• 1. Blood Group Antigen Gene Mutation Database (dbRBC)
• NCBI. The Blood Group Antigen Gene Mutation Database (dbRBC) documents variations in genes that directly or indirectly affect blood groups. It thus is a locus-specific mutation database (LSDB) that covers multiple genes.

• 2. BTKbase: X-linked agammaglobulinemia (XLA) | Main page |
• Search for information on defects in the Bruton tyrosine kinase (BTK) gene, which causes agammaglobulinemia (XLA). USE WITH CAUTION: DATABASE HAS NOT BEEN UPDATED SINCE 2008.

• 3. CarpeDB: A Comprehensive Database on the Genetics of Epilepsy
• CarpeDB serves as a novel source for epilepsy researchers by featuring scores of "epilepsy genes" and associated publications in one locus. Furthermore, multiple genes implicated in epilepsy are also implicated in other human disorders.

• 4. DG-CST Database
• A collection of conserved sequence elements, identified by a systematic genomic sequence comparison between a set of human genes involved in the pathogenesis of genetic disorders and their murine (mouse) counterparts.

• 5. HGMD®: Human Genome Mutation Database
• The HGMD is a comprehensive listing of gene mutations. Users must register for the most current version, which is free to academic users.

• 6. MutDB
• The goal of MutDB is to annotate human variation data with protein structural information and other functionally relevant information, if available. The mutations are organized by gene.
