In this study, gene colocalization analysis of five proteins suggested that PPIE may have a pathogenic variant in this region (PP.H4 = 0.758); POMGNT2 (PP.H4 = 0.603) and CCL14 (PP.H4 = 0.549) showed moderate colocalization with CLL (Fig. 4). Here, CCL14 is linked to B-cell chronic lymphocytic leukemia.
