Overall, the data suggest that variants in the intergenic region between TCERG1L and PPP2R2D, which lies at 133.2 Mb directly under the peak of linkage (Table 3), as well as in DOCK1 (128.8 Mb) and ADAM12 (127.9 Mb), may contribute independently to susceptibility to OM. This evidence concerns the gene PPP2R2D and ocular melanoma.
