Common variable immunodeficiency (CVID) is a heterogeneous disorder characterized by antibody deficiency, poor humoral response to antigens, and recurrent infections. To investigate the molecular cause of CVID, we carried out exome sequence analysis of a family diagnosed with CVID and identified a heterozygous frameshift mutation, c.2564delA(More)
BACKGROUND The recombination-activating gene (RAG) 1/2 proteins play a critical role in the development of T and B cells by initiating the VDJ recombination process that leads to generation of a broad T-cell receptor (TCR) and B-cell receptor repertoire. Pathogenic mutations in the RAG1/2 genes result in various forms of primary immunodeficiency, ranging(More)
Phevor integrates phenotype, gene function, and disease information with personal genomic data for improved power to identify disease-causing alleles. Phevor works by combining knowledge resident in multiple biomedical ontologies with the outputs of variant-prioritization tools. It does so by using an algorithm that propagates information across and between(More)
Patients with mutations of the recombination-activating genes (RAG) present with diverse clinical phenotypes, including severe combined immune deficiency (SCID), autoimmunity, and inflammation. However, the incidence and extent of immune dysregulation in RAG-dependent immunodeficiency have not been studied in detail. Here, we have demonstrated that patients(More)
Preterm birth (PTB), defined as birth prior to a gestational age (GA) of 37 completed weeks, affects more than 10 % of births worldwide. PTB is the leading cause of neonatal mortality and is associated with a broad spectrum of lifelong morbidity in survivors. The etiology of spontaneous PTB (SPTB) is complex and has an important genetic component. Previous(More)
BACKGROUND Therapeutic options for DiGeorge syndrome (DGS) with profound T-cell deficiency are very limited. Thymic transplantation has shown promising results but is not easily available. Hematopoietic cell transplantation (HCT) has been successful in restoring immune competence in the short term. OBJECTIVE Present the long-term follow-up of 2 patients(More)
To the Editor: A growing body of literature demonstrates that recombinase activating gene (RAG1/2) deficiency is seen in patients with autoimmune features and variable immunodeficiency, thus expanding the phenotype beyond T/B/natural killer severe combined immunodeficiency (SCID) and Omenn syndrome (OS). Based on data from SCID newborn screening programs in(More)
BACKGROUND PRKDC encodes for DNA-dependent protein kinase catalytic subunit (DNA-PKcs), a kinase that forms part of a complex (DNA-dependent protein kinase [DNA-PK]) crucial for DNA double-strand break repair and V(D)J recombination. In mice DNA-PK also interacts with the transcription factor autoimmune regulator (AIRE) to promote central T-cell tolerance.(More)
The current global epidemic of atopy and asthma has been related to the changes in environmental exposures brought about by the development and expansion of industrialized societies. This article reviews the evidence supporting the fundamental role of air pollutants in fostering allergic inflammation of the airways, with emphasis on the molecular and(More)
