  1. a Intergn intergenic ZFP57 binding upstream (5′) or downstream (3′) of the gene. Each row shows the gene name, position of the associated ZFP57 binding site and percentage of BL6 allelic expression ascertained by SNP pyrosequencing (i.e., 100 % = exclusively BL6, 0 % = exclusively Cast and 50 % = perfect biallelic expression). cDNA from four hybrid ES and neural stem cells was analyzed and compared with their corresponding genomic control for PCR bias (gDNA). Values in bold font emphasize significant C57BL/6 or Cast preferential allelic expression (p < 0.01, median difference greater than 15 % compared with genomic DNA control). For Sdk2, where no gDNA is available, ES cells are compared relative to neural stem cell expression. (*p < 0.05, **p < 0.01, ***p < 0.001 repeated measures ANOVA with Bonferroni’s post-test; NS not significant). See also Fig. S10 in Additional file 1 and Fig. 6 highlighting the relative expression level and allelic preference for eight highlighted genes.
