To search for silent mutations for your protein in dbSNP it is useful to filter the results already in the query. This can be done with a simple concatenation of restraints which are connected with the operator "AND".

An example query of how to search for SNPs in the PAH gene in human which are silent could be:

  • "synonymous-codon"[Function_Class] AND PAH[GENE] AND "human"[ORGN] AND "snp"[SNP_CLASS]

To make this example work for your protein just replace PAH by your gene identifier.
