• 1. CGAP and CGCI - Cancer Genome Anatomy Project & Cancer Genome Characterization Initiative
• The goal of the NCI's Cancer Genome Anatomy Project is to determine the gene expression profiles of normal, precancer, and cancer cells, leading eventually to improved detection, diagnosis, and treatment for the patient. Includes high-quality histology photos of tissue expression.

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

• 4. 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.

• 5. 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.
