How many inherited diseases have a known phenotype but no corresponding sequence data?
The OMIM database does not track this number specifically. However, OMIM uses the percent sign (%) prefix for records that describe a “mendelian phenotype or locus, molecular basis unknown”. To see the number of records whose MIM number has that prefix, you can either (a) see the OMIM statistics page, or (b) activate the check box for that prefix on the OMIM Limits page and press the Go button. Both approaches display the number of records in the subset and enable you to retrieve the records. Entrez Gene also enables you to retrieve human genes for which (a) we have no sequence data, or (b) for which only a phenotype is known. To do this, follow the search strategies below. However, there is no way to currently limit Entrez Gene searches to only disease genes. • to retrieve human genes for which we do not yet have sequence data: human[orgn] NOT gene_nucleotide[filter] That will retrieve database records for human genes that do not have links to nucleotide sequence records.
