What type of mutation is this?

What type of mutation would an insertion mutation in an mRNA sequence that turns a codon into a stop codon be called?

Example:

mRNA: AUG AAA CCC UAU CGG ...

Insertion of G between UA and U, so:Mutated mRNA: AUG AAA CCC UAG.  (UAG codes for STOP)Would this be a nonsense substitution mutation or an insertion frameshift mutation?

    So...your question is "does this INSERTION count as a SUBSTITUTION or an INSERTION?"

    Yeah, that's a headscratcher, that one is.
