How to: Find human variations associated with a phenotype or disease (clinical association)
Starting with a disease or phenotype in...
PubMed
- On the PubMed homepage, search with a disease or phenotype name and additional terms to find variations that have been identified as being associated with or causative for the phenotype, for example: humans[MeSH terms] AND asthma AND (causative OR associated OR association) AND (variation OR variant OR mutant).
- Alternatively, on the PubMed Clinical Queries page you can search for medical genetics publications. Perform a search on this page and link to "See all" records at the bottom of the Medical Genetics column (on the right).
ClinVar
- On the ClinVar homepage, enter a gene, HGVS expresssion, identifier from dbSNP or dbVar, MIM number, MedGen Concept ID, or phenotype name by typing in the search box.
- Click the Search button.
- Filter the results using the Filter Sidebar at the left.
- The result set will provide summary data of the submitted clinical interpretation(s), with details of interpretations from each submitter available from the details section.
dbVar
- On the dbVar homepage, enter a disease or phenotype name by typing in the search box.
- Click Limits under the search bar.
- In the “Clinical interpretation" section, select "Pathogenic" and "Uncertain Significance: likely pathogenic" by clicking the check boxes.
- Click the Search button.
- Click the “Variant” filter at the upper right (to exclude the report of the study registered in dbVar).
- Click any nsv identifier for more information and links to other NCBI resources.
PheGenI
- On the PheGenI homepage, select a Category or Trait name in the "Phenotype Selection" section. Selecting the "Category" first will limit the list of Traits to those available for the particular MeSH Category.
- To limit the retrieval of data by P-Value of the association report, enter the exponent in the box.
- Click the Search button.
- Click "Association Results" in the Search results section to review the data in the Association Results table to evaluate the evidence for the association between a variation and the measured trait. For more and related information, click links to the "Gene", "PubMed", or "Source" databases.
- Alternatively, click "Genes" in the Search results section to review the genes associated with the phenotype selection. Click a Location link to see an interactive graphical sequence viewer display for the selected gene.
Gene and linking to ClinVar
- On the Gene database homepage, enter a disease or phenotype name in search box and click "Search".
-
If you want to review results for multiple genes as a group:
- Complete the check box for the records of interest
- Go to the "Find related data" section in the column at the right
- Pick ClinVar from the menu
- Press Find items
- The result set will provide summary data of the submitted clinical interpretation(s) for the selected gene(s), with details of interpretations from each submitter available from the details section.
-
If you want to review results for only one gene:
- Display the gene of interest by clicking on the title
- Click on Variation in the Table of contents at the top of the column at the right
- Follow the links to ClinVar
- The result set will provide summary data of the submitted clinical interpretation(s) for the selected gene, with details of interpretations from each submitter available from the details section.
