What does the ">" symbol signify when interpreting genetic results?

In genetic nomenclature, the ">" is used to signify which allele is the non-risk allele and which allele is the elevated risk allele. 

• The non-risk allele is to the left of the ">" 
• The elevated risk allele is to the right of the ">"
• non-risk > elevated risk

In the example of MTHFR 677 C>T, C is the non-risk allele and the T is the elevated risk allele.
