  1. ...as only one allele is expressed. Allele-specific DNA methylation and chromatin composition are two well-established epigenetic systems that control imprinted gene expression (Fournier et al. 2002; Singh et al. 2010; Prendergast et al. 2012).ASE can reflect differential rates of transcription, m...
  2. ..., referred to as DMR hotspots (Methods). HPV integration sites were then intersected with the DMR hotspots to identify events that potentially affected DNA methylation in an allele-specific manner. Across the samples in our data set, 33 integration event loci overlapped autosomal DMR hotspots (Fig. 6A...
  3. ....Deciphering the genotype-to-phenotype map remains a fundamental quest in biology. Gene expression is a promising focal point, because it is an intermediate step between DNA sequence and gross phenotype. Gene expression itself is a complex trait regulated by genetic, epigenetic, and environmental factors (Pastinen 2010...
  4. ...expression are driven by interactions between transcription factors, regulatory DNA sequences, and chromatin. How DNA mutations affecting any one of these regulatory “layers” are buffered or propagated to gene expression remains unclear. To address this, we quantified allele-specific changes in chromatin...

  6. ...by ligation to TruSeq Illumina adapters with T4 DNA ligase (Enzymatics). BAM files were filtered to remove read-pairs which mapped to ribosomal DNA sequences.Allele-specific alignment and data analysisReads of quality scores above 30 were independently mapped to 129/sv and castaneus reference s using Bowtie 2...
  7. ...these questions, we first analyzed two independent data sets comprising PCR-free whole- sequencing (WGS) and -wide DNA methylation levels derived from whole-blood samples in 245 (discovery cohort) and 484 individuals (replication cohort). Using genotypes for 131,635 polymorphic STRs derived from WGS using Hip...

Lee JH, Park IH, Gao Y, Li JB, Li Z, Daley GQ, Zhang K, Church GM. 2009. A robust approach to identifying tissue-specific gene expression regulatory...
  9. ...haplotype A or B, which served as input to our Bayesian model. As the RNA-seq data from Pickrell et al. (2010) were not accompanied by genomic DNA sequence data, we used the same estimates of the dispersion in read counts as our full analysis of the yeast data (i.e., the analysis of Illumina and ABI Allele-specific...
  10. ...analysis was performed on a PSQ HS96 Pyrosequencer (Biotage) according to the manufacturer’s protocol. All allele-specific expression analysis was performed in triplicate (Supplemental Table 3). Oligonucleotide reconstitution experiment We synthesized 130 biotinylated 45-nt oligonucleotides (Integrated DNA...
