• The application of advanced molecular technology has significantly expanded lymphoma classification, allowing risk stratification and treatment optimization. Limited evidence suggests the presence of a genetic predisposition in lymphoma, indicating the potential for better individualized clinical management based on a novel lymphoma classification. Herein, we examined the impact of germline pathogenic variants in 27 cancer‐predisposing genes with lymphoma risk and explored the clinical characteristics of pathogenic variant carriers. This study included 2,066 lymphoma patients and 38,153 cancer‐free controls from the Japanese population. Following quality control of sequencing data, samples from 1,982 lymphoma patients and 37,592 controls were further analyzed. We identified 309 pathogenic variants among 4,850 variants in the 27 cancer‐predisposing genes. Pathogenic variants in the following four cancer‐predisposing genes were associated with a high risk of lymphoma: ATM (odds ratio [OR], 2.63; 95% confidence interval [CI], 1.25–5.51; p = 1.06 × 10−2), BRCA1 (OR, 5.88; 95% CI, 2.65–13.02; p = 1.27 × 10−5), BRCA2 (OR, 2.94; 95% CI, 1.60–5.42; p = 5.25 × 10−4), and TP53 (OR, 5.22; 95% CI, 1.43–19.02; p = 1.23 × 10−2). The proportion of carriers of these genes was 1.6% of lymphoma patients. Furthermore, pathogenic variants in these genes were especially associated with a higher risk of mantle cell lymphoma (OR, 21.57; 95% CI, 7.59–61.26; p = 8.07 × 10−9). These results provide novel insights concerning monogenic form into lymphoma classification. Some lymphoma patients may benefit from surveillance and targeted treatment, such as other neoplasms. We found that pathogenic variants in the four cancer‐predisposing genes (ATM, BRCA1, BRCA2, and TP53) were associated with lymphoma risk. Pathogenic variants in these genes were especially associated with a higher risk of mantle cell lymphoma. These results would provide novel insights concerning monogenic form into lymphoma classification.
