| Associated to the scholarship: | 22/03428-0 - Search for genetic variants with pathogenic potential in patients with a characteristic phenotype of coesinopathies focusing on the Cornelia de Lange Syndrome, BP.DD |
Abstract Cornelia de Lange Syndrome (CdLS) is a rare disorder (RD) that affects 1 in 45,000 to 1 in 62,000 live births and has several physical, cognitive, and behavioral phenotypes. Although CdLS patients frequently have a typical facial phenotype that can help during the search for a diagnostic, some of them remain molecularly undiagnosed for many years due to factors such as mosaic mutations or variants that cannot be confirmed as pathogenic due to the lack of functional studies and in silico tools. The diagnostic odyssey for patients with rare disorders can be related to health and financial consequences for both patients and parents. Many tools have been developed in the last years to accelerate this process and help both clinicians and laboratories while searching for variants that can explain these patients' phenotypes. Next-generation phenotyping (NGP) is a growing methodology that can help during the phenotypic interpretation of RD patients. Therefore, this study aims to prioritize CdLS patients who have already undergone several exams for further exams, through performing a neural network and clustering analysis with photos of patients already molecularly diagnosed for CdLS and providing a software that can perform this analysis for other RD. Moreover, we also aim to use NGP to produce a facial phenotype score to aid during variant classification. Results obtained by this project can accelerate the diagnostic odyssey of RD patients. | |
