Summary
The first Russian clinical cases of hereditary motor and sensory neuropathy type 4A (HMSN 4A) are presented. Molecular-genetic testing confirmed diagnoses in patients aged 5-34, aiding in identifying GDAP1 gene mutations.
Area of Science:
- Neurology
- Genetics
- Clinical Medicine
Context:
- Presents the initial documented clinical cases of autosomal-recessive hereditary motor and sensory neuropathy type 4A (HMSN 4A) within the Russian Federation.
- Highlights the diagnostic challenges and genetic underpinnings of this rare neurological disorder.
Purpose:
- To report the first clinical cases of HMSN 4A in Russia.
- To detail the clinical manifestations and disease progression in affected individuals.
- To establish criteria for selecting patients for GDAP1 gene mutation analysis.
Summary:
- Describes clinical and molecular-genetic findings in Russian patients with HMSN 4A, ranging from 5 to 34 years old.
- Analysis covers disease duration (3-29 years) and specific clinical features.
- Molecular-genetic methods, specifically DNA diagnostics, verified the diagnosis in all presented cases.
Impact:
- Establishes a baseline for HMSN 4A diagnosis and research in Russia.
- Provides crucial data for understanding the clinical spectrum of HMSN 4A.
- Facilitates targeted genetic testing for GDAP1 mutations in suspected cases.

01:22Diabetic Neuropathy
DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...
01:21Huntington Disease l: Introduction
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
01:12Alterations in Muscle Tone ll
Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...
01:19Multiple Sclerosis l: Introduction
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
01:22Myasthenia Gravis ll: Pathophysiology
The disease process of myasthenia gravis begins at the neuromuscular junction, where antibodies attack key proteins needed for muscle activation. This immune reaction weakens signal transmission, leading to the characteristic muscle fatigue and weakness that define the condition.Immune-Mediated DamageIn most individuals, antibodies target acetylcholine receptors (AChRs) on the postsynaptic membrane of muscle cells. By blocking acetylcholine binding, these antibodies prevent the nerve signal...
01:11Alterations in Muscle Tone lll
Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...
