Expanded phenotype in a patient with spastic paraplegia 7.

Area of Science:

• Neurogenetics
• Clinical Neurology

Background:

• Hereditary spastic paraplegia (HSP) comprises a group of genetically diverse neurodegenerative disorders.
• HSP is typically characterized by progressive weakness and spasticity in the lower limbs.

Observation:

• This study reports on a patient diagnosed with spastic paraplegia type 7 (SPG7).
• The patient presented with an expanded phenotype beyond the typical clinical manifestations of SPG7.

Findings:

• Pathogenic variants in the SPG7 gene were identified as the cause of the patient's condition.
• The discovery of these variants in SPG7 led to the diagnosis of SPG7.

Implications:

• This case expands the known phenotypic spectrum associated with SPG7 mutations.
• Understanding expanded phenotypes is crucial for accurate diagnosis and genetic counseling in hereditary spastic paraplegia.
