Probaby the phrase you are using is not indexed in Entrez SNP i.e. the SNP has not been assigned the 'locus-region' functional annotation.
I think earlier u asked for another online source for SNP analysis. Here is 1. Go to: 1. http://www.ensembl.org 2. Enter "CFTR" in search term. 3. Click entry u want. 4. Click the Transcript ID u want to choose. 5. Select: Transcription-based analysis>Protein Infromation>Variations 6. You can view the individual description of every SNP just by clicking.
