This looks nuts to me

I’m new to this and have been looking at reports (for daaaaays) and many genes in my vitamin absorption section have the standard two-letter code next to them - but in this panel, there are many that look like this:

MMACHC rs780329206 -/CCATCCCATGTGGACCCTG

I’m thrilled to be finding some answers with LiveWello, and would anyones input if they know what this means!
Thank you.
