    Abstract: Background: Genome-wide association studies (GWAS) in European populations have identified genetic risk variants associated with multiple myeloma. Methods: We performed association testing of common variation in eight regions in 1,318 patients with multiple myeloma and 1,480 controls of European ancestry and 1,305 patients with multiple myeloma and 7,078 controls of African ancestry and conducted a meta-analysis to localize the signals, with epigenetic annotation used to predict functionality. Results: We found that variants in 7p15.3, 17p11.2, 22q13.1 were statistically significantly (P & lt; 0.05) associated with multiple myeloma risk in persons of African ancestry and persons of European ancestry, and the variant in 3p22.1 was associated in European ancestry only. In a combined African ancestry–European ancestry meta-analysis, variation in five regions (2p23.3, 3p22.1, 7p15.3, 17p11.2, 22q13.1) was statistically significantly associated with multiple myeloma risk. In 3p22.1, the correlated variants clustered within the gene body of ULK4. Correlated variants in 7p15.3 clustered around an enhancer at the 3′ end of the CDCA7L transcription termination site. A missense variant at 17p11.2 (rs34562254, Pro251Leu, OR, 1.32; P = 2.93 × 10−7) in TNFRSF13B encodes a lymphocyte-specific protein in the TNF receptor family that interacts with the NF-κB pathway. SNPs correlated with the index signal in 22q13.1 cluster around the promoter and enhancer regions of CBX7. Conclusions: We found that reported multiple myeloma susceptibility regions contain risk variants important across populations, supporting the use of multiple racial/ethnic groups with different underlying genetic architecture to enhance the localization and identification of putatively functional alleles. Impact: A subset of reported risk loci for multiple myeloma has consistent effects across populations and is likely to be functional. Cancer Epidemiol Biomarkers Prev; 25(12); 1609–18. ©2016 AACR.

    Abstract: Background and Objective: DNA repair is an essential process for development and differentiation of all cells, including plasma cells. Associations between single nucleotide polymorphisms (SNPs) in DNA repair genes and multiple myeloma risk have been reported but generally not replicated. In a pilot study, we observed suggestive evidence of an association between multiple myeloma risk and five nonsynonymous SNPs in DNA repair genes (rs25489 in XRCC1, rs1801516 in ATM, rs2227999 in XPC, rs2228528 in CSB and rs2228615 in ICAM5). The objective of this study was to examine the effect of these five SNPs on multiple myeloma risk in a large multi-center analysis. Methods: We conducted a pooled analysis in a multi-ethnic sample of 489 multiple myeloma cases and 939 controls. Studies contributing samples included two population-based case-control studies conducted in Los Angeles and Seattle/Detroit that used the Surveillance, Epidemiology and End Results (SEER) cancer registries to identify cases, and three nested case-control studies using subjects from the Multiethnic Cohort (MEC), the Health Professionals Follow Up Study (HPFS), and the Nurses’ Health Study (NHS). The SNPs coded for an amino acid substitution, and were assumed to have the same effect across ethnic groups, and thus subjects from all racial/ethnic groups were included in the analysis. Assuming a log-additive inheritance model, odds ratios (OR) and 95% confidence intervals (95% CIs) were calculated for allele-specific risk comparing cases to controls using unconditional logistic regression, adjusting for age, race/ethnicity, sex, and study site. Results: We observed a 40% decreased risk per variant T allele in the XRCC1 SNP rs25489 (OR=0.60, 95% CI=0.40, 0.91, p-value=0.02). The minor allele frequency in cases and controls was 3.4% and 5.6%, respectively. Non-significant OR's & lt; 1.0 were observed when whites (OR=0.67, 95% CI=0.38, 1.17) and African Americans (OR=0.33, 95% CI= 0.09, 1.20) were considered separately. The SNPs in other DNA repair genes, ATM (rs1801516), XPC (rs2227999), CSB (rs2228528) and ICAM5 (rs2228615), showed no association with multiple myeloma risk. Conclusion: We observed an association between multiple myeloma and XRCC1, a gene that encodes a protein involved in the repair of single-stranded DNA breaks caused by ionizing radiation and alkylating agents. The variant allele of rs25489 results in a missense mutation substituting an amino acid (Arg & gt; His). Several studies have shown diminished DNA repair capacity associated with the variant allele of this SNP, an effect which may be relevant to multiple myeloma etiology. Replication in additional studies is needed to validate this finding. Citation Format: {Authors}. {Abstract title} [abstract].

    Abstract: Background: Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma subtype and is clinically aggressive. Relatives of DLBCL patients are at elevated risk for DLBCL. In small genome-wide association studies (GWAS) in which all NHL subtypes were combined, no conclusive loci for DLBCL have been previously identified in individuals of European background, whereas a recent study conducted in East Asia identified a locus at 3q27. Methods: To identify genetic susceptibility loci for DLBCL, we conducted a meta-analysis of three new GWAS and one prior scan, totaling 3,857 DLBCL cases and 7,666 controls of European ancestry. Imputation was used to combine all the data using the 1000 Genomes Project release v3 and IMPUTE2. Based on these findings, we selected 6 promising SNPs for genotyping in an additional 202 cases and 3,431 controls, which were then included in a second meta-analysis. SNPTEST was used to estimate odds ratios (ORs), using the additive model and adjusting for age, gender and significant eigenvectors. Results: In our multi-stage analysis, five independent SNPs in four loci achieved genome-wide significance marked by rs116446171 at 6p25.3 (EXOC2; OR=2.33, P=1.60x10-20), rs13255292 and rs4733601 at 8q24.21 (PVT1; OR=1.23, P=4.86x10-12 and OR=1.18, P=1.63x10-8, respectively), rs2523607 at 6p21.33 (HLA-B; OR=1.34, 3.35x10-9) and rs2681416 at 3q13.33 (CD86; OR=1.20, P=6.04x10-9). The two 8q24.21 SNPs displayed minimal linkage disequilibrium (r2=0.03) and conditional analysis supported their independence. We did not observe a notable signal for a locus previously reported for DLBCL on 3q27 in East Asia, rs6773854 (OR=1.06, P=0.81). We estimated that common SNPs, including but not limited to the loci discovered in this study, explain approximately 16% of the variance for DLBCL risk overall. Discussion: The susceptibility locus at 6p25.3 maps near a plausible DLBCL candidate gene, EXOC2 (exocyst complex component 2), which interacts with Ral proteins, and disruption of the Ral-exocyst regulatory node impacts cellular and developmental processes associated with malignant transformation and progression. The two 8q24.21 variants are approximately 1Mb telomeric to the 8q24 region linked with multiple cancers including CLL. Both variants are positioned in close proximity to PVT1, which is a non-coding RNA implicated in the MYC activation, and MYC is known to be deregulated in some DLBCLs. The locus at 3q13.33 maps to CD86 (B7-2), a B-7 family member that along with CD80 (B7-1) is essential in cognate interactions between T- and B-lymphocytes; both play key roles in immunodeficiency, autoimmune diseases, and in anti-tumor immunity. Finally, we had multiple signals in the HLA region, the strongest of which was at 6p21.33 near HLA-B. HLA-B encodes the HLA class I heavy chain paralogue, which heterodimerizes with a light chain (β2 microglobulin) and plays a central role in presenting intracellularly processed self or foreign antigens to CD8+ cytotoxic T lymphocytes. Class I molecules have been extensively linked to the risk of a variety of immune-mediated diseases and cancers including DLBCL. Conclusions: These data provide substantial new evidence for genetic susceptibility to this B-cell malignancy, and point towards pathways involved in immune recognition and immune function in the pathogenesis of DLBCL.

    Abstract: Tobacco smoking and alcohol consumption have been intensively studied in the general population to assess their effects on the risk of breast cancer, but very few studies have examined these effects in BRCA1 and BRCA2 mutation carriers. Given the high breast cancer risk for mutation carriers and the importance of BRCA1 and BRCA2 in DNA repair, better evidence on the associations of these lifestyle factors with breast cancer risk is essential. Methods: Using a large international pooled cohort of BRCA1 and BRCA2 mutation carriers, we conducted retrospective (5,707 BRCA1 mutation carriers and 3,525 BRCA2 mutation carriers) and prospective (2,276 BRCA1 mutation carriers and 1,610 BRCA2 mutation carriers) analyses of alcohol and tobacco consumption using Cox proportional hazards models. Results: For both BRCA1 and BRCA2 mutation carriers, none of the smoking-related variables was associated with breast cancer risk, except smoking for more than 5 years before a first full-term pregnancy (FFTP) when compared with parous women who never smoked. For BRCA1 mutation carriers, the HR from retrospective analysis (HRR) was 1.19 [95% confidence interval (CI), 1.02–1.39] and the HR from prospective analysis (HRP) was 1.36 ( 95% CI, 0.99–1.87). For BRCA2 mutation carriers, smoking for more than 5 years before an FFTP showed an association of a similar magnitude, but the confidence limits were wider (HRR = 1.25; 95% CI, 1.01–1.55 and HRP = 1.30; 95% CI, 0.83–2.01). For both carrier groups, alcohol consumption was not associated with breast cancer risk. Conclusions: The finding that smoking during the prereproductive years increases breast cancer risk for mutation carriers warrants further investigation. Impact: This is the largest prospective study of BRCA mutation carriers to assess these important risk factors.
