Precision Health

Available Data and Biosamples

 

The UCLA ATLAS Community Health Initiative represents a unique, diverse collection of clinical and genomic data from patients across the UCLA Health system. As of February 2026, more than 250,000 patients across UCLA Health have provided consent. A subset of these patients have DNA samples that have been sequenced and genotyped. Sample collection and sequencing efforts are ongoing, and the dataset will continue to be updated as additional data become available. Please review Guidelines for Utilizing Universal Consent and Precision Health Data and Samples in Clinical Studies for any potential collaboration with IPH. 

ATLAS Data Access and Research Resources

The UCLA Institute for Precision Health (IPH) provides UCLA-approved researchers with access to de-identified ATLAS clinical and genomic data through two complementary research environments: ULEAD and the UCLA Biomedical Data Commons (BDC) Cohort Browser. The UCLA BDC Cohort Browser is a free research tool that enables researchers to explore available clinical and genomic data, identify relevant patient populations, and assess the feasibility of potential research studies. It is designed to support cohort discovery and research planning.
 
ULEAD provides a secure, self-service research computing environment for researchers with bioinformatics expertise who need to work directly with de-identified ATLAS data. It includes genomic and EHR data, virtual machines for development and processing, storage, software, and code. The environment supports computational analysis through high-performance computing (HPC), accessed via SSH clients and integrated development environments (IDEs), with AlmaLinux, a centrally managed Slurm scheduler, and preconfigured software modules. Available ATLAS resources include summarized data files, Jupyter notebook profiling templates, an ATLAS code repository, and microarray and whole-exome sequencing data in VCF and PLINK formats.
 
ATLAS data access is limited to UCLA researchers and is governed by applicable institutional requirements, including IRB approvals and data use agreements. Curated data releases are version-controlled and accompanied by documentation to support reproducibility and transparency. See below for available datasets.

Sample Request

Requests for DNA samples from participants in ATLAS will undergo an evaluation process, overseen by the IPH Scientific Review Committee (SRC), comprised of content expert members of the IPH Executive Committee and ad hoc faculty, as needed. Researchers that want to access deidentified DNA samples must submit a Sample Request Form to the IPH. Upon approval, the investigator submitting the request will be contacted by the IPH to initiate the sample request protocol in collaboration with TPCL. TPCL will facilitate the distribution of deidentified DNA samples to the investigator. However, for identified or coded samples, TPCL will only provide samples to investigators who have a valid IRB approved project that specifies the use of ATLAS samples for their research. All researchers are required to submit their IRB approval letter to TPCL for review.

UCLA PIs will be charged a nominal fee for processing services. Please contact Dr. Clara Magyar - [email protected] for more details.
