Prospective interest in deploying multi-omics approaches to solve unsolved patients with suspected monogenic developmental delay syndromes

Genome-wide variant calling in reanalysis of exome sequencing data uncovered a pathogenic TUBB3 variant.
2021
Almost half of all individuals affected by intellectual disability (ID) remain undiagnosed. In the Solve-RD project, exome sequencing (ES) datasets from unresolved individuals with (syndromic) ID (n = 1,472 probands) are systematically reanalyzed, starting from raw sequencing files, followed by genome-wide variant calling and new data interpretation. This strategy led to the identification of a disease-causing de novo missense variant in TUBB3 in a girl with severe developmental delay, secondary microcephaly, brain imaging abnormalities, high hypermetropia, strabismus and short stature. Interestingly, the TUBB3 variant could only be identified through reanalysis of ES data using a genome-wi…
P09.084C - Strong interest of exome sequencing in progressive neurological diseases
2019
International audience; Introduction: Neurogenetics represents a vast, complex, ever changing discipline whose diagnosis currently remains challenging, since clinical and/or imaging features frequently appear very unspecific, especially early in the evolution (cerebellar ataxia, tremor, dystonia...). In molecular diagnosis, current strategies usually include sequential investigations that may lead to long, tedious, expensive and disappointing patients care. Exome sequencing (ES) appears a promising approach for neurogenetics, apart from when nucleotide motif expansion disorders can be suspected. Materials and Methods: We recruited 48 individuals without cognitive development impairment, ref…
