There are 5 different disorders that result in galactosemia differentiated into three main types. The worst is the Classic form and there are over 180 different mutations associated with this form.
The GALT gene is modified by substitution is these examples.
The most common one in Caucasian is a single substitution of arginine for glutamine at position 188 on the protein.
Another mutation that occurs almost exclusively in individuals of African decent is
a single substitution of leucine for serine at position 135.
A frameshift mutation completely changes the genetic code from the point of the mutation, so the protein made as a result of the mutation would have the incorrect structure and would not function as it should.

Referring to the frameshift mutation in genes, frameshift is where number of nucleotides inserted or deleted is not a multiple of three, resulting in every codon after the point of insertion or deletion is read incorrectly during translation.
Insertion
frameshift- deletion and insertion point mutation- sustitution
From another angle: beneficial and detrimental.
Substitution is not ever a frame shift mutation. However, insertion, point mutation, and deletion are all examples of a frame shift mutation.
why is frameshift mutation more damanging than a substitution
A frameshift mutation completely changes the genetic code from the point of the mutation, so the protein made as a result of the mutation would have the incorrect structure and would not function as it should.
frameshift mutation
Insertion, Deletion and Frameshift mutation. These are the 3 basic types of mutation, however, there are other types of mutations: substitution, translocation, duplication, inversion, transversion and transition.
An insertion/deletion event.
Missense mutation Nonsense mutation Frameshift insertion Frameshift deletion All may cause antibiotic resistance in bacteria
Frameshift mutations MAY change every amino acid that follows the point of mutation.

Three types of gene mutations are substitution, insertion, and deletion. Another gene mutation would be frame shift. All these mutations can cause deformities of the gene.
