Figure 1. Independent replication with E17.5 brains recapitulates 76.2% (32/42, 0.1 expected by chance) known and 12.9% (51/396, 24 expected by chance) novel imprinted genes reported previously [17].

12,171 (E15) and 10,418 (E17.5) genes were sufficiently powered for detection (≥1 SNP with ≥10 reads), of which 10,222 were in both samples. Reanalysis excluding SNPs detected in parental transcriptomes while relying exclusively on public SNPs marginally changes the outcome of imprint detection (numbers shown in brackets).
