• 1. 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.

• 2. dbGaP
• The database of Genotype and Phenotype (dbGaP) was developed to archive and distribute the results of studies that have investigated the interaction of genotype and phenotype. Such studies include genome-wide association studies, medical sequencing, molecular diagnostic assays, as well as association between genotype and non-clinical traits.

• 3. G2D: Candidate Genes to Inherited Diseases
• The Genes2Diseases server presents precomputed candidate genes for more than 600 genetically inherited diseases that have been mapped onto chromosomal regions without assignment of a particular gene.

• 4. Genetic Alliance – Disease InfoSearch
• Disease InfoSearch contains info on advocacy support groups related to specific genetic conditions, information about the clinical features of a wide number of genetic conditions, updates on management, treatment and more. Information is provided the advocacy organizations which form Genetic Alliance.

• 5. HGVbaseG2P: a Human Genome Variation and Genotype/Phenotype Database
• The Human Genome Variation database of Genotype-to-Phenotype information (HGVbaseG2P) provides a centralized compilation of summary level findings from genetic association studies, both large and small. They actively gather datasets from public domain projects, and encourage direct data submission from the community.

• 6. HGVS; Human Genome Variation Society's Variation Databases and Related sites
• The HGVS' list of variation databases includes SNP and locus specific databases. Users are encouraged to check the currency of databases when using them.

• 7. 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.

• 8. NIAID HIV Protein Interaction Project
• NCBI. The goal of this project is to provide scientists in the field of HIV/AIDS research a summary of known interactions of HIV-1 proteins with host cell proteins, other HIV-1 proteins, or proteins from disease organisms associated with HIV/AIDS. NOTE: This database has not been updated since 2007, but the formatted search links of NCBI databases retrieve up-to-date results.
