    Case Study – Understanding Prader-Willi Syndrome

    Rare genetic disorders provide some of the best opportunities for students to see how multiple body systems work together. While many lessons teach genetics, the nervous system, or the endocrine system separately, Prader-Willi syndrome (PWS) demonstrates how a single genetic change can affect nearly every aspect of human physiology. This case study follows Ella, an…

  • Cystic Fibrosis – Overview and Genetics

    Cystic Fibrosis – Overview and Genetics

    Cystic fibrosis (CF) is a genetic disorder that affects the lungs, digestive system, and other parts of the body. Mutations in the CFTR gene on chromosome 7 leads to the production of thick, sticky mucus that can block airways and digestive ducts. Patients deal with lung infections and lack of nutrition because the mucus interferes…
