Post an explanation of the disease highlighted in the scenario you were provided. Include the following in your explanation, usually a paragraph with citation(s) should suffice to cover each point. Citations would reflect classroom textbook, primary, current peer-reviewed journal articles (published in last 5 yr) usually, 3 will support your points.Cellular Processes and the Genetic Environment Essay

• The role genetics plays in the disease.
• Why the patient is presenting with the specific symptoms described.
• The physiologic response to the stimulus presented in the scenario and why you think this response occurred.
• The cells that are involved in this process.
• How another characteristic (e.g., gender, genetics) would change your response.
