Tool for getting every CHROM_POS_REF_ALT that will produce specific point mutation

Question

[sviatoslav.kendall]

I have a list of point mutations formatted like this:

BRAF_V600E

...and I want to compile a list of coordinates and base changes formatted like this:

chr7_140453136_A_T

...for a given build (in this case HG19). Does such a tool exist already?
