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? And can researchers analyze sequence data generated in different locations, on different platforms, using different technologies? These are becoming increasingly important issues for the research community to address. The Genome Center for Alzheimer’s Disease ( GCAD ) tackled these...
We are thrilled to announce the release of 15 much-anticipated genotyping array datasets from participants recruited from the Alzheimer's Disease Research Centers (ADRC)! These datasets, ADC1 through ADC15 , are now available on the NIAGADS Data Sharing Service (DSS). DNA was prepared by the National Centralized Repository for Alzheimer’s Disease and Related Dementias (NCRAD) and phenotypes were provided by the National Alzheimer’s Coordinating Center (NACC) . Collection and harmonization were facilitated by the Alzheimer's Disease Genetics Consortium (ADGC) , which included rigorous quality...
A major challenge facing researchers today is the cleanup and harmonization of data for use in their work. As datasets get larger and the types of outputs continue to grow, this problem will continue to grow exponentially. Manually cleaning this data can be time consuming and prone to human error. Addressing these needs for cleanup and harmonization of functional genomics data is how hipFG (Harmonization and Integration Pipeline for Functional Genomics ) , a high-throughput harmonization and integration pipeline, was born. We sat down with Jeffrey Cifello, lead code developer for the hipFG...
A new version of ng00067, the ADSP Umbrella Dataset is available on NIAGADS DSS . The ng00067.v11 release consists of: The round 2 harmonized phenotypes from the Phenotype Harmonization Consortium, which includes a subset of harmonized, ADSP-sequenced participant data from the following studies: Anti-Amyloid Treatment in Asymptomatic Alzheimer’s study (A4 Study) Adult Changes in Thought (ACT) Study Alzheimer’s Disease Neuroimaging Initiative (ADNI) Estudio Familiar de Influencia Genetica en Alzheimer (EFIGA) Memory & Aging Project at Knight Alzheimer’s Disease Research Center (MAP at...
The ADSP has recently unveiled an updated version of the dataset (ng00067.v10) that encompasses valuable genetic information. This release comprises two key components: 1. A quality-controlled project-level Variant Call Format (pVCF) file for bi-allelic autosomes derived from the R4 whole genome sequencing (WGS) dataset, encompassing 36,361 samples. 2. Individual-level structural variant calls generated by two callers, Manta and Smoove, specifically for the new samples introduced in R4 (n=19,451). Furthermore, the R4 quality-controlled pVCF offers compact and compact filtered versions,...
