mtDB: Human Mitochondrial Genome Database, a resource for population genetics and medical sciences

Area of Science:

• Genetics
• Molecular Biology
• Bioinformatics

Background:

• The mitochondrial genome encodes essential peptides for cellular energy.
• Mitochondrial genes exhibit high polymorphism, making variation cataloging crucial for medical and population genetics.
• The Human Mitochondrial Genome Database (mtDB) has been a key resource for human mitochondrial genome data since the early 2000s.

Purpose of the Study:

• To update and expand the mtDB with an increased number of complete human mitochondrial genome sequences.
• To provide a web-based platform for accessing human whole genome and complete coding region sequences.
• To facilitate the search and download of specific mitochondrial polymorphisms and haplotype information.

Main Methods:

• Compilation of published complete human mitochondrial genome sequences.
• Development of a web-based database interface for data retrieval and analysis.
• Implementation of search functions for specific polymorphisms and haplotype analysis.

Main Results:

• As of August 2005, the database contained 2104 sequences (1544 complete genomes, 560 coding regions).
• A comprehensive list of 3311 mitochondrial polymorphisms is available.
• New features include haplotype search and variant-specific sequence identification/download.

Conclusions:

• The expanded mtDB serves as a vital resource for researchers studying mitochondrial dysfunction and human population genetics.
• The database's search and download capabilities enhance the study of mitochondrial DNA variation.
• Continued updates and feature expansions of mtDB support ongoing genetic research.
