silent mutations - (Oct/05/2012 )

Is there any way in which this type of mutation can change the phenotype of an individual....

I think yes.
A silent mutation in a gene doesn't change the amino acid of the protein, but you have to consider also the regulation mechanisms associated with the gene (the mutation may cause for example a different splicing or a different regulation of the expression of the gene).
Maybe you can look for some examples in pubmed.
