Short stature- MedGen UID:
- 87607
- •Concept ID:
- C0349588
- •
- Finding
A height below that which is expected according to age and gender norms. Although there is no universally accepted definition of short stature, many refer to "short stature" as height more than 2 standard deviations below the mean for age and gender (or below the 3rd percentile for age and gender dependent norms).
Failure to thrive in infancy- MedGen UID:
- 358083
- •Concept ID:
- C1867873
- •
- Finding
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).
Dystonic disorder- MedGen UID:
- 3940
- •Concept ID:
- C0013421
- •
- Sign or Symptom
An abnormally increased muscular tone that causes fixed abnormal postures. There is a slow, intermittent twisting motion that leads to exaggerated turning and posture of the extremities and trunk.
Spastic diplegia- MedGen UID:
- 44181
- •Concept ID:
- C0023882
- •
- Disease or Syndrome
Spasticity (neuromuscular hypertonia) primarily in the muscles of the legs, hips, and pelvis.
Myoclonus- MedGen UID:
- 10234
- •Concept ID:
- C0027066
- •
- Finding
Very brief, involuntary random muscular contractions occurring at rest, in response to sensory stimuli, or accompanying voluntary movements.
Babinski sign- MedGen UID:
- 19708
- •Concept ID:
- C0034935
- •
- Finding
Upturning of the big toe (and sometimes fanning of the other toes) in response to stimulation of the sole of the foot. If the Babinski sign is present it can indicate damage to the corticospinal tract.
Delayed speech and language development- MedGen UID:
- 105318
- •Concept ID:
- C0454644
- •
- Finding
A degree of language development that is significantly below the norm for a child of a specified age.
Bilateral tonic-clonic seizure- MedGen UID:
- 141670
- •Concept ID:
- C0494475
- •
- Sign or Symptom
A bilateral tonic-clonic seizure is a seizure defined by a tonic (bilateral increased tone, lasting seconds to minutes) and then a clonic (bilateral sustained rhythmic jerking) phase.
Increased CSF lactate- MedGen UID:
- 257904
- •Concept ID:
- C1167918
- •
- Finding
Increased concentration of lactate in the cerebrospinal fluid.
Motor delay- MedGen UID:
- 381392
- •Concept ID:
- C1854301
- •
- Finding
A type of Developmental delay characterized by a delay in acquiring motor skills.
Brisk reflexes- MedGen UID:
- 382164
- •Concept ID:
- C2673700
- •
- Finding
Tendon reflexes that are noticeably more active than usual (conventionally denoted 3+ on clinical examination). Brisk reflexes may or may not indicate a neurological lesion. They are distinguished from hyperreflexia by the fact that hyerreflexia is characterized by hyperactive repeating (clonic) reflexes, which are considered to be always abnormal.
Increased CSF alanine concentration- MedGen UID:
- 1690583
- •Concept ID:
- C5139618
- •
- Finding
Abnormally increased levels of alanine in cerebrospinal fluid.
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.
Cytochrome C oxidase-negative muscle fibers- MedGen UID:
- 867360
- •Concept ID:
- C4021724
- •
- Finding
An abnormally reduced activity of the enzyme cytochrome C oxidase in muscle tissue.
Lactic acidosis- MedGen UID:
- 1717
- •Concept ID:
- C0001125
- •
- Disease or Syndrome
An abnormal buildup of lactic acid in the body, leading to acidification of the blood and other bodily fluids.
Increased intramyocellular lipid droplets- MedGen UID:
- 866481
- •Concept ID:
- C4020730
- •
- Finding
An abnormal increase in intracellular lipid droplets In a muscle. The number and size of these drops can increase with somd disorders of lipid metabolism affecting muscle. See PMID 20691590 for histological images.
Decreased activity of mitochondrial complex IV- MedGen UID:
- 866520
- •Concept ID:
- C4020800
- •
- Finding
A reduction in the activity of the mitochondrial respiratory chain complex IV, which is part of the electron transport chain in mitochondria.
- Abnormal cellular phenotype
- Abnormality of metabolism/homeostasis
- Abnormality of the musculoskeletal system
- Abnormality of the nervous system
- Growth abnormality
