Implementation of a gene panel for genetic diagnosis of primary ciliary dyskinesia

Abstract Introduction Primary ciliary dyskinesia (PCD) is characterized by an alteration in the ciliary structure causing difficulty in the clearance of respiratory secretions. Diagnosis is complex and based on a combination of techniques. The objective of this study was to design a gene panel including all known causative genes, and to corroborate their diagnostic utility in a cohort of Spanish patients. Methods This was a multicenter cross-sectional study of patients with a high suspicion of PCD according to European Respiratory Society criteria. We designed a gene panel for massive sequencing using SeqCap EZ capture technology that included 44 genes associated with PCD. Results We includ…

Implementación de un panel de genes para el diagnóstico genético de la discinesia ciliar primaria

Resumen Introduccion La discinesia ciliar primaria (DCP) es una enfermedad caracterizada por una alteracion en la estructura ciliar que impide el correcto aclaramiento de las secreciones respiratorias. Su diagnostico es complejo y se basa en una combinacion de tecnicas. El objetivo de este estudio fue disenar un panel de genes incluyendo todos los genes causantes conocidos y comprobar su utilidad diagnostica en una cohorte de pacientes espanoles. Metodos Estudio transversal multicentrico de pacientes con sospecha elevada de DCP, aplicando los criterios de la European Respiratory Society. Diseno de un panel de genes para secuenciacion masiva con la tecnologia de captura SeqCap EZ technology,…

Genome-wide variant calling in reanalysis of exome sequencing data uncovered a pathogenic TUBB3 variant.

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…

Implementation of a gene panel for the genetic diagnosis of primary ciliary dyskinesia

Background: Primary ciliary dyskinesia (PCD) is a disease characterized by an alteration in the ciliary structure that causes an abnormal clearance of respiratory secretions. Its diagnosis is complex and is based on a combination of different techniques. The objective of this study was to design a gene panel including all known caustive genes, and to verify the utility for diagnostic in a cohort of Spanish patients. Methods: Multicenter cross-sectional study of patients with high suspicion of PCD, applying the criteria of the European Respiratory Society. Design a gene panel for mass sequencing with SeqCap EZ technology, including 44 PCD-related genes. Results: 79 patients were included, 53…
