Amyotrophic lateral sclerosis (ALS) is a severe neurodegenerative disease within the spectrum of motor neuron disorders, selectively targeting central and peripheral motor neurons in the brain and spinal cord, with highly variable clinical manifestations. One rare form of ALS is progressive muscular atrophy (PMA), primarily characterized by the selective involvement of peripheral motor neurons and a slower, less aggressive progression compared to classical ALS. Currently, the scientific community lacks consensus on whether PMA should be classified as a distinct nosological entity or as a subtype of ALS. Recent advancements in genetic research have identified that familial and hereditary forms of ALS are most frequently linked to mutations in the SOD1, TARDBP, C9orf72, and FUS genes, among others. Moreover, increasing progress in genetic testing now enables the identification of mutant genes responsible for various phenotypes. Understanding the genetic underpinnings of motor neuron diseases is crucial for elucidating their pathogenesis, which may pave the way for the development of novel diagnostic and therapeutic strategies. This article presents a clinical case involving a patient with a PMA phenotype associated with the H49R mutation in the SOD1 gene. A comprehensive account of the patient’s anamnesis, clinical presentation, molecular-genetic findings, as well as results from instrumental investigations, including electromyography and magnetic resonance imaging, is provided. The article discusses the potential nosological autonomy of PMA and its association with the H49R mutation, referencing current data from both Russian and international studies. Additionally, the article highlights the challenges of differential diagnosis, particularly in distinguishing PMA from other neurodegenerative diseases with similar clinical profiles. This case contributes to the expanding knowledge of the heterogeneity of motor neuron diseases and underscores the importance of molecular-genetic testing in predicting disease prognosis and guiding patient management.

We have studied the impact of harmful physical factors of production on the development of occupational sensorineural hearing loss (OSHL) among civil aviation flight personnel and technological transport drivers in the mining industry of Yakutia. It was found that among flight personnel, OSHL is the only diagnosis of an occupational disease, the severity of hearing loss depends on age, length of service, and the level of excessive noise (typical pattern of OSHL). In car drivers, OSHL is combined with other diagnoses caused by exposure to local and/or general vibration, the clinical course is more severe, with a predominance of II and III degrees

Cerebral amyloid angiopathy (CAA) is a disease of the small cerebral vessels and it mostly affects older people. CAA is characterized by progressive deposition of amyloid-beta in small arteries and arteries of medium caliber, as well as in the capillaries. Sporadic amyloid angiopathy is a cause of recurrent cerebral hemorrhage and cognitive impairment in the elderly. The latest scientific researches and a case report of a patient who suffered from cerebral amyloid angiopathy were used in order to prepare this article. The diagnosis and treatment of CAA are considered

The article presents the results of a clinical and genetic study of a Yakut family with hereditary spastic paraplegia (HSP). Patients with clinically diagnosed HSP and healthy family members were studied. The disease is clinically characterized as a progressive spastic paraplegia of the lower extremities concomitant peripheral neuropathy in advanced case. The methods of exome sequencing of the entire genome, molecular modeling of dynamin-2 and experimental reproduction of key elements of the HSP pathogenesis have been applied. Genetic analysis revealed a novel missense c.2155C> T, p.R719W mutation in the highly conserved GTP-effector domain of the dynamin-2 gene (DNM2). In experiments on HeLa cells, it was shown that mutant dynamin-2 affected endocytosis process. In-silico modeling determined that the identified mutation is located in the DNM2 bundle-signaling element and potentially disrupts the assembly and functional properties of the protein. Testing of this mutation in other Yakut families with HSP showed a negative result, which once again confirms the genetic heterogeneity of this pathology
