The codon UGU codes for the amino acid Cysteine. The codon UGG codes for the amino acid Tryptophan. Therefore the mutation will cause the amino acid Cysteine to be replaced with Tryptophan. These amino acids are quite different, and the final shape of the protein could be changed as a result. This could affect the function of the protein.
A point mutation is a type of mutation in the DNA that leads to a single change in the amino acid sequence of the protein. This can involve the substitution of one nucleotide for another, resulting in the incorporation of a different amino acid into the protein sequence.
The amino acid sequence is shifted, and this kind of mutation is called a frame shift mutation. All of the amino acid sequence after the mutation will be changed, which will cause a change in shape of the protein, which will then probably result in a nonfunctional protein, since the shape of a protein determines its function.
A mutation in the third position of a codon (silent mutation) can result in the same amino acid being encoded due to the redundancy of the genetic code. Since multiple codons can code for the same amino acid, a mutation may not change the amino acid sequence despite occurring in the coding region of the gene.

The RNA sequence CUA codes for the amino acid leucine.
A synonymous mutation is a genetic mutation where a nucleotide change in the DNA sequence does not alter the amino acid sequence of the protein. This type of mutation occurs in the third position of a codon, which can still code for the same amino acid due to redundancy in the genetic code.
A point mutation could have no impact or it could be lethal. It depends on whether the mutation changes the amino acid sequence of a protein, or if it changes the amino acid at a critical location in the protein.
The neutral mutation does not change the amino acid coded for by the codon. A good example is the RNA codon that could be the CCA, CCC or the CCG.
