Texte intégralNeurological diseases are a heterogeneous group of pathologies characterized, in many cases, by a strong clinical and genetic heterogeneity. Examples of this are spastic paraplegia and ataxia, in which the genetic component is in many cases difficult to frame. While many of these patients fail to identify this component, others receive a clinical diagnosis in which the gene responsible for the phenotype is identified. In such patients, genetic analysis must regard the incomplete penetrance, and the presence of "private" mutations (described only in some families). Moreover, the difficulty in carrying out multicentric studies with homogeneously selected patients makes it difficult to develop specific databases in which the gene variants are reported, and the clinical phenotype associated with them. Regarding the phenotype, the clinical and molecular diagnostics find more difficulties in the most complex forms, in which spasticity or ataxia are only a component of much more complex clinical syndrome. Next Generation Sequencing (NGS) technologies have solved the problem of "polygenicity", making it possible to analyze multiple genes simultaneously, including the analysis of the whole genome. To date, carefully designed and validated panels have become part of clinical practice. The application of these technologies in neurological diseases is more complex because it requires a careful selection of genes to be analyzed. Moreover, considering the high allelic heterogeneity, it is difficult to establish a correct detection rate (% of identified positives), and therefore to develop easy-to-use panels in molecular diagnostics. In light of these observations, the thesis had the following objectives: • Design, develop and validate a panel of genes based on NGS technology (NGS target panel) for the diagnosis of patients characterized by ataxia and / or spasticity • To evaluate the usefulness of the NGS analysis of all the coding genes associated with Mendelian pathologies (clinical exome) for a correct classification of complex neurological phenotypes. The study was conducted on 78 ataxic and / or spastic patients recruited at the IRCCS Neuromed. The genetic component potentially responsible for the clinical phenotype was identified in 21% of the patients analyzed by the target NGS Panel, and in 13% of the patients analyzed by clinical exome. The study showed that NGS panels, carefully designed and validated, can be applied to the molecular diagnosis of neurological pathologies characterized by polygenicity and clinical variability. The validation of these clinical strategies requires the careful and homogeneous selection of the cases. This allows to delineate the correct diagnostic use, thus increasing the detection rate. It is also essential to use a very stringent and reproducible interpretation of the variants. This is confirmed in the present study, where the joint use of family segregation analysis (where possible) and bioinformatics analysis, is fundamental for the identification of pathological variants. For a correct diagnostic classification of the complex phenotypes it was useful to apply larger panels, such as the clinical exome.

Texte intégralThe work I carried out during my PhD studies has been aimed to identify and characterize disease genes associated with rare neurological disorders. In particular I worked on phenotypic and molecular characterization of two patients with an atypical neuroaxonal dystrophy presentation, in which a homozygous mutation within the TFG gene has been identified by mean of WES (whole exome sequencing) technology. Besides, I also studied three unrelated families with individuals affected by Leigh syndrome and carrying the same biallelic mutations in the NDUFAF6 gene. The identification of a novel intronic variant has been integrated with its functional validation through mRNA analysis. I also described two cases with complex clinical neurodegenerative phenotypes. Phenotypic characterization has been integrated the identification of two novel mutations in already reported disease genes, respectively DNMT1 and OTX2. In the patient with OTX2 mutation, molecular and clinical presentation remains not entirely explained by a single gene mutation and additional possible genetic modifiers were found. This case represents an example of how detailed collection of clinical data and family history in parallel to NGS data analysis is often helpful in order to identify composite genotypes sometimes associated with complicated inherited syndromes. Additionally, as a partner of the European international network for mitochondrial disorders, I was also involved in the GENOMIT project; within this framework, I dedicated the last few months of my PhD to investigate the feasibility of a promising xenotopic genetic therapy for Leigh syndrome and other neurological conditions associated with mitochondrial complex I deficiency, using engineered patient fibroblasts as a cellular model of disease.
