Hereditary spastic paraplegia 72(SPG72A)

MedGen UID:
816490
Concept ID:
C3810160
Disease or Syndrome
Synonyms: Spastic paraplegia 72, autosomal recessive; SPG72A
SNOMED CT: Autosomal spastic paraplegia type 72 (782727008)
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).
Autosomal dominant inheritance
MedGen UID:
141047
Concept ID:
C0443147
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 heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.

Definition

Hereditary spastic paraplegia-72A (SPG72A) is a pure form of spastic paraplegia with onset of difficulty walking and stiff legs associated with hyperreflexia and extensor plantar responses in early childhood. The disorder is slowly progressive, and some patients develop the need for assistance in walking. Some patients may have pes cavus or sphincter disturbances. Cognition, speech, and ocular function are normal (summary by Esteves et al., 2014). For a discussion of genetic heterogeneity of autosomal dominant spastic paraplegia, see SPG3A (182600). [from OMIM]

Clinical features

From HPO
Urinary bladder sphincter dysfunction
MedGen UID:
334804
Concept ID:
C1843663
Finding
Abnormal function of a sphincter of the urinary bladder.
Pes cavus
MedGen UID:
675590
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).
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).
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.
Spasticity
MedGen UID:
7753
Concept ID:
C0026838
Sign or Symptom
A motor disorder characterized by a velocity-dependent increase in tonic stretch reflexes with increased muscle tone, exaggerated (hyperexcitable) tendon reflexes.
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 paraplegia
MedGen UID:
20882
Concept ID:
C0037772
Disease or Syndrome
Spasticity and weakness of the leg and hip muscles.
Spastic gait
MedGen UID:
115907
Concept ID:
C0231687
Finding
Spasticity is manifested by increased stretch reflex which is intensified with movement velocity. This results in excessive and inappropriate muscle activation which can contribute to muscle hypertonia. Spastic gait is characterized by manifestations such as muscle hypertonia, stiff knee, and circumduction of the leg.
Hoffmann sign
MedGen UID:
78828
Concept ID:
C0277839
Sign or Symptom
A Hoffmann test is performed by flicking the fingernail of the long finger, from dorsal to volar, on each hand while the hand was supported by the examiner's hand. The test was done with the neck in the neutral position and then with the neck maximally forward flexed. Any flexion of the ipsilateral thumb and/or index finger was interpreted as a positive test.
Tip-toe gait
MedGen UID:
98104
Concept ID:
C0427144
Finding
An abnormal gait pattern characterized by the failure of the heel to contact the floor at the onset of stance during gait.
Lower limb hyperreflexia
MedGen UID:
322973
Concept ID:
C1836696
Finding
Impaired vibration sensation in the lower limbs
MedGen UID:
338617
Concept ID:
C1849134
Finding
A decrease in the ability to perceive vibration in the legs.
Muscle stiffness
MedGen UID:
113151
Concept ID:
C0221170
Sign or Symptom
A condition in which muscles cannot be moved quickly without accompanying pain or spasm.
