Primary Ciliary Dyskinesia (PCD) is a rare heterogeneous genetic disorder affecting motile cilia structure and function leading to lung disease. We generated induced pluripotent stem cells (iPSCs) from dermal fibroblasts of a female PCD patient carrying disease-causing variants in the CCDC40 gene. Reprogramming was performed with the human OSKM transcription factors using the Sendai-virus delivery system. The resulting transgene free iPSCs had normal karyotype, expressed pluripotency markers, could differentiate into the three germ layers in vivo and retained the disease-causing CCDC40 mutations...

Primary ciliary dyskinesia (PCD) can manifest in the neonatal period with severe respiratory distress. We describe a child with PCD who presented at term with severe neonatal respiratory distress, persistent right upper lobe collapse and failure to thrive who underwent lobectomy prior to the diagnosis of PCD at the age of 3 years. This case report illustrates the severe spectrum of lung disease associated with coiled-coil domain containing protein 40 (CCDC40) gene variants in patients with PCD.

Purpose: Primary ciliary dyskinesia (PCD) is a rare genetic disorder manifested with recurrent infections of respiratory tract and infertility. Mutations in more than 20 genes including the Coiled-Coil Domain Containing 40 ( CCDC40 ) gene are associated with PCD. A Chinese proband with a clinical diagnosis of PCD was analyzed for mutations in these genes to identify the genetic basis of the disease in the family. The proband showed altered mucociliary clearance of the airways, various degree of hyperemia and edema of the mucous membrane, left/right body asymmetry, infertility and ultrastructural abnormality of cilia in both sperm and bronchioles...

Leftward fluid flow in the mouse node is generated by cilia and is critical for initiating asymmetry of the left-right axis. Coiled-coil domain containing-40 (Ccdc40) plays an evolutionarily conserved role in the assembly of motile cilia and establishment of the left-right axis. Approximately one-third of Ccdc40lnks mutant embryos display situs defects and here we investigate the underlying mechanism. Ccdc40lnks mutants show delayed induction of markers of the left-lateral plate mesoderm (L-LPM) including Lefty1, Lefty2 and Nodal...

Small-cell gallbladder neuroendocrine carcinoma (GB-SCNEC) is a relatively rare histological type of gallbladder cancer, and the genomic landscape of GB-SCNEC is rarely considered in treatment decisions. We performed whole-genome sequencing on an advanced case of GB-SCNEC. We identified approximately 900 high-quality somatic single nucleotide variants (SNVs) and small insertions and deletions (INDELs), 109 of which were shared by both the primary and metastatic tumor tissues. Somatic non-synonymous coding variations with damaging impact in HMCN1 and CDH10 were observed in both the primary and metastatic tissue specimens...

Primary ciliary dyskinesia (PCD) is an autosomal recessive disease characterized by chronic respiratory infections of the upper and lower airways, hypofertility, and, in approximately half of the cases, situs inversus. This complex phenotype results from defects in motile cilia and sperm flagella. Among the numerous genes involved in PCD, very few-including CCDC39 and CCDC40-carry mutations that lead to a disorganization of ciliary axonemes with microtubule misalignment. Focusing on this particular phenotype, we identified bi-allelic loss-of-function mutations in GAS8, a gene that encodes a subunit of the nexin-dynein regulatory complex (N-DRC) orthologous to DRC4 of the flagellated alga Chlamydomonas reinhardtii...

CCDC39 and CCDC40 were first identified as causative mutations in primary ciliary dyskinesia patients; cilia from patients show disorganized microtubules, and they are missing both N-DRC and inner dynein arms proteins. In Chlamydomonas, we used immunoblots and microtubule sliding assays to show that mutants in CCDC40 (PF7) and CCDC39 (PF8) fail to assemble N-DRC, several inner dynein arms, tektin, and CCDC39. Enrichment screens for suppression of pf7; pf8 cells led to the isolation of five independent extragenic suppressors defined by four different mutations in a NIMA-related kinase, CNK11...

PURPOSE: Perform the genetic characterization of five patients with total sperm immotility using Sanger sequencing and Whole Exome Sequencing (WES), in order to increase the knowledge on the genetics of sperm immotility and, ultimately, allow the identification of potential genetic markers for infertility. METHODS: Prospective study at a University Medical school. We analysed five men with total sperm immotility, four with dysplasia of the fibrous sheath (DFS), associated with disruption of several axonemal structures, and one patient with situs inversus totalis, which showed absence of dynein arms (DA) and nexin bridges...

Primary ciliary dyskinesia (PCD) is a genetically heterogeneous, autosomal recessive disorder that results from functional and ultrastructural abnormalities of motile cilia. Patients with PCD have diverse clinical phenotypes that include chronic upper and lower respiratory tract infections, situs inversus, heterotaxy with or without congenital heart disease, and male infertility, among others. In this report, the carrier frequencies for eleven mutations in eight PCD-associated genes (DNAI1, DNAI2, DNAH5, DNAH11, CCDC114, CCDC40, CCDC65, and C21orf59) that had been found in individuals of Ashkenazi Jewish descent were investigated in order to advise on including them in existing clinical mutation panels for this population...

BACKGROUND AND AIMS: Primary ciliary dyskinesia (PCD) is a rare, genetically heterogeneous disorder. Genetic defects affecting motility of cilia and flagella cause chronic destructive airway disease, situs inversus and, frequently, male infertility in PCD. To date, although several genes have been implicated in PCD, the genetic bases of most cases of PCD remain elusive. METHODS: By applying a whole-exome sequencing strategy, we reported a case of PCD carrying a novel mutant alleles in CCDC40 gene, and did literature review...

Primary ciliary dyskinesia (PCD) is a rare genetic disorder leading to recurrent respiratory tract infections. High-speed video-microscopy analysis (HVMA) of ciliary beating, currently the first-line diagnostic tool for PCD in most centres, is challenging because recent studies have expanded the spectrum of HVMA findings in PCD from grossly abnormal to very subtle. The objective of this study was to describe the diversity of HVMA findings in genetically confirmed PCD individuals. HVMA was performed as part of the routine work-up of individuals with suspected PCD...

When Chlamydomonas cells resorb their flagella, seven polypeptides become asymmetrically dimethylated (aDMA) on arginine residues. Tandem mass spectrometry has identified these as radial spoke proteins 1, 2, 5, and 6; tektin, a structural component of the outer doublets; and flagellar-associated protein 172 (FAP172) (coiled-coil domain containing protein 40 (CCDC40)) and FAP250 (CCDC65), which are associated with inner arm dynein and the nexin-dynein regulatory complex. The enzyme protein arginine methyl transferase 1 (PRMT1), which generates aDMA residues, is a component of the flagellar matrix; antibodies to PRMT1 label full-length flagella in a punctate pattern along the length of the axoneme...

Pompe disease is an uncommon autosomal recessive glycogen storage disorder caused by deficiency of acid α-glucosidase. Classic infantile form triggers severe cardiomyopathy, hypotonia, and respiratory failure, leading to death within the first two years of life. The majority of patients with Pompe disease have been reported to have point mutations in the GAA gene. We report the first complex deletion-insertion encompassing the complete structure of GAA gene and a large fragment of the gene CCDC40 in a patient with very severe form of Pompe disease...

Primary ciliary dyskinesia (PCD) is a genetically heterogeneous disorder caused by cilia and sperm dysmotility. About 12% of cases show perturbed 9+2 microtubule cilia structure and inner dynein arm (IDA) loss, historically termed "radial spoke defect." We sequenced CCDC39 and CCDC40 in 54 "radial spoke defect" families, as these are the two genes identified so far to cause this defect. We discovered biallelic mutations in a remarkable 69% (37/54) of families, including identification of 25 (19 novel) mutant alleles (12 in CCDC39 and 13 in CCDC40)...

BACKGROUND: CCDC39 and CCDC40 genes have recently been implicated in primary ciliary dyskinesia (PCD) with inner dynein arm (IDA) defects and axonemal disorganisation; their contribution to the disease is, however, unknown. Aiming to delineate the CCDC39/CCDC40 mutation spectrum and associated phenotypes, this study screened a large cohort of patients with IDA defects, in whom clinical and ciliary phenotypes were accurately described. METHODS: All CCDC39 and CCDC40 exons and intronic boundaries were sequenced in 43 patients from 40 unrelated families...
