Purpose: Clinical and experimental evidence has suggested pathobiological crosstalk between lysosomal storage diseases (LSDs) and cancer. We aimed to elucidate the association between germline variants in LSD genes and cancer. Methods: We performed aggregate rare variant association analysis of potentially pathogenic variants (PPVs) in 42 LSD genes and >30 histological types of cancer using genome sequencing data from 2567 cancer patients (Pan-Cancer cohort) and 2504 healthy individuals (1000 Genomes cohort) and exome sequencing data from 53,105 individuals without cancer (ExAC cohort). Results: PPVs were significantly enriched in the Pan-Cancer cohort compared with the 1000 Genomes cohort (PPV prevalence, 20.7% vs. 13.5%; P = 8.7 × 10−12). Cancer risk was higher in individuals with a greater number of PPVs (P = 7.3 × 10−12). Population structure–adjusted optimal sequence kernel association test (SKAT-O) revealed 37 significantly associated cancer type–LSD gene pairs. These results were supported by the consistent tendency toward enrichment of PPVs in cancer patients compared with the ExAC cohort. Cancer developed earlier in PPV carriers than in wild-type patients. Analysis of tumor transcriptomic data from the pancreatic adenocarcinoma cohort revealed 508 genes differentially expressed according to PPV carrier status, which were highly enriched in the core signaling pathways of pancreatic cancer. Conclusion: Carriers of PPVs in LSD genes are at increased risk of cancer.
