LEPR and obesity due to melanocortin 4 receptor deficiency: LEPR SNPs c.2002C>T (genotyped by pyrosequencing), located in exon 14, showed strong associations with backfat in Iberian × Meishan and Landrace pig populations, and demonstrated that the T allele in c.2002C>T is a marker for a tendency toward obesity [75,76,77].
