We then performed bisulfite sequencing PCR combined with HiSeq sequencing (HiSeq-BSP) (Gao et al. 2014; Mensaert et al. 2014) and nine genes (MTMR1, HAUS7, FAM127C, AIFM1, PIM2, TWIST2, IRAK1, BCAP31, and SOX3) were successfully cloned to validate these DMRs in another six pairs of piglets (IUGR/NBW pair 5–10). This evidence concerns the gene HAUS7 and fetal growth restriction.
