Also known as IMPT1, BWR1A, TSSC5 and ORCTL2, SLC22A18 is located in 11p15.5, a chromosomal region which is frequently deleted in a variety of cancers [7] and encompasses several imprinted genes most of which including SLC22A18 show preferential expression of the maternal allele [8, 9]. This evidence concerns the gene SLC67A1 and cancer.
