Primary ciliary dyskinesia most often arises from loss of the dynein motors that power ciliary beating. Here we show that DNAAF3 (also known as PF22), a previously uncharacterized protein, is essential for the preassembly of dyneins into complexes before their transport into cilia. We identified loss-of-function mutations in the human DNAAF3 gene in(More)
Primary ciliary dyskinesia (PCD) is a genetically heterogeneous disorder characterized by chronic destructive airway disease and randomization of left/right body asymmetry. Males often have reduced fertility due to impaired sperm tail function. The complex PCD phenotype results from dysfunction of cilia of the airways and the embryonic node and the(More)
OBJECTIVES Treatment with pancreatic enzymes fails to completely correct malabsorption and gastrointestinal symptoms in patients with cystic fibrosis (CF). The aim of the present study was to examine the small intestine of patients with CF without overt evidence of gastrointestinal disease using capsule endoscopy (CE). METHODS Patients with CF received(More)
OBJECTIVES Most patients with cystic fibrosis (CF) have pancreatic insufficiency; however, 15% of the patients are pancreatic sufficient (PS). Several laboratory tests have been developed to distinguish between pancreatic insufficiency and PS. The gold standard to determine pancreatic function apart from direct pancreatic stimulation test is the 72-hour(More)
Aberrant nucleic acids generated during viral replication are the main trigger for antiviral immunity, and mutations that disrupt nucleic acid metabolism can lead to autoinflammatory disorders. Here we investigated the etiology of X-linked reticulate pigmentary disorder (XLPDR), a primary immunodeficiency with autoinflammatory features. We discovered that(More)
BACKGROUND Nontuberculous mycobacteria (NTM) are emerging infections in the CF population. AIMS To assess NTM infection prevalence and associated features in our CF clinic population. METHODS Patient records, 2002-2011, were reviewed for NTM infection. FEV1, pancreatic function, sputum microbiology, and serum cytokines were compared in patients with and(More)
BACKGROUND Congenital bilateral absence of the vas deferens (CBAVD) is presumed to occur prenatally and is present in over 99% of adult males with cystic fibrosis (CF). AIMS To describe ultrasonic features in male children with CF. We aimed to describe urogenital anomalies, comparing pancreatic sufficient and insufficient CF patients. METHODS Pelvic and(More)
BACKGROUND Cystic fibrosis is no longer a terminal illness of childhood and mean survival is now over 30 years. Adult patients with atypical CF are increasingly being diagnosed. In Israel, all patients are still followed in pediatric centers. OBJECTIVES To describe our experience with adult CF, stressing the importance of adult-related health and(More)
Intracranial pressure was continuously monitored in 23 patients aged between 24 hours and 20 months. Fourteen had severe infections of the central nervous system (CNS) and 9 sustained prolonged cerebral ischaemia. The intracranial pressure measured at catheter placement was not a reliable indicator of the intracranial pressure that developed during the(More)
The killing of natural killer (NK) cells is regulated by activating and inhibitory NK receptors that recognize mainly class I major histocompatibility complex (MHC) proteins. In transporter associated with antigen processing (TAP2)-deficient patients, killing of autologous cells by NK cells is therefore expected. However, none of the TAP2-deficient patients(More)
