Within the selected candidate genes, the FTO gene (Alpha-ketoglutarate dependent dioxygenase) has been associated with porcine carcass traits [72] and it is target of multiple obesity-related studies in human [73, 74], however candidate SNPs within these last two genes could not been identified from the RNA-Seq segregating in BC_DU. The gene discussed is FTO; the disease is obesity due to melanocortin 4 receptor deficiency.
