- •Concept ID:
- C0728829
- •
- Congenital Abnormality
An increase in height of the medial longitudinal arch of the foot that does not flatten on weight bearing (i.e., a distinctly hollow form of the sole of the foot when it is bearing weight).

Hyperextension of the metatarsal-phalangeal joint with hyperflexion of the proximal interphalangeal (PIP) joint.
Areflexia- MedGen UID:
- 115943
- •Concept ID:
- C0234146
- •
- Finding
Absence of neurologic reflexes such as the knee-jerk reaction.
Action tremor- MedGen UID:
- 65875
- •Concept ID:
- C0234376
- •
- Sign or Symptom
A tremor present when the limbs are active, either when outstretched in a certain position or throughout a voluntary movement.
Hyporeflexia- MedGen UID:
- 195967
- •Concept ID:
- C0700078

- 155642
- •Concept ID:
- C0751837
- •
- Sign or Symptom
A type of ataxia characterized by the impairment of the ability to coordinate the movements required for normal walking. Gait ataxia is characteirzed by a wide-based staggering gait with a tendency to fall.

- 322038
- •Concept ID:
- C1832776
- •
- Finding
Segmental peripheral demyelination/remyelination- MedGen UID:
- 335873
- •Concept ID:
- C1843077
- •
- Finding
A segmental pattern of demyelination and regeneration (remyelination) affecting peripheral nerves.
Distal sensory impairment- MedGen UID:
- 335722
- •Concept ID:
- C1847584
- •
- Finding
An abnormal reduction in sensation in the distal portions of the extremities.
Onion bulb formation- MedGen UID:
- 376237
- •Concept ID:
- C1847906
- •
- Finding
Repeated episodes of segmental demyelination and remyelination lead to the accumulation of supernumerary Schwann cells around axons, which is referred to as onion bulb formation. This finding affects peripheral nerves.

- 388130
- •Concept ID:
- C1858729
- •
- Finding
