A latest meta-analysis of 21 published case–control studies with 3815 cases and 5802 controls was performed by Almeida et al. in 2018 [54]; however, they assessed the relationship between the HLA-G 14 bp Ins/Del polymorphism and the risk of cancer only in the allelic comparisons (Ins vs. Del), and no positive results were found. Here, HLA-G is linked to cancer.
