WebOnce the folates pass through the FOLR genes (folate receptor genes), folates get converted to Dihydrofolate (DHF) via the DHFR genes (in Red) above. In addition, the gene DHFR, which is part of the folate family of genes (MTHFR), is directly connected to the folate receptor, that feeds the biopterin cycle in your brain.
