Scientists uncover genetic secrets behind rare hormone disorders
Knowledge-focused CompletedThis study looked at nearly 1,400 people with rare conditions like PPNAD, Carney Complex, and Peutz-Jeghers syndrome. The goal was to find the genetic causes and link them to specific symptoms. Researchers used clinical exams and genetic testing to better understand how these dis…

Researchers track rare hormone disorder in 133 patients
Knowledge-focused CompletedThis study followed 133 people with PPNAD (a rare adrenal gland disorder) or Carney Complex (a related genetic condition) for three years. The goal was to better understand the symptoms and genetic causes of these diseases, not to test a new treatment. Participants had yearly che…
