Cerebellar ataxia- MedGen UID:
- 849
- •Concept ID:
- C0007758
- •
- Disease or Syndrome
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).
Spasticity- MedGen UID:
- 7753
- •Concept ID:
- C0026838
- •
- Sign or Symptom
A motor disorder characterized by a velocity-dependent increase in tonic stretch reflexes with increased muscle tone, exaggerated (hyperexcitable) tendon reflexes.
Seizure- MedGen UID:
- 20693
- •Concept ID:
- C0036572
- •
- Sign or Symptom
A seizure is an intermittent abnormality of nervous system physiology characterized by a transient occurrence of signs and/or symptoms due to abnormal excessive or synchronous neuronal activity in the brain.
Global developmental delay- MedGen UID:
- 107838
- •Concept ID:
- C0557874
- •
- Finding
A delay in the achievement of motor or mental milestones in the domains of development of a child, including motor skills, speech and language, cognitive skills, and social and emotional skills. This term should only be used to describe children younger than five years of age.
Intellectual disability- MedGen UID:
- 811461
- •Concept ID:
- C3714756
- •
- Mental or Behavioral Dysfunction
Intellectual disability, previously referred to as mental retardation, is characterized by subnormal intellectual functioning that occurs during the developmental period. It is defined by an IQ score below 70.
Hypotonia- MedGen UID:
- 10133
- •Concept ID:
- C0026827
- •
- Finding
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.
Generalized hypotonia- MedGen UID:
- 346841
- •Concept ID:
- C1858120
- •
- Finding
Generalized muscular hypotonia (abnormally low muscle tone).
Hypopigmentation of the skin- MedGen UID:
- 102477
- •Concept ID:
- C0162835
- •
- Disease or Syndrome
A reduction of skin color related to a decrease in melanin production and deposition.
Silver-gray hair- MedGen UID:
- 322949
- •Concept ID:
- C1836576
- •
- Finding
Hypopigmented hair that appears silver-gray.
Accumulation of melanosomes in melanocytes- MedGen UID:
- 375180
- •Concept ID:
- C1843389
- •
- Finding
Melanin pigment aggregation in hair shafts- MedGen UID:
- 375181
- •Concept ID:
- C1843390
- •
- Finding
Exotropia- MedGen UID:
- 4613
- •Concept ID:
- C0015310
- •
- Disease or Syndrome
A form of strabismus with one or both eyes deviated outward.
Nystagmus- MedGen UID:
- 45166
- •Concept ID:
- C0028738
- •
- Disease or Syndrome
Rhythmic, involuntary oscillations of one or both eyes related to abnormality in fixation, conjugate gaze, or vestibular mechanisms.
- Abnormality of the eye
- Abnormality of the integument
- Abnormality of the musculoskeletal system
- Abnormality of the nervous system
