Description:
The extent to which variation in chromatin structure and transcription factor binding may influence gene expression, and thus underlie or contribute to variation in phenotype, is unknown. To address this question, we cataloged both individual-to-individual variation and differences between homologous chromosomes within the same individual (allele-specific variation) in chromatin structure and transcription factor binding in lymphoblastoid cells derived from individuals of geographically diverse ancestry. Ten percent of active chromatin sites were individual-specific; a similar proportion were allele-specific. Both individual-specific and allele-specific sites were commonly transmitted from parent to child, which suggests that they are heritable features of the human genome. Our study shows that heritable chromatin status and transcription factor binding differ as a result of genetic variation and may underlie phenotypic variation in humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2929018/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2929018/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McDaniell, Ryan -- Lee, Bum-Kyu -- Song, Lingyun -- Liu, Zheng -- Boyle, Alan P -- Erdos, Michael R -- Scott, Laura J -- Morken, Mario A -- Kucera, Katerina S -- Battenhouse, Anna -- Keefe, Damian -- Collins, Francis S -- Willard, Huntington F -- Lieb, Jason D -- Furey, Terrence S -- Crawford, Gregory E -- Iyer, Vishwanath R -- Birney, Ewan -- U54 HG004563/HG/NHGRI NIH HHS/ -- U54 HG004563-03/HG/NHGRI NIH HHS/ -- Z01 HG000024/HG/NHGRI NIH HHS/ -- Z01 HG000024-13/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Apr 9;328(5975):235-9. doi: 10.1126/science.1184655.
