In addition, we observed that XRCC2 and MLL3/KMT2C were located within 7q36.1 (n = 5, 55.6%), which had a q-value 0.057, slightly higher than the threshold 0.05, however, the two genes were involved in the tumorigenesis or progression of several malignant tumors (Figure 2B and Supplementary Table S1), suggesting that these genes might play key roles in schwannoma. Here, XRCC2 is linked to cancer.
