Gene

GC

GC makes vitamin D binding protein, which carries vitamin D metabolites in blood. Variants in this region are among the strongest genetic markers for total circulating 25-hydroxyvitamin D. For rs2282679, the reliable customer result is a small total-blood-vitamin-D tendency. The marker does not prove that a person has less binding protein, and it does not predict sun or supplement response.
