A deletion mutation occurs when a wrinkle forms on the DNA template strand and subsequently causes a nucleotide to be omitted from the replicated strand.
It is a type of frameshift mutation characterized by the loss of one or more nucleotides from the segment of DNA. Example of deletion mutation is DiGeorge syndrome.
