If an A (Adenine) were swapped for a T (Thymine) it will lead to A TRANSVERSION TYPE OF POINT MUTATION.

Replacement of an A with a T is a transversion type of point mutation because in transversion the purine is replaced with a pyrimidine. Since in this case only one nucleotide is replaced, it is a point mutation.
