Symptoms include neonatal respiratory distress, chronic sinusitis, bronchiectasis, situs inversus, and infertility. Clinical features may be subtle and highly variable, making the diagnosis of PCD challenging. The diagnosis can be confirmed with ciliary ultrastructure analysis and\/or molecular genetic testing of 32 PCD-associated genes. However, because of this genetic heterogeneity, comprehensive molecular genetic testing is not considered the standard of care, and the most efficient molecular approach has yet to be elucidated. Here, we propose a cost-effective and time-efficient molecular genetic algorithm to solve cases of PCD. We conducted targeted copy number variation (CNV) analysis and\/or whole-exome sequencing on 20 families (22 patients) from a subset of 45 families (52 patients) with a clinical diagnosis of PCD who did not have a molecular genetic diagnosis after Sanger sequencing of 12 PCD-associated genes. This combined molecular genetic approach led to the identification of 4 of 20 (20%) families with clinically significant CNVs and 7 of 20 (35%) families with biallelic pathogenic mutations in recently identified PCD genes, resulting in an increased molecular genetic diagnostic rate of 55% (11\/20). In patients with a clinical diagnosis of PCD, whole-exome sequencing followed by targeted CNV analysis results in an overall molecular genetic yield of 76% (34\/45).<\/jats:p>","DOI":"10.1534\/g3.115.019851","type":"journal-article","created":{"date-parts":[[2015,7,9]],"date-time":"2015-07-09T16:00:35Z","timestamp":1436457635000},"page":"1775-1781","source":"Crossref","is-referenced-by-count":68,"title":["Whole-Exome Sequencing and Targeted Copy Number Analysis in Primary Ciliary Dyskinesia"],"prefix":"10.1093","volume":"5","author":[{"given":"Christian R","family":"Marshall","sequence":"first","affiliation":[{"name":"Department of Pediatric Laboratory Medicine, The Hospital for Sick Children, Toronto, ON, M5G 1X8, Canada"},{"name":"The Centre for Applied Genomics, Genetics and Genome Biology, The Hospital for Sick Children, Toronto, ON, M5G 1X8, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen W","family":"Scherer","sequence":"additional","affiliation":[{"name":"The Centre for Applied Genomics, Genetics and Genome Biology, The Hospital for Sick Children, Toronto, ON, M5G 1X8, Canada"},{"name":"Department of Molecular Genetics and the McLaughlin Centre, University of Toronto, Toronto, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maimoona A","family":"Zariwala","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, University of North Carolina School of Medicine, Chapel Hill, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lynette","family":"Lau","sequence":"additional","affiliation":[{"name":"Department of Pediatric Laboratory Medicine, The Hospital for Sick Children, Toronto, ON, M5G 1X8, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tara A","family":"Paton","sequence":"additional","affiliation":[{"name":"The Centre for Applied Genomics, Genetics and Genome Biology, The Hospital for Sick Children, Toronto, ON, M5G 1X8, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tracy","family":"Stockley","sequence":"additional","affiliation":[{"name":"Department of Pediatric Laboratory Medicine, The Hospital for Sick Children, Toronto, ON, M5G 1X8, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rebekah K","family":"Jobling","sequence":"additional","affiliation":[{"name":"Division of Clinical and Metabolic Genetics, The Hospital for Sick Children, Toronto, ON, M5G 1X8, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter N","family":"Ray","sequence":"additional","affiliation":[{"name":"Department of Pediatric Laboratory Medicine, The Hospital for Sick Children, Toronto, ON, M5G 1X8, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael R","family":"Knowles","sequence":"additional","affiliation":[{"name":"Department of Medicine, University of North Carolina School of Medicine, Chapel Hill, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"FORGE Canada Consortium","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David A","family":"Hall","sequence":"additional","affiliation":[{"name":"Department of Pediatric Laboratory Medicine, The Hospital for Sick Children, Toronto, ON, M5G 1X8, Canada"},{"name":"Division of Respirology, St. Michael\u2019s Hospital, Toronto, ON, M5B 1W8, Canada"},{"name":"Department of Medicine, University of Toronto, Toronto, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sharon D","family":"Dell","sequence":"additional","affiliation":[{"name":"Child Health Evaluative Sciences, The Hospital for Sick Children, Toronto, ON, M5G 1X8, Canada"},{"name":"Division of Respiratory Medicine, The Hospital for Sick Children, Toronto, ON, M5G 1X8, Canada"},{"name":"Department of Pediatrics, University of Toronto, Toronto, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raymond H","family":"Kim","sequence":"additional","affiliation":[{"name":"Division of Clinical and Metabolic Genetics, The Hospital for Sick Children, Toronto, ON, M5G 1X8, Canada"},{"name":"Department of Medicine, University of Toronto, Toronto, ON, Canada"},{"name":"Department of Pediatrics, University of Toronto, Toronto, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2015,8,1]]},"reference":[{"key":"2021042112034281900_bib1","doi-asserted-by":"crossref","first-page":"594","DOI":"10.1038\/gim.2011.65","article-title":"Exon-level array CGH in a large clinical cohort demonstrates increased sensitivity of diagnostic testing for Mendelian disorders.","volume":"14","author":"Aradhya","year":"2012","journal-title":"Genet.
