At its core, pathology is the study of disease. Diseases occur for many reasons. But some, such as cystic fibrosis and Parkinson’s Disease, occur because of alterations that prevent cells from functioning normally. Understanding signals and symptoms of alterations in cellular processes is a critical step in the diagnosis and treatment of many diseases. For the Advanced Practice Registered Nurse (APRN), this understanding can also help educate patients and guide them through their treatment plans. For this Discussion, you examine a case study and explain the disease that is suggested. You examine the symptoms reported and explain the cells that are involved and potential alterations and impacts.    QUESTION Describe the role genetics plays in the disease process of Streptococcus group A   Why are patients with Streptococcus throat present with specific symptoms such as sore throat, reddened posterior pharynx with white exudate on tonsils that are enlarged to 3+, Positive anterior and posterior cervical adenopathy? What is the physiologic response to the stimulus presented in the scenario and why do you think this response occurred? What are the cells that are involved in this process? How would another characteristic (e.g., gender, genetics) change your response? ReadingMaterials.docx
