Background: Hematopoietic cell transplantation (HCT) provides effective long-term management for some inborn errors of immunity. Genetic findings can inform donor selection, considerations in conditioning intensity and agents, and graft-versus-host disease prophylaxis. Exome/genome sequencing is increasingly accessible but of uncertain clinical utility.

Inborn errors of immunity (IEI) are rare heritable disorders of the immune system predisposing to atypical infections, autoimmunity, inflammation, and risk of malignancy. Adaptation is the process of incorporating stressful experiences into one's life; these experiences may include onset of illness, receiving a diagnosis, or suffering without a diagnosis. Poor adaptation is linked to adverse outcomes including psychiatric comorbidities and decreased well-being.

Background: Navigating the clinical literature to determine the optimal clinical management for rare diseases presents significant challenges. We introduce the Medical Action Ontology (MAxO), an ontology specifically designed to organize medical procedures, therapies, and interventions.

Methods: MAxO incorporates logical structures that link MAxO terms to numerous other ontologies within the OBO Foundry.

The Human Phenotype Ontology (HPO) is a widely used resource that comprehensively organizes and defines the phenotypic features of human disease, enabling computational inference and supporting genomic and phenotypic analyses through semantic similarity and machine learning algorithms. The HPO has widespread applications in clinical diagnostics and translational research, including genomic diagnostics, gene-disease discovery, and cohort analytics. In recent years, groups around the world have developed translations of the HPO from English to other languages, and the HPO browser has been internationalized, allowing users to view HPO term labels and in many cases synonyms and definitions in ten languages in addition to English.

Navigating the vast landscape of clinical literature to find optimal treatments and management strategies can be a challenging task, especially for rare diseases. To address this task, we introduce the Medical Action Ontology (MAxO), the first ontology specifically designed to organize medical procedures, therapies, and interventions in a structured way. Currently, MAxO contains 1757 medical action terms added through a combination of manual and semi-automated processes.

Article Synopsis
  • Researchers studied how certain genetic changes, called copy number variants (CNVs), affect immune system problems in kids.
  • They tested 332 children and found that many could be diagnosed using two types of genetic tests: exome sequencing (ES) and chromosomal microarray analysis (CMA).
  • Combining both tests helped doctors understand complicated cases better and sometimes find more than one issue causing the health problems.

Article Synopsis
  • This study focused on a holistic genetic evaluation of patients with immune-related issues, recognizing that multiple genetic factors might contribute to their health conditions rather than just a single gene explanation.
  • Researchers analyzed genetic data from 1505 individuals, uncovering 361 molecular diagnoses linked to various immune presentations, with significant updates obtained through reanalysis and new gene discoveries.
  • The findings indicate that the majority of molecular diagnoses could inform treatment options, highlighting the potential for whole exome analysis to enhance our understanding of genetic contributions to health on a large scale.

The most appropriate strategies for managing secondary genomic findings (SF) in clinical research are being developed and evaluated. We surveyed patients at the National Institute of Allergy and Infectious Diseases (NIAID) to evaluate decisional conflict regarding enrolling in a study that returns SF. Responses were collected using a cross-sectional survey after informed consent but before return of SF.

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare primary immunodeficiency disorder typically caused by homozygous mutations. It classically presents with chronic mucocutaneous candidiasis and autoimmunity that primarily targets endocrine tissues; hypoparathyroidism and adrenal insufficiency are most common. Developing any two of these classic triad manifestations establishes the diagnosis.

Purpose: The clinical immunology literature is punctuated with research on psychosocial dimensions of illness. Studies investigating the lived experiences and stated needs of patients with primary immune deficiencies and their families are essential to improving clinical management and determining the research questions that matter to patients and other stakeholders. Yet, to move the field forward, a systematic review of literature and proposed agenda is needed.
