Genetic Epidemiology and Variant Discovery
The Genetic Epidemiology and Variant Discovery team are focused on the use of next generation sequencing methods to generate data to map genetic variation and applying population-based approaches to identify disease risk variants. Large population based studies using genome wide-association study (GWAS) approaches have identified more than 30 germline risk loci for ovarian cancer, and we are now focused on understanding how these loci increase disease risk, and how they direct disease initiation and progression.
Understanding how Ovarian Cancer risk loci increase disease risk.
Using genetic epidemiology tools to integrate genetic information with clinical, demographic and environmental data will improve risk estimation will allow clinicians to improve monitoring and disease prevention. We apply statistical approaches to model how germline risk variants combine with environmental risk factors to contribute to heritable disease risk. We are also using novel statistical methods to investigate how non-coding variants in gene regulatory regions contribute to heritability.
Identifying how Ovarian Cancer risk loci affect disease biology.
Now that we have identified a number of ovarian cancer risk loci it is critical that we understand how these variants lead to ovarian cancer. Functional annotation of risk loci with genomic datasets in collaboration with Dr. Dennis Hazelett and Simon Coetzee is combined with the “Jasmine’s Team” to identify the functional role of credible causal variants that are identified by fine mapping.
Mapping novel variants for Ovarian Cancer.
It is a major mission of the team to transition from SNP-array based studies to next-generation sequencing (with a particular focus on whole genome sequencing) studies for variant discovery. This includes developing pipelines for sample handling and quality control, data generation and informatics for data QC and analysis. Our current projects include the discovery of rare variants by exome and targeted sequencing panels. Planned projects using WGS will pursue the role of germline risk variants in somatic tissue and interrogate the accrual of mutations surrounding germline risk loci.

Dr. Michelle Jones - Project Scientist - Center for Bioinformatics and Functional Genomics at Cedars-Sinai Medical Center (Michelle.Jones@csmc.edu)
Dr. Jones completed her BSc in Molecular Biology at Murdoch University, Western Australia where she worked with Dr. Scott Wilson (University of Western Australia, Sir Charles Gairdner Hospital) on gene discovery in Polycystic Ovary Syndrome (PCOS).In 2007 Dr. Jones joined the Division of Endocrinology at Cedars-Sinai Medical Center (CSMC) where she continued her work on the genetics is PCOS, and completed her PhD. Her post doctoral fellowship focused on systems genetics approaches to PCOS, integrating variant, methylation and expression data at germline risk loci. Dr. Jones remains an active analyst in the iPCOS Genetics Consortium. In 2016 Dr. Jones joined the Center for Bioinformatics and Functional Genomics to lead the Genetic Epidemiology and Variant Discovery team together with Dr. Gayther.
Alberto Reyes - Research Associate I - Center for Bioinformatics and Functional Genomics at Cedars-Sinai Medical Center (AlbertoLuiz.Reyes@cshs.org)
Alberto Reyes attended the University of California, Los Angeles from 2012 to 2016 where he earned a Bachelor of Science in Statistics. He served as an undergraduate research assistant under Professor Jingyi Li from 2013 to 2014. He participated in various projects involving RNA-seq and differential gene expression. He was also an undergraduate research assistant in the Kosuri lab under Professor Sriram Kosuri from July to December of 2016. While there, he investigated underlying causes of drop outrate in multiplex gene synthesis. Alberto joined the Center for Bioinformatics and Functional Genomics in January 2017 and works under Dr. Michelle Jones, Dr. Simon Gayther, and Dr. Benjamin Berman.
