Total 27 clinical symptoms reported for Neutral 1 amino acid transport defect  Very Frequent (9)Occasional (11)Frequent (7)

Abnormal urinary color	An abnormal color of the urine, that is, the color of the urine appears different from the usual straw-yellow color.   Synonyms:Abnormal urinary color; Abnormal urine color	Very frequent
Anxiety	Intense feelings of nervousness, tension, or panic often arise in response to interpersonal stresses. There is worry about the negative effects of past unpleasant experiences and future negative possibilities. Individuals may feel fearful, apprehensive, or threatened by uncertainty, and they may also have fears of falling apart or losing control.   Synonyms:Anxiety; Anxiousness; Excessive, persistent worry and fear	Very frequent
Ataxia	Cerebellar ataxia refers to ataxia due to dysfunction of the cerebellum. This causes a variety of elementary neurological deficits including asynergy (lack of coordination between muscles, limbs and joints), dysmetria (lack of ability to judge distances that can lead to under- or overshoot in grasping movements), and dysdiadochokinesia (inability to perform rapid movements requiring antagonizing muscle groups to be switched on and off repeatedly).   Synonyms:Cerebellar ataxia	Very frequent
Cutaneous photosensitivity	An increased sensitivity of the skin to light. Photosensitivity may result in a rash upon exposure to the sun (which is known as photodermatosis). Photosensitivity can be diagnosed by phototests in which light is shone on small areas of skin.   Synonyms:Photosensitive skin; Photosensitive skin rashes; Photosensitivity; Sensitivity to sunlight; Skin photosensitivity; Sun sensitivity	Very frequent
Emotional lability	Unstable emotional experiences and frequent mood changes; emotions that are easily aroused, intense, and/or disproportionate to events and circumstances.   Synonyms:Emotional instability; Mood alterations; Mood changes; Mood lability; Mood swings	Very frequent
Hallucinations	Perceptions in a conscious and awake state that, in the absence of external stimuli, have qualities of real perception. These perceptions are vivid, substantial, and located in external objective space.   Synonyms:Hallucination; Hallucinations; Sensory hallucination	Very frequent
Hyperreflexia	Hyperreflexia is the presence of hyperactive stretch reflexes of the muscles.   Synonyms:Increased deep tendon reflexes; Increased reflexes	Very frequent
Hypotonia	Hypotonia is an abnormally low muscle tone (the amount of tension or resistance to movement in a muscle). Even when relaxed, muscles have a continuous and passive partial contraction which provides some resistance to passive stretching. Hypotonia thus manifests as diminished resistance to passive stretching. Hypotonia is not the same as muscle weakness, although the two conditions can co-exist.   Synonyms:Low muscle tone; Low or weak muscle tone; Muscle hypotonia; Muscular hypotonia	Very frequent
Migraine	Migraine is a chronic neurological disorder characterized by episodic attacks of headache and associated symptoms.   Synonyms:Intermittent migraine headaches; Migraine; Migraine headache; Migraine headaches	Very frequent
