AD Knowledge Portal

AD Knowledge Portal aggregates and distributes genomic variant and transcriptomic datasets from the same individuals along with comprehensive metadata to support research into aging, dementia, and Alzheimer's disease.

Key Features:

• Paired Genomic and Transcriptomic Data: Provides genomic variant and transcriptomic datasets derived from the same individuals to enable integrative analyses.
• Data Discoverability: Enables search and retrieval of datasets based on sample- and study-level annotations related to aging and dementia research.
• Contextual Metadata: Supplies detailed annotations including diagnostic criteria and methodological details about sample preparation and data analysis.
• Programmatic Data Download: Supports bulk and automated data retrieval via a command-line client for integration into computational workflows.
• Metadata Integration: Facilitates merging of separate metadata sources into comprehensive files containing essential factors and covariates for downstream analyses.

Scientific Applications:

• Genetic Studies: Enables exploration of genetic variants associated with Alzheimer's disease for biomarker and target discovery.
• Transcriptomic Analysis: Supports analysis of gene expression patterns to investigate molecular pathways involved in disease progression.
• Epidemiological Research: Allows integration of diverse datasets to investigate risk factors and demographic trends related to aging and dementia.

Methodology:

Structured data curation with comprehensive metadata and annotations (study design, participant demographics, diagnostic criteria, technical methodologies), merging of metadata into integrated covariate files, and support for automated data retrieval via a command-line client.
