Clubfoot- MedGen UID:

- •
- Congenital Abnormality
Clubfoot is a congenital limb deformity defined as fixation of the foot in cavus, adductus, varus, and equinus (i.e., inclined inwards, axially rotated outwards, and pointing downwards) with concomitant soft tissue abnormalities (Cardy et al., 2007). Clubfoot may occur in isolation or as part of a syndrome (e.g., diastrophic dysplasia, 222600). Clubfoot has been reported with deficiency of long bones and mirror-image polydactyly (Gurnett et al., 2008; Klopocki et al., 2012).

- C1866141
- •
- Finding
Weakness of the muscles responsible for dorsiflexion of the foot, that is, of the movement of the toes towards the shin. The foot dorsiflexors include the tibialis anterior, the extensor hallucis longus, the extensor digitorum longus, and the peroneus tertius muscles.

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.

Cognitive impairment- MedGen UID:
- 90932
- •Concept ID:

Hypoplasia of the corpus callosum- MedGen UID:
- 138005

- •
- Congenital Abnormality
Underdevelopment of the corpus callosum.
Steppage gait- MedGen UID:
- 98105
- •Concept ID:
- C0427149
- •
- Finding
An abnormal gait pattern that arises from weakness of the pretibial and peroneal muscles due to a lower motor neuron lesion. Affected patients have footdrop and are unable to dorsiflex and evert the foot. The leg is lifted high on walking so that the toes clear the ground, and there may be a slapping noise when the foot strikes the ground again.
Knee clonus- MedGen UID:
- 488908
- •Concept ID:
- C0520823
- •
- Finding
Clonus is an involuntary tendon reflex that causes repeated flexion and extension of the foot. Knee clonus can be tested by rapidly pushing the patella towards the toes.
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.
Gait disturbance- MedGen UID:
- 107895
- •Concept ID:
- C0575081
- •
- Finding
The term gait disturbance can refer to any disruption of the ability to walk.
Peripheral axonal neuropathy- MedGen UID:
- 266071
- •Concept ID:
- C1263857
- •
- Disease or Syndrome
An abnormality characterized by disruption of the normal functioning of peripheral axons.
Lower limb spasticity- MedGen UID:
- 220865
- •Concept ID:
- C1271100
- •
- Finding
Spasticity (velocity-dependent increase in tonic stretch reflexes with increased muscle tone and hyperexcitable tendon reflexes) in the muscles of the lower limbs, hips, and pelvis.
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.
Impaired distal vibration sensation- MedGen UID:
- 381262
- •Concept ID:
- C1853767
- •
- Finding
A decrease in the ability to perceive vibration in the distal portions of the limbs.
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.
Impaired distal tactile sensation- MedGen UID:
- 867225
- •Concept ID:
- C4021583
- •
- Finding
A reduced sense of touch (tactile sensation) on the skin of the distal limbs. This is usually tested with a wisp of cotton or a fine camel's hair brush, by asking patients to say 'now' each time they feel the stimulus.
Tibialis anterior muscle atrophy- MedGen UID:
- 868961
- •Concept ID:
- C4023375
- •
- Finding
Wasting of the tibialis anterior muscle.
Lower limb amyotrophy- MedGen UID:
- 870475
- •Concept ID:
- C4024921

- Finding
Muscular atrophy affecting the lower limb.
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.
Optic atrophy- MedGen UID:
- 18180
- •Concept ID:
- C0029124
- •
- Disease or Syndrome
Atrophy of the optic nerve. Optic atrophy results from the death of the retinal ganglion cell axons that comprise the optic nerve and manifesting as a pale optic nerve on fundoscopy.
Strabismus- MedGen UID:
- 21337
- •Concept ID:
- C0038379
- •
- Disease or Syndrome
A misalignment of the eyes so that the visual axes deviate from bifoveal fixation. The classification of strabismus may be based on a number of features including the relative position of the eyes, whether the deviation is latent or manifest, intermittent or constant, concomitant or otherwise and according to the age of onset and the relevance of any associated refractive error.
Central scotoma- MedGen UID:
- 57750
- •Concept ID:
- C0152191
- •
- Finding
An area of depressed vision located at the point of fixation and that interferes with central vision.
