and/or heterocyclic amines in the multi-factorial etiology of NHL.
In this population-based case control study (n = 455 cases; 527 controls), we examined the only identified nonsynonymous polymorphism (Ala394Thr; rs2305160) in the largest circadian gene, neuronal PAS domain protein 2 (NPAS2), in order to examine its impact on NHL risk.
