Hypermutated tumors respond more favorably to checkpoint inhibitor-based immune therapy. Here, the authors describe a new hypermutated phenotype due to germline mutations and subsequent somatic loss of heterozygosity of MBD4, and a dramatic response to the PD-1 inhibitor pembrolizumab in a patient with a MBD4-inactivated hypermutated uveal melanoma.
