Beta Ketothiolase Deficiency (BKT, BKD or KUD)
Our first child Poppy was born in November 2009, punctually on her due date. As a resident of California she underwent expanded newborn screening when she was born, but the test came back negative. We proceeded to live the typical life of a family with a new baby, with all the usual joys and hardships, not knowing that Poppy has beta-ketothiolase deficiency (BKT or BKD).
