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.
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.
Hypsarrhythmia- MedGen UID:
- 195766
- •Concept ID:
- C0684276
- •
- Finding
Hypsarrhythmia is abnormal interictal high amplitude waves and a background of irregular spikes. There is continuous (during wakefulness), high-amplitude (>200 Hz), generalized polymorphic slowing with no organized background and multifocal spikes demonstrated by electroencephalography (EEG).
Bilateral tonic-clonic seizure with focal onset- MedGen UID:
- 164077
- •Concept ID:
- C0877017
- •
- Disease or Syndrome
A bilateral tonic-clonic seizure with focal onset is a focal-onset seizure which progresses into a bilateral tonic-clonic phase.
Myoclonic seizure- MedGen UID:
- 1385980
- •Concept ID:
- C4317123
- •
- Sign or Symptom
A myoclonic seizure is a type of motor seizure characterized by sudden, brief (<100 ms) involuntary single or multiple contraction of muscles or muscle groups of variable topography (axial, proximal limb, distal). Myoclonus is less regularly repetitive and less sustained than is clonus.
Flexion contracture- MedGen UID:
- 83069
- •Concept ID:
- C0333068
- •
- Anatomical Abnormality
A flexion contracture is a bent (flexed) joint that cannot be straightened actively or passively. It is thus a chronic loss of joint motion due to structural changes in muscle, tendons, ligaments, or skin that prevents normal movement of joints.
Prominent metopic ridge- MedGen UID:
- 387953
- •Concept ID:
- C1857949
- •
- Finding
Vertical bony ridge positioned in the midline of the forehead.
Diabetes mellitus type 1- MedGen UID:
- 41522
- •Concept ID:
- C0011854
- •
- Disease or Syndrome
Type 1 diabetes mellitus (T1D), also designated insulin-dependent diabetes mellitus (IDDM), is a disorder of glucose homeostasis characterized by susceptibility to ketoacidosis in the absence of insulin therapy. It is a genetically heterogeneous autoimmune disease affecting about 0.3% of Caucasian populations (Todd, 1990). Genetic studies of T1D have focused on the identification of loci associated with increased susceptibility to this multifactorial phenotype.
The classic phenotype of diabetes mellitus is polydipsia, polyphagia, and polyuria which result from hyperglycemia-induced osmotic diuresis and secondary thirst. These derangements result in long-term complications that affect the eyes, kidneys, nerves, and blood vessels.
Hyperglycemia- MedGen UID:
- 5689
- •Concept ID:
- C0020456
- •
- Disease or Syndrome
An increased concentration of glucose in the blood.
Ketoacidosis- MedGen UID:
- 67434
- •Concept ID:
- C0220982
- •
- Disease or Syndrome
Acidosis resulting from accumulation of ketone bodies.
Reduced C-peptide level- MedGen UID:
- 909412
- •Concept ID:
- C4280764
- •
- Finding
A decreased concentration of C-peptide in the circulation. Since C-peptide is secreted in equimolar amounts to insulin, this feature correlates with reduced insulin secretion.
Downturned corners of mouth- MedGen UID:
- 356471
- •Concept ID:
- C1866195
- •
- Anatomical Abnormality
A morphological abnormality of the mouth in which the angle of the mouth is downturned. The oral commissures are positioned inferior to the midline labial fissure.
Bilateral ptosis- MedGen UID:
- 356120
- •Concept ID:
- C1865916
- •
- Disease or Syndrome
- Abnormality of head or neck
- Abnormality of metabolism/homeostasis
- Abnormality of the eye
- Abnormality of the musculoskeletal system
- Abnormality of the nervous system
