Boyfriend’s studying for his medical boards, and he just called me up to tell me that he’d made up the greatest mnemonic ever.
The CAG is hunting 4 cylons.
Hunting = Huntington’s Disease, CAG = a CAG trinucleotide repeat, 4 = chromosome 4.
Because Huntington’s Disease is caused by having multiple CAG repeats on the 4th chromosome.
Now whenever someone brings up Huntington’s, you can nod your head and act all sage and say, “Yeah, isn’t it scary just how much damage a CAG repeat can do? It’s on the 4th chromosome for Huntington’s, isn’t it?” and they will think you’re a complete nerd GENIUS.
