A mutation can significantly impact the function of the protein produced by a gene, and each type of mutation listed can alter the protein in different ways.

A deletion mutation involves the removal of one or more nucleotides from the DNA sequence. This kind of mutation can lead to a frameshift, where the reading frame of the gene is altered. As a result, the entire amino acid sequence downstream of the mutation can change, potentially leading to a nonfunctional protein.

An inversion mutation occurs when a segment of DNA is reversed within the chromosome. This can disrupt the order of genes or regulatory elements, which might affect how the gene is expressed or how the protein is folded and functions.

A translocation mutation happens when a segment of DNA from one chromosome is transferred to another chromosome. This can cause misregulation of gene expression and can also result in a fusion protein that has altered functionality, making the protein behave differently than intended.

Since all these types of mutations can lead to significant changes in the protein's structure or function, the most comprehensive and accurate answer is that all of these mutations could likely result in a change in the function of the protein produced by a gene.
