Symptoma

Phenylalanine Increased

Blood Phenylalanine Increased

GTP cyclohydrolase deficiency presents with an autosomal dominant and an autosomal recessive form. [invitae.com]

The clinical presentation is similar to that observed with PTS deficiency. [pediatricmotordisorders.org]

All other enzymes present in Plasmodium falciparum phenylalanine and tyrosine metabolism pathway are also present in T. gondii and N. caninum. [llamp.net]

BH4 is ubiquitous and is likely present in all cells and tissues but current knowledge of the regulatory mechanism of BH4 in the brain is far from complete [14]. [journals.plos.org]

No, but both diseases present with elevated blood phenylalanine levels. In addition BH4 -deficient patients present with deficiency of catecholamines and serotonin in the brain. [excemed.org]

  • Developmental Delay

    The initial presentation includes abnormal movements and developmental delay in the first few months of life. [invitae.com]

    delay despite a phenylalanine-restricted diet. [pediatricmotordisorders.org]

    delay, seizures, ataxia Treatment: Dietary phenylalanine and tyrosine restriction, ascorbate supplementation 4-Hydroxyphenylpyruvate dioxygenase Not genetic Biochemical profile: Elevated plasma phenylalanine and tyrosine Clinical features: Usually occurring [msdmanuals.com]

    Increased Risk During Pregnancy According to an abstract from the American Academy of Pediatrics (AAP), elevated levels of phenylalanine -- even mildly elevated levels -- during pregnancy may increase the risk of developmental delays and growth delays [vitamins.lovetoknow.com]

    Abstract Elevated maternal phenylalanine concentrations during pregnancy are teratogenic and may result in growth retardation, microcephaly, significant developmental delays, and birth defects in the offspring of women with poorly controlled phenylketonuria [pediatrics.aappublications.org]

  • Progressive Mental Retardation

    Untreated individuals have very fair hair, eczema, a mousy odor of the urine and skin, and progressive mental retardation. Treatment consists of a diet low in phenylalanine. [medical-dictionary.thefreedictionary.com]

  • Eye Movements Abnormal

    Such patients have severe global developmental impairment, marked hypotonia of the trunk and axial muscles, eye movement abnormalities, limb hypertonia, convulsions and autonomic symptoms including temperature dysregulation, excessive diaphoresis and [pediatricmotordisorders.org]

  • Fear

    Too much, as you mentioned, is associated with fear, anxiety, stress, and at extreme levels perhaps stroke, etc. [bluelight.org]

Treatment involves oral L-dopa replacement and BH4 supplementation. PTS deficiency presents with severe and attenuated forms. [invitae.com]

Without folinic acid to restore methyltetrahydrofolate status in the CNS, these patients can have progressive calcification of the basal ganglia and subcortical regions, despite treatment with BH4 and neurotransmitter precursors. [pediatricmotordisorders.org]

Patients with the peripheral form have an excellent prognosis for normal neurologic development, provided the hyperphenylalaninemia is corrected by diet or BH4 administration. [pediatricmotordisorders.org]

The attenuated form is considered peripheral and has an excellent prognosis with treatment that includes supplemental BH4 and dietary phenylalanine restriction. [invitae.com]

Prognosis Prognosis is excellent for normal development when treated as indicated. Patient Education Teach patients and parents about proper diet. Children should participate in their dietary planning as soon as they have that ability. [emedicine.medscape.com]

Prognosis Early newborn screening, careful monitoring, and a life-long strict dietary management can help PKU patients to live normal, healthy, and long lives. Resources Books Brust, John C. M. [medical-dictionary.thefreedictionary.com]

Counseling and Follow-up With early diagnosis of PKU and institution of the phenylalanine-restricted diet, the prognosis for intellectual development in affected children is excellent. [aafp.org]
