How do these sound to you?

I am choosing an acronym for a new medical technology. So far I have few variants:
SeqLA  therapy or SeqLAT - sequential laser activation (of genes).
SEMGA therapy or SEMGAT - sequential electromagentic gene activation
SeLGA therapy or SelGAT- Sequential Laser Gene Activation
SeqNA therapy or SeqNAT - sequential nucleotide activation
SNAT - sequential nucleotide activation therapy
SANAT - sequentially activated nucleic acid therapy

So far I like SEMGA most. How do these names sound to a native English ear? What do you think?

P.S. OK! Lets drop SEMGA! How about the rest?
