Background: Primary Hyperoxaluria Type 1 (PH1) is an inborn error of metabolism caused by mutations in the AGXT gene. which encodes for the hepatocyte-specific enzyme alanine: glyoxylate aminotransferase (AGT). AGT catalyzes the conversion of glyoxylate to glycine in the peroxisome and prevents the build-up of oxalate which occurs in PH1. This causes nephrocalcinosis. https://www.roneverhart.com/M-M-s-Speckled-Easter-Eggs-Candy-10-13-Ounce-Bag/
