Article Synopsis
- The study investigates a specific genetic variant in the IP3 receptor that results in a significant disorder affecting multiple systems, characterized by immunodeficiency and disturbed calcium release in cells.
- The variant (c.7570C>T, p.Arg2524Cys) leads to cellular defects, particularly impacting T cells, and is shown to affect calcium regulation and mitochondrial function, evidenced in laboratory models.
- Patients exhibited a range of symptoms beyond immunodeficiency, such as ectodermal dysplasia and short stature, suggesting that this genetic mutation plays a unique and broader role in disease compared to previously documented cases.
This study aimed to evaluate and compare the performance of three anti-S and one anti-N assays that were available to the project in detecting antibody levels after three commonly used SARS-CoV-2 vaccines (Pfizer, Moderna, and Johnson & Johnson). It also aimed to assess the association of age, sex, race, ethnicity, vaccine timing, and vaccine side effects on antibody levels in a cohort of 827 individuals. In September 2021, 698 vaccinated individuals donated blood samples as part of the Association for Diagnostics & Laboratory Medicine (ADLM) COVID-19 Immunity Study.

- In 2021, the Association for Diagnostics & Laboratory Medicine (ADLM) conducted a study to enhance the understanding of immunity against SARS-CoV-2 amid the pandemic.
- The study involved survey responses from 975 individuals and blood samples from 698 of them, showcasing a significant level of participation.
- The paper details the design, implementation, and valuable insights gained from conducting this extensive scientific investigation.
Primary immunodeficiencies were initially identified on the basis of recurrent, severe or unusual infections. Subsequently, it was noted that these diseases can also manifest with autoimmunity, autoinflammation, allergy, lymphoproliferation and malignancy, hence a conceptual change and their renaming as inborn errors of immunity. Ongoing advances in flow cytometry provide the opportunity to expand or modify the utility and scope of existing laboratory tests in this field to mirror this conceptual change.

Design And Methods: A cohort of 677 vaccinated individuals participated in a comprehensive survey of their vaccination status and associated side effects, and donated blood to evaluate their adaptive immune responses by neutralizing antibody (NAb) and T cell responses. The cohort then completed a follow-up survey to investigate the occurrence of breakthrough infections.
