If you only did the normal 23 and me test, you weren't fully sequenced. Just a tiny subset. Since most phenotypes are in fact caused by large numbers of mutations, each acting in a non-linear (non-additive) way, just knowing this SNP doesn't really provide that much information (except if the specific allele is highly penetrant, which seems unlikely in this case).
