The frequent variant A57F in the gene in patients from Russia has Finno-Ugric Mari origin.

Introduction: GNE-myopathy is a distal myopathy with adult-onset and initial involvement of anterior leg compartment. A founder effect has been demonstrated for some patients from several large cohorts in different countries.

Methods: In this study, we investigated the allele frequency of the c.

Common Variants in the Gene with Unclear Pathogenicity as the Cause of Oculocutaneous Albinism in a Cohort of Russian Patients.

oculocutaneous albinism (OCA) is a hereditary impairment of skin, hair, and eye pigmentation. The most common form of albinism is autosomal recessive albinism, caused by mutations in the gene, accounting for approximately 40-50% of all cases of the disease in European populations. Common hypomorphic variants in the gene could lead to a mild form of albinism in a compound heterozygous state with a pathogenic variant.

Clinical and Molecular Findings in Patients with Knobloch Syndrome 1: Case Series Report.

Background/objectives: Knobloch syndrome 1 (KS) is an autosomal recessive inherited ocular syndrome characterized by a combination of high myopia, vitreoretinal degeneration, and occipital encephalocele. KS is caused by biallelic pathogenic variants in the gene. Diagnosing KS can be challenging due to its clinical heterogeneity and the rarity of the syndrome.

The Study of the Inheritance Mechanisms of Myotonic Dystrophy Type 1 (DM1) in Families from the Republic of North Ossetia-Alania.

Myotonic dystrophy type 1 (DM1) is a multisystem disorder with progressive myopathy and myotonia. The clinical study was conducted in the Republic of North Ossetia-Alania (RNOA), and in it 39 individuals from 17 unrelated families were identified with DM1. Clinical presentations varied, including muscle weakness, fatigue, intellectual disability, hypersomnia, ophthalmological abnormalities, and alopecia.

Rare IFT140-Associated Phenotype of Cranioectodermal Dysplasia and Features of Diagnostic Journey in Patients with Suspected Ciliopathies.

Here we present a patient with a cranioectodermal phenotype associated with pathogenic variants in the gene. Most frequently, pathogenic variants in correspond to the phenotype of Mainzer-Saldino syndrome. Only four patients have previously been described with this cranioectodermal phenotype and variants in .

High carrier frequency of a nonsense p.Trp230* variant in gene in Ossetians.

Background: Congenital adrenal hyperplasia (CAH) caused by 3β-HSD deficiency is a rare form of congenital adrenal deficiency with an autosomal recessive type of inheritance. Previously we have demonstrated that a single nucleotide variant (SNV) p.Trp230* in the homozygous state is a frequent cause of CAH among the indigenous population of North Ossetia-Alania represented by Ossetians.

[The effectiveness of spasmolytic therapy in chronic acalculous cholecystitis].

The therapeutic efficacy of duspatalin was evaluated in 69 patients with chronic cholecystitis and dyskinesia of the biliary tract (BT). Supplementation of duspatalin to the combined therapy in the patients with chronic cholecystitis shown to exert a pronounced therapeutic effect. This caused positive changes in clinical symptoms and BT function and quality of life, diminished the lithogenic properties of bile.

Measurement of the toughness of bone: a tutorial with special reference to small animal studies.

Quantitative assessment of the strength and toughness of bone has become an integral part of many biological and bioengineering studies on the structural properties of bone and their degradation due to aging, disease and therapeutic treatment. Whereas the biomechanical techniques for characterizing bone strength are well documented, few studies have focused on the theory, methodology, and various experimental procedures for evaluating the fracture toughness of bone, i.e.

[Features of microcirculatory disorders in acute and recurrent hemorrhagic vasculitis (Schönlein-Henoch disease)].

Aim: To study microcirculatory disturbances in acute and chronic hemorrhagic vasculitis (HV).

Material And Methods: The examination of 44 HV patients included clinical and immunological examinations, conjunctival biomicroscopy, tests for blood viscosity, aggregation of erythrocytes, coagulation parameters. In 8 patients morphological examination of skin microvessels was made (light microscopy and electron microscopy).
