In mature mRNA, there is a start codon (AUG) that instructs ribosome to begin translation. Thereafter, every 3 bases are read as a "code word" calling for a particular amino acid to enlogate the polypeptide chain or to STOP and release the polypeptide. If 1 or 2 nucleotides are deleted or inserted into this sequence, it causes the reading frame to shift. This usually results in misreading of the sequence here is an example:
AUG - AGC - ACC - TAA - GGG - etc. (if we delete the first C we get....)
AUG - AGA - CCT - AAG - GG ( this is obviously not going to code for the same amino acid sequence)

Yes, a point mutation can result in a frameshift mutation if it occurs in a coding region of a gene and disrupts the reading frame of the genetic code.
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.
A frameshift mutation in the CARD15 gene
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.
nonsense mutation, missense mutation, frameshift muation, deletion or addition mutation
frameshift mutation: deletion
frameshift mutation, which alters the reading frame of the gene. This can result in a nonfunctional or altered protein being produced.
