An rsID such as rs1815739 is the reference number dbSNP assigns to one position in the genome where people commonly differ by a single letter. Raw data exports from 23andMe and AncestryDNA list your two alleles at that position as a genotype - for this marker one of CC, CT, TT. The order of the two letters carries no meaning, so CT and its reverse are the same genotype.
Alleles on this page are written on the forward (plus) strand, matching how consumer raw files report them. Other references sometimes describe the same variant on the opposite strand, which swaps A↔T and C↔G - see why the same variant can look different. The associations below are educational summaries of published research; they are not diagnoses, and the effect of any single SNP is usually modest.
