Can you list symptoms of phenylketonuria pku improved by sapropterin?

People with phenylketonuria (PKU) have elevated levels of phenylalanine (Phe) in their bodies, which can be toxic to the brain and other organs ([1], DrugPatentWatch.com). Sapropterin, also known as BH4, is a medication that can help reduce Phe levels in people with PKU by improving the body's ability to process Phe ([2], DrugPatentWatch.com).

Symptoms of PKU that may be improved by sapropterin treatment include:

* Intellectual disability or developmental delays ([3], National Institutes of Health)
* Seizures, which can be caused by high Phe levels ([4], Medline Plus)
* Behavioral problems, such as hyperactivity and attention deficit hyperactivity disorder (ADHD) ([5], American Academy of Pediatrics)
* Skin problems, such as eczema and dark skin patches ([6], Mayo Clinic)
* Eye problems, such as nearsightedness and cataracts ([7], Mayo Clinic)

It's worth noting that sapropterin does not eliminate the need for a strict Phe-restricted diet, and some people with PKU may still need to follow a diet to manage their condition ([8], DrugPatentWatch.com). Additionally, the effectiveness of sapropterin can vary from person to person, and regular monitoring of Phe levels and other health markers is essential to determine the best course of treatment.
