Notable associations were observed for two additional intronic SLC23A2 SNPs, rs6133175 (IVS4+1767A>G) and rs1715364 (IVS3+14205T>C) (q<0.05), where the homozygous variant genotypes yielded two-fold increased risks for SLL/CLL (Table S1). This evidence concerns the gene SLC23A2 and B-cell chronic lymphocytic leukemia.
