The risk of adverse outcome varies based on the degree of PAH deficiency. Without effective therapy, most individuals with severe PAH deficiency, known as classic PKU, develop profound and irreversible intellectual disability. Affected individuals on an unrestricted diet who have phenylalanine levels above normal but below 1,200 µmol/L (20 mg/dL) are at much lower risk for impaired cognitive development in the absence of treatment." /><meta name="robots" content="index,nofollow,noarchive" />

The risk of adverse outcome varies based on the degree of PAH deficiency. Without effective therapy, most individuals with severe PAH deficiency, known as classic PKU, develop profound and irreversible intellectual disability. Affected individuals on an unrestricted diet who have phenylalanine levels above normal but below 1,200 μmol/L (20 mg/dL) are at much lower risk for impaired cognitive development in the absence of treatment. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</div><div class="spaceAbove"><strong>Full text of <i>GeneReview</i> (by section):</strong><br /><a class="medgenPMinfo" href="/books/NBK1504#pku.Summary" target="NBK1504">Summary</a>  |  <a class="medgenPMinfo" href="/books/NBK1504#pku.Diagnosis" target="NBK1504">Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1504#pku.Clinical_Characteristics" target="NBK1504">Clinical Characteristics</a>  |  <a class="medgenPMinfo" href="/books/NBK1504#pku.Genetically_Related_Allelic_Disorder" target="NBK1504">Genetically Related (Allelic) Disorders</a>  |  <a class="medgenPMinfo" href="/books/NBK1504#pku.Differential_Diagnosis" target="NBK1504">Differential Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1504#pku.Management" target="NBK1504">Management</a>  |  <a class="medgenPMinfo" href="/books/NBK1504#pku.Genetic_Counseling" target="NBK1504">Genetic Counseling</a>  |  <a class="medgenPMinfo" href="/books/NBK1504#pku.Resources" target="NBK1504">Resources</a>  |  <a class="medgenPMinfo" href="/books/NBK1504#pku.Molecular_Genetics" target="NBK1504">Molecular Genetics</a>  |  <a class="medgenPMinfo" href="/books/NBK1504#pku.References" target="NBK1504">References</a>  |  <a class="medgenPMinfo" href="/books/NBK1504#pku.Chapter_Notes" target="NBK1504">Chapter Notes</a></div><div class="spaceAbove"><strong>Authors:</strong><br />

<div class="portlet_content ln"><div class="mgSection"><strong>From OMIM</strong><br />Phenylketonuria (PKU) is an autosomal recessive inborn error of metabolism resulting from a deficiency of phenylalanine hydroxylase (PAH; 612349), an enzyme that catalyzes the hydroxylation of phenylalanine to tyrosine, the rate-limiting step in phenylalanine catabolism. If undiagnosed and untreated, phenylketonuria can result in impaired postnatal cognitive development resulting from a neurotoxic effect of hyperphenylalaninemia (Zurfluh et al., 2008).&#13;

<div class="spaceAbove">Attention-deficit/hyperactivity disorder (ADHD) is a behavioral disorder that typically begins in childhood and is characterized by a short attention span (inattention), an inability to be calm and stay still (hyperactivity), and poor impulse control (impulsivity). Some people with ADHD have problems with only inattention or with hyperactivity and impulsivity, but most have problems related to all three features.\n\nIn people with ADHD, the characteristic behaviors are frequent and severe enough to interfere with the activities of daily living such as school, work, and relationships with others. Because of an inability to stay focused on tasks, people with inattention may be easily distracted, forgetful, avoid tasks that require sustained attention, have difficulty organizing tasks, or frequently lose items.\n\nHyperactivity is usually shown by frequent movement. Individuals with this feature often fidget or tap their foot when seated, leave their seat when it is inappropriate to do so (such as in the classroom), or talk a lot and interrupt others.\n\nImpulsivity can result in hasty actions without thought for the consequences. Individuals with poor impulse control may have difficulty waiting for their turn, deferring to others, or considering their actions before acting.\n\nIn most affected individuals, ADHD continues throughout life, but in about one-third of individuals, signs and symptoms of ADHD go away by adulthood.\n\nMore than two-thirds of all individuals with ADHD have additional conditions, including insomnia, mood or anxiety disorders, learning disorders, or substance use disorders. Affected individuals may also have autism spectrum disorder, which is characterized by impaired communication and social interaction, or Tourette syndrome, which is a disorder characterized by repetitive and involuntary movements or noises called tics.</div>
