A selection of key genes involved in piebald.

A selection of key genes differentially expressed (DE; PP1The mean normalised gene expression is given for each of five tissue types (NOR, PBB, PBW, RSB and RSW as define in Figure 2A). Values for piebald tissue (PBB or PBW) that are higher than in the normal tissue (NOR) indicate up regulation (eg ATRN).2SNP with the highest association within a 1 Mb region centered on the gene.3Allele frequencies are given in both the piebald and non-piebald animal populations.4Both the P-value and associated odd ratio (OR) are given for SNP2. See Table S1 for full list of 312 key genes. Genes in bold type correspond to genes located at the intersection between the regulatory and the epistatic network (Figure 3).
