Total 25 clinical symptoms reported for Citrullinemia type I  Uncommon (14)Occasional (10)Frequent (1)

Ankle clonus	Clonus is an involuntary tendon reflex that causes repeated flexion and extension of the foot. Ankle clonus is tested by rapidly flexing the foot upward.   Synonyms:Abnormal rhythmic movements of ankle	Uncommon
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	Uncommon
Coma	Complete absence of wakefulness and content of conscience, which manifests itself as a lack of response to any kind of external stimuli.   Synonyms:Coma	Uncommon
Gastroesophageal reflux	A condition in which the stomach contents leak backwards from the stomach into the esophagus through the lower esophageal sphincter.   Synonyms:Acid reflux; Acid reflux disease; Gastro-esophageal reflux; Gastroesophageal reflux disease; GERD; Heartburn	Uncommon
Headache	Cephalgia, or pain sensed in various parts of the head, not confined to the area of distribution of any nerve.   Synonyms:Headache; Headaches	Uncommon
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	Uncommon
Increased intracranial pressure	An increase of the pressure inside the cranium (skull) and thereby in the brain tissue and cerebrospinal fluid.   Synonyms:Intracranial hypertension; Intracranial pressure elevation; Rise in pressure inside skull	Uncommon
Intellectual disability, mild	Mild intellectual disability is defined as an intelligence quotient (IQ) in the range of 50-69.   Synonyms:Intellectual disability, mild; Mental retardation, borderline-mild; Mild and nonprogressive mental retardation; Mild mental retardation	Uncommon
Loss of consciousness	Synonyms:Loss of consciousness; Passing out	Uncommon
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	Uncommon
Scotoma	A regional and pathological increase of the light detection threshold in any region of the visual field surrounded by a field of normal or relatively well-preserved vision.	Uncommon
Slurred speech	Abnormal coordination of muscles involved in speech.   Synonyms:Slurred speech	Uncommon
Tachypnea	Very rapid breathing.   Synonyms:Increased respiratory rate or depth of breathing; Polypnea	Uncommon
Torticollis	Involuntary contractions of the neck musculature resulting in an abnormal posture of or abnormal movements of the head.   Synonyms:Cervical dystonia; Loxia; Spasmodic torticollis; Wry neck	Uncommon
