 The 11p15.5 region harbors three imprinted sense/antisense transcript pairs, SLC22A18/SLC22A18AS, IGF2/IGF2AS (PEG8), and KCNQ1/KCNQ1OT1 (LIT1).     ///    "Random hexamer-primed cDNA synthesis, SLC22A18/SLC22A18AS-specific PCR, and imprinting evaluation by commercial sequencing demonstrated that SLC22A18AS displays a nonimprinted profile in reduction mastectomies (n = 6).
