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.
A one base left out mutation is called a deletion mutation. This type of mutation involves the loss of one or more nucleotides from a DNA sequence, which can lead to a frameshift mutation if not in multiples of three.
If one nucleotide is replaced by another, it is called a point mutation. This type of mutation involves a change in a single nucleotide within the DNA sequence.
The three different types of mutation are substitution, insertion, and deletion. They differ because deletion is missing a base, insertion has a base that was added, and substitution has a base that has been replaced.
A point mutation is not a frameshift mutation. Point mutations involve changes in a single nucleotide base, while frameshift mutations involve the insertion or deletion of nucleotide bases, causing a shift in the reading frame of the genetic code.
From another angle: beneficial and detrimental.
A point mutation is never a frameshift mutation because it involves the substitution of a single nucleotide for another rather than the insertion or deletion of nucleotides that would disrupt the reading frame of a gene.

SCID can be caused by a variety of genetic mutations, including both frameshift and point mutations. Frameshift mutations involve the insertion or deletion of nucleotides that shifts the reading frame of a gene, while point mutations involve the substitution of a single nucleotide.
A frameshift mutation alters the reading frame of the genetic code, causing all amino acids downstream of the mutation to be incorrect. This can lead to a nonfunctional or drastically altered protein. A substitution mutation only changes one amino acid, which may have a milder effect on protein function.

A frameshift mutation
A frameshift mutation, where an insertion or deletion of nucleotides causes a shift in the reading frame of the genetic code, can change every amino acid that follows the point of mutation. This can have dramatic effects on the resulting protein's structure and function.
