While statistical and expression analyses do not formally exclude any of the genes showing association under the chromosome 10q26 linkage peak with OM, the statistical analyses favour the interval TCERG1L to PPP2R2D (Additional file 2: Figure S1), which lies directly under the peak of linkage for OM at chromosome 10q26, as the most likely candidate region carrying the etiological variants associated with OM susceptibility. Here, PPP2R2D is linked to ocular melanoma.
