Hello, Sterling's app pointed out these two SNPs for me (rs55776826 was also in the 10% database for the Java app, but didn't show up in snpedia so hadn't noticed it that way): GAMT rs17851582 A AG +/- GAMT rs55776826 T TT +/+ No idea what it was until I read http://ghr.nlm.nih.gov/gene/GAMT: So apparently poor GAMT could screw over your natural creatine. Is that correct? Does anyone else have these and looked into them? These mutations don't seem too popular: https://opensnp.org/snps/rs17851582 - AG 15% https://opensnp.org/snps/rs55776826 - TT 2% This raises the obvious question, should I try supplementing with creatine??? I've always been wary of sports supplements that aren't simple amino acids or whey. This page describes creatine defiency syndromes: http://www.ncbi.nlm.nih.gov/books/NBK3794/ However I have no idea what would constitute an inefficiency in producing creatine vs a clinical deficiency. Has anyone read the sports research?
