CLN6-related continuum phenotype caused by aberrant splicing.

Neuronal ceroid lipofuscinoses (NCLs) are genetically heterogeneous neurodegenerative disorders, characterized by progressive cognitive and motor decline, epilepsy, visual impairment, and shortened life-expectancy. CLN6-related NCLs include both late-infantile and adult myoclonic form. We report a 21-year-old patient, with mild developmental delay, who developed occipital seizures at 14 years, and subsequently cognitive decline, cortical myoclonus, and photosensitivity at low and higher frequencies.

Three-Dimensional Cell Cultures as a Feasible and Promising Alternative to Two-Dimensional and Animal Models in Cancer Research.

Cancer represents one of the diseases with the highest mortality rate worldwide. The burden of cancer continues to increase, not only affecting the health-related quality of life of patients but also causing an elevated global financial impact. The complexity and heterogeneity of cancer pose significant challenges in research and clinical practice, contributing to increase the failure rate of clinical trials for antitumoral drugs.

Myoclonus and Dystonia as Recurrent Presenting Features in Patients with the SCA21-Associated p.Pro170Leu Variant.

Background: Spinocerebellar ataxia 21 (SCA21) is a rare neurological disorder caused by heterozygous variants in . A growing, yet still limited number of reports suggested that hyperkinetic movements should be considered a defining component of the disease.

Case Series: We describe two newly identified families harboring the recurrent pathogenic p.

CIAO1 and MMS19 deficiency: A lethal neurodegenerative phenotype caused by cytosolic Fe-S cluster protein assembly disorders.

Purpose: The functionality of many cellular proteins depends on cofactors; yet, they have only been implicated in a minority of Mendelian diseases. Here, we describe the first 2 inherited disorders of the cytosolic iron-sulfur protein assembly system.

Methods: Genetic testing via genome sequencing was applied to identify the underlying disease cause in 3 patients with microcephaly, congenital brain malformations, progressive developmental and neurologic impairments, recurrent infections, and a fatal outcome.

Dominant VPS16 Pathogenic Variants: Not Only Isolated Dystonia.

Background: VPS16 pathogenic variants have been recently associated with inherited dystonia. Most patients affected by dominant VPS16-related disease display early-onset isolated dystonia with prominent oromandibular, bulbar, cervical, and upper limb involvement, followed by slowly progressive generalization.

Cases: We describe six newly reported dystonic patients carrying VPS16 mutations displaying unusual phenotypic features in addition to dystonia, such as myoclonus, choreoathetosis, pharyngospasm and freezing of gait.

The Clinical Spectrum of ANO3-Report of a New Family and Literature Review.

Background: Mutations in ANO3 are a rare cause of autosomal dominant isolated or combined dystonia, mainly presenting in adulthood.

Cases: We extensively characterize a new, large ANO3 family with six affected carriers. The proband is a young girl who had suffered from tremor and painful dystonic movements in her right arm since the age of 11 years.

Ambroxol as a disease-modifying treatment to reduce the risk of cognitive impairment in -associated Parkinson's disease: a multicentre, randomised, double-blind, placebo-controlled, phase II trial. The AMBITIOUS study protocol.

Background: Heterozygous mutations in the gene, encoding the lysosomal enzyme β-glucocerebrosidase (GCase), are the most frequent genetic risk factor for Parkinson's disease (PD). -related PD (GBA-PD) patients have higher risk of dementia and reduced survival than non-carriers. Preclinical studies and one open-label trial in humans demonstrated that the chaperone ambroxol (ABX) increases GCase levels and modulates α-synuclein levels in the blood and cerebrospinal fluid (CSF).

Unraveling Autonomic Dysfunction in GBA-Related Parkinson's Disease.

Background: Patients with Parkinson's disease (PD) and gene mutations (GBA-PD) develop nonmotor complications more frequently than noncarriers. However, an objective characterization of both cardiovascular and sudomotor autonomic dysfunction using extensive clinical and instrumental measures has never been provided so far. Survival is reduced in GBA-PD regardless of age and dementia, suggesting that other hitherto unrecognized factors are involved.

Sex distribution and classification of GBA1 variants in an Italian cohort of Parkinson's disease patients analyzed over the last seventeen years.

Introduction: Heterozygous GBA1 variants are among the most frequent genetic risk factors for Parkinson's disease (PD). Male sex is a risk factor in the development of PD but the sex prevalence of GBA1 carriers in PD patients remains debatable. Molecular analysis of the GBA1 gene is complicated by the presence of a highly homologous pseudogene GBAP1.

Harmonizing Genetic Testing for Parkinson's Disease: Results of the PARKNET Multicentric Study.

Background And Objective: Early-onset Parkinson's disease (EOPD) commonly recognizes a genetic basis; thus, patients with EOPD are often addressed to diagnostic testing based on next-generation sequencing (NGS) of PD-associated multigene panels. However, NGS interpretation can be challenging in a diagnostic setting, and few studies have addressed this issue so far.

Methods: We retrospectively collected data from 648 patients with PD with age at onset younger than 55 years who underwent NGS of a minimal shared panel of 15 PD-related genes, as well as PD-multiplex ligation-dependent probe amplification in eight Italian diagnostic laboratories.

High Expression Negatively Correlates with Expression and Predicts Better Prognosis in Diffuse Large B-Cell Lymphoma: Role of Autophagy.

Diffuse large B-cell lymphoma (DLBCL) is characterized by high molecular and clinical heterogeneity. Autophagy, a lysosome-driven catabolic process devoted to macromolecular turnover, is fundamental in maintaining normal hematopoietic stem cells and progenitors homeostasis, and its dysregulation plays a critical role in the initiation and progression of hematological malignancies. One main regulator of autophagy is BECLIN-1, which may interact alternatively with either BCL-2, thus allowing apoptosis, or PI3KC3, thus promoting autophagy.
