Targeting a cure

Our mission is to process and harmonize Alzheimer’s Disease genetic and genomic data to facilitate and expedite gene discovery and drug target identification.

Data Submission

NIAGADS guidelines and templates for data contribution to GCAD for harmonization with the Alzheimer’s Disease Sequencing Project dataset.

From raw to analysis-ready data

Whole-genome and whole-exome sequencing data are processed into CRAMs, gVCFs and then joint called into project level VCFs.

Collaborating with researchers around the world

GCAD is facilitating collaborations between cohorts and researchers studying neurodegenerative diseases from all over the world.

  • Creating the Largest Joint-Called Whole Exome Sequencing (WES) Dataset for Alzheimer’s Disease (AD) 

    Over the last 20 years, the technology for DNA sequencing has rapidly evolved, making it possible to sequence individual whole genomes on a large scale. But when trying to find the underlying genetic causes of disease, every sequence donated matters. How can the sequences generated using older technology be reused?…

  • ADSP Releases Additional 19K Whole Genomes via NIAGADS DSS

    On October 6, 2022, the Alzheimer’s Disease Sequencing Project (ADSP) released a new dataset comprised of 19,456 newly sequenced genomes together with joint genotype calls totaling 36,361 genomes with previously released genomes. The data release includes sequencing reads in the CRAM file format, individual sample genotype calls in the genomic…

  • ADSP releases quality-controlled whole-genome data on nearly 17,000 samples

    NIAGADS is pleased to announce the release of the Release 3 (R3) WGS ADSP quality-controlled joint genotype called pVCF containing 16,905 samples. Additionally, this release includes a quality-controlled X-chromosome pseudoautosomal region (PAR) pVCF containing 20,503 whole exomes from Release 2 (R2) as well as R3 individual-level VCF structural variant (SV)…
