Hereditary spastic paraplegia 42(SPG42)

MedGen UID:
393407
•Concept ID:
C2675528
•
Disease or Syndrome
Synonyms: Spastic Paraplegia 42; Spastic paraplegia 42, autosomal dominant
SNOMED CT: Autosomal dominant spastic paraplegia type 42 (763070001)
Modes of inheritance:
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.
Autosomal dominant inheritance (Orphanet)
 
Gene (location): SLC33A1 (3q25.31)
 
Monarch Initiative: MONDO:0012928
OMIM®: 612539
Orphanet: ORPHA171863

Definition

A pure form of hereditary spastic paraplegia with characteristics of slowly progressive spastic paraplegia of lower extremities with an age of onset ranging from childhood to adulthood and patients presenting with spastic gait, increased tendon reflexes in lower limbs, extensor plantar response, weakness and atrophy of lower limb muscles and, in rare cases, pes cavus. No abnormalities are noted on magnetic resonance imaging. [from SNOMEDCT_US]

Clinical features

From HPO
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).

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.
See: Feature record | Search on this feature
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.
