Variants in the AGBL5 gene are responsible for autosomal recessive Retinitis pigmentosa with hearing loss.

The AGBL5 gene encodes for the Cytoplasmic Carboxypeptidase 5 (CCP5), an α-tubulin deglutamylase that cleaves the γ-carboxyl-linked branching point of glutamylated tubulin. To date, pathogenic variants in AGBL5 have been associated only with isolated retinitis pigmentosa (RP). Hearing loss has not been reported in AGBL5-caused retinal disease.

Joint contractures is a recurrent clinical feature of individuals with neurodevelopmental disorder due to FOXP1 likely gene disruptive variants.

Haploinsufficiency of FOXP1 gene is responsible for a neurodevelopmental disorder presenting with intellectual disability (ID), autism spectrum disorder (ASD), hypotonia, mild dysmorphic features, and multiple congenital anomalies. Joint contractures are not listed as a major feature of FOXP1-related disorder. We report five unrelated individuals, each harboring likely gene disruptive de novo FOXP1 variants or whole gene microdeletion, who showed multiple joint contractures affecting at least two proximal and/or distal joints.

Whole genome sequencing identifies elusive variants in genetically unsolved Italian inherited retinal disease patients.

Inherited retinal diseases (IRDs) are a group of rare monogenic diseases with high genetic heterogeneity (pathogenic variants identified in over 280 causative genes). The genetic diagnostic rate for IRDs is around 60%, mainly thanks to the routine application of next-generation sequencing (NGS) approaches such as extensive gene panels or whole exome analyses. Whole-genome sequencing (WGS) has been reported to improve this diagnostic rate by revealing elusive variants, such as structural variants (SVs) and deep intronic variants (DIVs).

Digital health and Clinical Patient Management System (CPMS) platform utility for data sharing of neuromuscular patients: the Italian EURO-NMD experience.

Background: The development of e-health technologies for teleconsultation and exchange of knowledge is one of the core purposes of European Reference Networks (ERNs), including the ERN EURO-NMD for rare neuromuscular diseases. Within ERNs, the Clinical Patient Management System (CPMS) is a web-based platform that seeks to boost active collaboration within and across the network, implementing data sharing. Through CPMS, it is possible to both discuss patient cases and to make patients' data available for registries and databases in a secure way.

A new genetic cause of spastic ataxia: the p.Glu415Lys variant in TUBA4A.

Tubulinopathies encompass neurodevelopmental disorders caused by mutations in genes encoding for different isotypes of α- and β-tubulins, the structural components of microtubules. Less frequently, mutations in tubulins may underlie neurodegenerative disorders. In the present study, we report two families, one with 11 affected individuals and the other with a single patient, carrying a novel, likely pathogenic, variant (p.

Genetic epidemiology of inherited retinal diseases in a large patient cohort followed at a single center in Italy.

Inherited retinal diseases (IRDs) are the leading cause of vision loss in the working-age population. We performed a retrospective epidemiological study to determine the genetic basis of IRDs in a large Italian cohort (n = 2790) followed at a single referral center. We provided, mainly by next generation sequencing, potentially conclusive molecular diagnosis for 2036 patients (from 1683 unrelated families).

The position of nonsense mutations can predict the phenotype severity: A survey on the DMD gene.

A nonsense mutation adds a premature stop signal that hinders any further translation of a protein-coding gene, usually resulting in a null allele. To investigate the possible exceptions, we used the DMD gene as an ideal model. First, because dystrophin absence causes Duchenne muscular dystrophy (DMD), while its reduction causes Becker muscular dystrophy (BMD).

High Somatic Mutation and Neoantigen Burden Do Not Correlate with Decreased Progression-Free Survival in HCC Patients not Undergoing Immunotherapy.

Cancer genome instability leads to accumulation of mutations which may result into tumor-specific mutated "neoantigens", not be affected by central T-cell tolerance. Such neoantigens are considered the optimal target for the patient's anti-tumor T cell immunity as well as for personalized cancer immunotherapy strategies. However, only a minor fraction of predicted neoantigens are relevant to the clinical outcome.
