Built on its successes, we propose a general analysis framework to leverage multi-omics data with sequencing data to improve the statistical power of discovering new associations and understanding of the disease susceptibility due to low-frequency variants. The proposed test features its robustness to model misspecification, high power across a wide range of scenarios and the potential of offering insights into the underlying genetic architecture and disease mechanisms.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Using the Framingham Heart Study data, we show that low-frequency variants are predictive of DNA methylation, even after conditioning on the nearby common variants. In addition, DNA methylation and gene expression provide complementary information to functional genomics. In the Avon Longitudinal Study of Parents and Children with a sample size of 1497, one gene CLPTM1 is identified to be associated with low-density lipoprotein cholesterol levels by the proposed powerful adaptive gene-based test integrating information from gene expression, methylation and enhancer\u2013promoter interactions. It is further replicated in the TwinsUK study with 1706 samples. The signal is driven by both low-frequency and common variants.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Availability and implementation<\/jats:title>\n                  <jats:p>Models are available at https:\/\/github.com\/ytzhong\/DNAm.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Supplementary information<\/jats:title>\n                  <jats:p>Supplementary data are available at Bioinformatics online.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/bioinformatics\/btaa898","type":"journal-article","created":{"date-parts":[[2020,10,7]],"date-time":"2020-10-07T03:36:58Z","timestamp":1602041818000},"page":"5223-5228","source":"Crossref","is-referenced-by-count":4,"title":["Integrative analysis of multi-omics data for discovering low-frequency variants associated with low-density lipoprotein cholesterol levels"],"prefix":"10.1093","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0162-7740","authenticated-orcid":false,"given":"Tianzhong","family":"Yang","sequence":"first","affiliation":[{"name":"Department of Biostatistics, School of Public Health, University of Minnesota , Minneapolis, MN 55455, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7758-6116","authenticated-orcid":false,"given":"Peng","family":"Wei","sequence":"additional","affiliation":[{"name":"Department of Biostatistics, The University of Texas MD Anderson Cancer Center , Houston, TX 77030, USA"}]},{"given":"Wei","family":"Pan","sequence":"additional","affiliation":[{"name":"Department of Biostatistics, School of Public Health, University of Minnesota , Minneapolis, MN 55455, USA"}]}],"member":"286","published-online":{"date-parts":[[2020,10,18]]},"reference":[{"key":"2023062408061691600_btaa898-B1","doi-asserted-by":"crossref","first-page":"773","DOI":"10.1038\/nrg2867","article-title":"Statistical analysis strategies for association studies involving rare variants","volume":"11","author":"Bansal","year":"2010","journal-title":"Nat.
