SLC7A8 and acute lymphoblastic leukemia: This revealed an interaction between the 14q11.2 locus and the promoter of SLC7A8 (Supplementary Fig.1A), however no significant association between rs2239630 genotype and SLC7A8 expression was seen in either ALL blasts (P = 0.14, Supplementary Fig.1B), MuTHER (P = 0.31) or blood (P > 0.05) eQTLs datasets.
