TogoVar

TogoVar aggregates allele frequency data and variant annotations from reanalyzed individual-level genome sequence data in the Japanese Genotype-phenotype Archive (JGA) and public datasets to support genetic and population-genetic research in Japanese and comparative populations.

Key Features:

• Integration of allele frequencies: Allele frequencies are derived from a reanalysis scheme of individual-level genome sequence data stored in the Japanese Genotype-phenotype Archive (JGA) and from public datasets.
• Dynamic sample size expansion: The database sample size increases as additional genomic data from Japanese individuals are deposited into JGA.
• Cross-population comparison: Public datasets from Japanese and non-Japanese populations are incorporated to enable allele frequency comparisons across ethnic groups.
• Permanent variant identification: Each detected variant is assigned a unique TogoVar ID to provide a stable identifier for tracking and referencing.
• Comprehensive annotations: Variants are annotated with molecular consequences, pathogenicity information, and links to relevant literature.

Scientific Applications:

• Population genetics: Provides allele frequency data that reflect genetic diversity within Japanese populations for population-genetic analyses.
• Identification of population-specific markers: Supports discovery and characterization of genetic markers specific to Japanese individuals.
• Disease variant analysis: Aids studies aimed at understanding the genetic basis of diseases prevalent in Japanese populations using allele frequencies and pathogenicity annotations.
• Comparative genomics: Enables cross-population comparisons of allele frequencies between Japanese and non-Japanese datasets.
• Personalized medicine research: Contributes population-specific variant data and annotations that inform ethnicity-aware approaches in precision medicine.

Methodology:

Reanalysis of individual-level genome sequence data stored in JGA; integration of public datasets from Japanese and non-Japanese populations to calculate allele frequencies; assignment of unique TogoVar IDs to variants; annotation of molecular consequences, pathogenicity, and relevant literature; publication of allele frequencies.
