Abigail was referred to a genetics team to help her and her mom navigate the world of specialty formulas and medications. Through trial and error, they were able to determine how much protein Abigail’s body could handle. After a few years of treatment, they were the first family the clinic staff thought of when a new medication — sapropterin (Kuvan) — became available to treat PKU.
The medication worked; Abigail’s Phe levels were low, indicating she has hyperphenylalaninemia, a mild form of PKU. Abigail explains, “Since my blood work is in a good range and I respond to my medication, I now have an unrestricted diet and do not need to eat or drink medical foods or formula for nutrition.
My diet allows me to have all the nutrition I need.” She still battles some symptoms related to PKU such as headaches, side effects from medication, and a learning disability. But that has not stopped Abigail from becoming a fierce advocate for others with rare diseases, especially PKU.
