HLA-G and neoplasm: Patients 18 and 30 expressed HLA-G*01:01:08 in their healthy tissue, while the HLA-G expression in tumor tissue was unclear and the typing ambiguities led to potential assignments of alleles such as 01:01:01, 01:01:06, 01:01:08, or 01:03:01 (patient 18), and 01:01:02, 01:01:22, 01:24, or 01:26 (patient 30).
