A regulatory mutation is one that occurs in the promoter or operator region of a gene or set of genes and affects the expression of the downstream genes without affecting the amino acid sequences of the gene products.

A mutation
In the DNA, the sequence of nucleotides determines how proteins are built, with each segment of three nucleotides encoding a single amino acid. When one nucleotide is inserted into the sequence, the whole sequence shifts, and all the triples are changed completely, which can cause detrimental mutations.
Sorry to burst the persons bubble that said frameshift mutation but its wrong. Point mutation-gene mutation involving changes in one or a few nucleotides. point mutation
Point Mutation- a type of gene mutation in which only a single nucleotide in a gene has been changed.
When a mutation occurs outside a gene, it is referred to as a "regulatory mutation" or "non-coding mutation." These mutations can affect gene expression by altering regulatory elements such as promoters, enhancers, or silencers, which control when and how much a gene is expressed. Although they do not change the protein-coding sequence, they can still have significant effects on an organism's phenotype.
The location of the mutation within the genome, the type of mutation (e.g., missense, frameshift), and its effect on gene function or protein structure typically determine the magnitude of a mutation's effect. Additionally, the degree to which the mutation disrupts important cellular processes or regulatory mechanisms can also influence its impact.
A point mutation is when a single nucleotide switches from G to C or from A to T, or when a single nucleotide is deleted or inserted. It's unlikely for any single mutation to have a significant effect, but the effects that could occur could be anything, ranging from eliminating or altering protein synthesis of a particular protein to altering the regulatory function of a stretch of DNA and thereby affecting the embryological development of an organism.

A frameshift mutation is likely to affect the largest number of proteins produced by an organism. This type of mutation occurs when nucleotides are inserted or deleted from the DNA sequence, altering the reading frame of the gene. Consequently, this can lead to changes in the entire amino acid sequence downstream of the mutation, potentially resulting in nonfunctional proteins or the production of truncated proteins. Such widespread effects can disrupt multiple proteins if the mutation occurs in a key regulatory region or affects multiple genes.

A mutation
A mutation in a gene involves a change in the sequence of DNA bases, which can occur through substitutions, insertions, or deletions. This alteration can affect the amino acid sequence of the protein encoded by the gene, potentially altering its structure and function. Depending on the nature of the mutation, it can lead to beneficial, neutral, or harmful effects on the organism. In some cases, mutations can also disrupt regulatory elements, affecting gene expression.
