Description
Hereditary spastic paraplegia-72A (SPG72A) is a rare genetic disorder characterized by early childhood onset of slowly progressive crural spastic paraparesis, presenting with:
- Spastic gait
- Mild stiffness at rest
- Hyperreflexia in the lower limbs
- Extensor plantar responses
- In some cases, mild postural tremor, pes cavus (high arches), sphincter disturbances, and sensory loss at ankles
The disorder is slowly progressive, and some patients develop the need for assistance in walking. The symptoms typically start in early childhood and worsen over time.

Signs and Symptoms
Hereditary Spastic Paraplegia (HSP) 72A, also known as SPG72A, is a rare genetic disorder that affects the nervous system. The signs and symptoms of HSP 72A can vary from person to person, but they often include:
- Difficulty walking: People with HSP 72A may experience difficulty walking or maintaining balance due to weakness and stiffness in their legs [3].
- Stiffness and spasticity: Muscle stiffness and spasms are common symptoms of HSP 72A, which can affect the legs and other parts of the body [1][6][9].
- Weakness: Weakness in the legs and other muscles is a hallmark symptom of HSP 72A, which can progress over time [2][7][8].
- Hyperreflexia: Some people with HSP 72A may experience hyperreflexia, or an increased reflex response to stimuli [9].
It's essential to note that the symptoms of HSP 72A can vary in severity and progression from person to person. In some cases, the condition may be mild, while in others it can be more severe.

Diagnostic Tests
Hereditary spastic paraplegia (HSP) 72A, also known as SPG72A, is a rare autosomal dominant pure form of hereditary spastic paraplegia. Diagnostic tests for this condition are crucial in confirming the diagnosis and developing an effective treatment plan.
Genetic Testing Genetic testing is a key diagnostic tool for HSP 72A. It involves analyzing a patient's DNA to identify specific gene mutations associated with the condition [5]. This can be done through various techniques, such as PCR (Polymerase Chain Reaction) or sequencing [10].
Neuroimaging Tests Neuroimaging tests, including MRI and CT scans, may also aid in diagnosing HSP 72A. These tests allow doctors to visualize the brain and spinal cord, looking for any structural abnormalities or signs of damage [11]. However, these tests are not specific to HSP 72A and can be used to rule out other conditions.
Clinical Evaluation A comprehensive clinical evaluation is also essential in diagnosing HSP 72A. This includes a physical exam, neurological exam, and testing to assess the patient's symptoms, medical history, and family medical history [15]. The diagnosis may be aided by neuroimaging and genetic testing [6].
Diagnostic Tests Mentioned The following diagnostic tests are mentioned in the context:
- Genetic testing: Analyzing a patient's DNA to identify specific gene mutations associated with HSP 72A [5].
- Neuroimaging tests (MRI and CT scans): Visualizing the brain and spinal cord to rule out other conditions or detect structural abnormalities [11].
- Clinical evaluation: Assessing symptoms, medical history, and family medical history through physical and neurological exams [15].
Please note that these diagnostic tests are not exhaustive, and a healthcare provider may recommend additional tests based on individual patient needs.
Treatment
Hereditary Spastic Paraplegia 72A (SPG72A) is a complex neurological disorder that primarily affects the lower limbs, causing progressive weakness and stiffness. While there is no cure for SPG72A, various treatments can help manage its symptoms.
Symptomatic Treatment
The primary goal of treatment for SPG72A is to alleviate symptoms such as spasticity, muscle stiffness, and difficulty walking. Some medications used to treat SPG72A include:
- Baclofen: A muscle relaxant that can help reduce muscle spasms and stiffness [5].
- Tizanidine: An alpha-2 adrenergic agonist that can help relieve muscle spasticity [9].
- Diazepam: A benzodiazepine that can be used to treat muscle spasms and anxiety associated with SPG72A [10].
Intrathecal Baclofen Therapy
In some cases, intrathecal baclofen therapy may be recommended for patients with severe spasticity. This involves delivering a precise dose of baclofen directly into the spinal fluid to reduce muscle stiffness and spasms [8].
Novel Disease-Modifying Agents
Researchers are exploring novel disease-modifying agents, including small molecules and gene therapies, that can potentially slow or halt disease progression in childhood-onset complex HSP, which may also be relevant for SPG72A [5].
It's essential to note that treatment plans should be tailored to individual patients and may involve a multidisciplinary approach. Consultation with a qualified specialist is crucial for developing an effective treatment strategy.

Differential Diagnosis
Hereditary spastic paraplegia (HSP) is a group of clinically and genetically diverse disorders that share a primary feature, which is the causation of progressive and generally severe lower extremity weakness and spasticity. Hereditary spastic paraplegia-72A (SPG72A) is a pure form of spastic paraplegia with onset of difficulty walking and stiff legs associated with hyperreflexia [3][7].
The differential diagnosis for SPG72A includes structural abnormalities involving the brain or spinal cord, such as tethered cord syndrome and spinal cord compression [2]. It's essential to consider these conditions when diagnosing SPG72A.
Other conditions that may be considered in the differential diagnosis of HSP include:
- Structural abnormalities involving the brain or spinal cord (e.g., tethered cord syndrome and spinal cord compression)
- Complicated hereditary spastic paraplegia, which includes a wide range of symptoms that impact the brain, spinal cord, and nerves (neurological symptoms) [6]
- Cerebellar ataxia and spastic paraplegia phenotype, which can be challenging to diagnose due to its broad differential diagnosis [13]
It's worth noting that the term "differential" is used nonrigorously in calculus to refer to an infinitesimal ("infinitely small") change in some varying quantity. However, in the context of medicine and HSP, it refers to a process of ruling out other possible causes or conditions that may present with similar symptoms [10].
In summary, the differential diagnosis for SPG72A involves considering structural abnormalities involving the brain or spinal cord, complicated hereditary spastic paraplegia, cerebellar ataxia and spastic paraplegia phenotype, and other conditions that may present with similar symptoms.
