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).
Dysarthria- MedGen UID:
- 8510
- •Concept ID:
- C0013362
- •
- Mental or Behavioral Dysfunction
Dysarthric speech is a general description referring to a neurological speech disorder characterized by poor articulation. Depending on the involved neurological structures, dysarthria may be further classified as spastic, flaccid, ataxic, hyperkinetic and hypokinetic, or mixed.

An unintentional, oscillating to-and-fro muscle movement about a joint axis.
Photophobia- MedGen UID:
- 43220
- •Concept ID:
- C0085636
- •
- Sign or Symptom
Excessive sensitivity to light with the sensation of discomfort or pain in the eyes due to exposure to bright light.
Leukoencephalopathy- MedGen UID:
- 78722
- •Concept ID:
- C0270612

- Disease or Syndrome
Reduced strength of one or more muscles innervated by the facial nerve (the seventh cranial nerve).
Generalized amyotrophy- MedGen UID:
- 234650
- •Concept ID:
- C1389113
- •
- Disease or Syndrome
Generalized (diffuse, unlocalized) amyotrophy (muscle atrophy) affecting multiple muscles.
Increased variability in muscle fiber diameter- MedGen UID:
- 336019
- •Concept ID:
- C1843700
- •
- Finding
An abnormally high degree of muscle fiber size variation. This phenotypic feature can be observed upon muscle biopsy.
Distal amyotrophy- MedGen UID:
- 338530
- •Concept ID:
- C1848736
- •
- Disease or Syndrome
Muscular atrophy affecting muscles in the distal portions of the extremities.
Rimmed vacuoles- MedGen UID:
- 340089
- •Concept ID:
- C1853932
- •
- Finding
Presence of abnormal vacuoles (membrane-bound organelles) in the sarcolemma. On histological staining with hematoxylin and eosin, rimmed vacuoles are popcorn-like clear vacuoles with a densely blue rim. The vacuoles are often associated with cytoplasmic and occasionally intranuclear eosinophilic inclusions.
Increased endomysial connective tissue- MedGen UID:
- 867771
- •Concept ID:
- C4022161
- •
- Finding
An increased volume of the endomysium, which is a connective tissue sheath that surrounds each muscule fiber. Together, bundles of muscle fibers form a fasciculus, surrounded by another layer of connective tissue called the perimysium.
Internally nucleated skeletal muscle fibers- MedGen UID:
- 1623054
- •Concept ID:
- C4531255
- •
- Anatomical Abnormality
An abnormally increased proportion of nuclei of sarcomeres with an internal localization. Individual muscle fibers are syncytia, formed by embryonic fusion of many myoblasts or later, myosatellite cells. Each muscle fiber contains many nuclei, peripherally positioned immediately adjacent to the sarcolemmal membrane. In healthy muscle only 3-5% of fibers contain nuclei that are located internally, within the cell, but many disease processes lead to internal nuclei.
Elevated circulating creatine kinase concentration- MedGen UID:
- 69128
- •Concept ID:
- C0241005
- •
- Finding
An elevation of the level of the enzyme creatine kinase (also known as creatine phosphokinase (CK; EC 2.7.3.2) in the blood. CK levels can be elevated in a number of clinical disorders such as myocardial infarction, rhabdomyolysis, and muscular dystrophy.
Ptosis- MedGen UID:
- 2287
- •Concept ID:
- C0005745
- •
- Disease or Syndrome
The upper eyelid margin is positioned 3 mm or more lower than usual and covers the superior portion of the iris (objective); or, the upper lid margin obscures at least part of the pupil (subjective).
Miosis- MedGen UID:
- 6409
- •Concept ID:
- C0026205
- •
- Disease or Syndrome
Abnormal (non-physiological) constriction of the pupil.
Ophthalmoplegia- MedGen UID:
- 45205
- •Concept ID:
- C0029089
- •
- Sign or Symptom
Paralysis of one or more extraocular muscles that are responsible for eye movements.
Pigmentary retinopathy- MedGen UID:
- 1643295
- •Concept ID:
- C4551715
- •
- Disease or Syndrome
An abnormality of the retina characterized by pigment deposition. It is typically associated with migration and proliferation of macrophages or retinal pigment epithelial cells into the retina; melanin from these cells causes the pigmentary changes. Pigmentary retinopathy is a common final pathway of many retinal conditions and is often associated with visual loss.
