This study analyzed DNA from 9 patients with primary immune deficiencies whose genetic cause was unknown. Researchers used whole exome or genome sequencing to look for new mutations that might explain their condition. The goal was to identify new inborn errors of immunity, which …

This study looked for hidden immune system problems in adults who get frequent or severe bacterial infections, like pneumonia or meningitis. Researchers screened 120 adults aged 18-65 to see how many had an undiagnosed primary immunodeficiency. The goal was to find out if these c…
