Spastic ataxia 4(SPAX4)

MedGen UID:
462275
Concept ID:
C3150925
Disease or Syndrome
Synonym: Ataxia, spastic, 4, autosomal recessive
SNOMED CT: Autosomal recessive spastic ataxia type 4 (784347002); Autosomal recessive spastic ataxia, optic atrophy, dysarthria syndrome (784347002); SPAX 4 - autosomal recessive spastic ataxia type 4 (784347002)
Modes of inheritance:
Autosomal recessive inheritance
MedGen UID:
141025
Concept ID:
C0441748
Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele).
 
Gene (location): MTPAP (10p11.23)
 
Monarch Initiative: MONDO:0013354
OMIM®: 613672
Orphanet: ORPHA254343

Definition

A rare genetic autosomal recessive spastic ataxia disease with characteristics of the onset in early childhood of spastic paraparesis, cerebellar ataxia, dysarthria and optic atrophy. Caused by homozygous mutation in the MTPAP gene on chromosome 10p11. [from SNOMEDCT_US]

Clinical features

From HPO
Decreased Achilles reflex
MedGen UID:
324765
Concept ID:
C1837323
Finding
Decreased intensity of the Achilles reflex (also known as the ankle jerk reflex), which can be elicited by tapping the tendon is tapped while the foot is dorsiflexed.
Lower limb hypertonia
MedGen UID:
375612
Concept ID:
C1845245
Finding
Upper limb hypertonia
MedGen UID:
867515
Concept ID:
C4021898
Anatomical Abnormality
Increased muscle tone observed in the arms of the affected person.
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.
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.
Spastic paraparesis
MedGen UID:
52432
Concept ID:
C0037771
Sign or Symptom
Mild or moderate loss of motor function accompanied by spasticity in the lower extremities. This condition is a manifestation of CENTRAL NERVOUS SYSTEM DISEASES that cause injury to the motor cortex or descending motor pathways.
Emotional lability
MedGen UID:
39319
Concept ID:
C0085633
Mental or Behavioral Dysfunction
Unstable emotional experiences and frequent mood changes; emotions that are easily aroused, intense, and/or disproportionate to events and circumstances.
Hyperactive patellar reflex
MedGen UID:
66003
Concept ID:
C0240116
Finding
Delayed ability to walk
MedGen UID:
66034
Concept ID:
C0241726
Finding
A failure to achieve the ability to walk at an appropriate developmental stage. Most children learn to walk in a series of stages, and learn to walk short distances independently between 12 and 15 months.
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.
Limb ataxia
MedGen UID:
196692
Concept ID:
C0750937
Finding
A kind of ataxia that affects movements of the extremities.
Gait ataxia
MedGen UID:
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.
Spastic ataxia
MedGen UID:
376528
Concept ID:
C1849156
Disease or Syndrome
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.
