To examine the prevalence of HPV integrations at PD-L1 or PD-L2 in other tumor types, we analyzed 229 TCGA HPV-positive cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC) tumors and found no putative HPV integrations at either gene. Here, PDCD1LG2 is linked to cervical squamous cell carcinoma.
