I have been having an interesting time looking at the Solute Transporters (SLC) of all the 15 gene samples I have with people of varying levels of disease. I have noticed a trend, that the number of SLC gene SNPs that a persons has with a frequency of under 20% is correlated with health. Those with under 20 have very few health complaints. Those with 40 or more start showing signs of debilitating health. The sickest person I have genes for, a 26 year old female on disability for several degenerative diseases and mental health issues, has over 80 SLC SNPs under 20%! It is acknowledged they play a role in health http://www.ncbi.nlm.nih.gov/pubmed/23506860 "The field of transport biology has steadily grown over the past decade and is now recognized as playing an important role in manifestation and treatment of disease." If you have you promethease report you can count these simply by searching for SLC, set the sort function to "Frequency", and increase the "Allow" number to 80. Then just scroll through and count. I made a video of how to do this here: If you want to check what your SLC gene SNPs might signal you can check what the the specific gene does here: http://www.bioparadigms.org/slc/intro.htm or http://www.genenames.org/genefamilies/SLC Here are my SNPs that are under 20% SLC28A2 Sodium/nucleoside SLC6A4 Serotonin SLC6A1 GABA SLC5A1 Sodium/Glucose SLC23A2 Sodium/Ascorbate SLC40A1 Iron SLC2A9 Urate Fructose SLC35F1 Drug Metabolite SLC45A3 Transmembrane Lipid?
