• 1. 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.

• 2. Genes and disease
• NCBI online resource on genetic basis of disease

• 3. 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.

• 4. OMIM
• Online Mendelian Inheritance in Man (OMIM) is a continuously updated catalog of human genes and genetic disorders. OMIM focuses primarily on inherited, or heritable, genetic diseases. It is also considered to be a phenotypic companion to the human genome project.
