INTRODUCTION Good afternoon everyone, and thank you for joining us today for this presentation on chromosomal abnormalities and inborn errors of metabolism. As you may know, chromosomal abnormalities and inborn errors of metabolism are genetic disorders that can affect individuals from birth and throughout their lives. They can cause a range of physical, cognitive, and developmental challenges, and can be difficult to manage without early diagnosis and proper treatment. In this presentation, we will explore some of the most common chromosomal abnormalities, including trisomy 13, trisomy 18, and trisomy 2, as well as the birth defect phocomelia. We will also discuss inborn errors of metabolism, such as phenylketonuria (PKU), and the importance of early diagnosis and management. I hope this presentation will be informative and useful for you, whether you are a healthcare provider, a student, or someone who is interested in learning more about these conditions. Thank you again for being here, and let's get started! Chromosomal abnormalities and inborn errors of metabolism are two categories of genetic disorders that can significantly impact an individual's health and quality of life. Chromosomal abnormalities occur when there are changes in the number or structure of chromosomes, leading to developmental and physical abnormalities (National Human Genome Research Institute, 2021). Inborn errors of metabolism, on the other hand, result from a genetic defect that disrupts the body's ability to process certain substances, leading to a buildup of toxic substances and a wide range of symptoms (National Institutes of Health, 2021). Early diagnosis and management of these conditions are crucial in preventing long-term complications and improving patient outcomes. Timely diagnosis and treatment of chromosomal abnormalities and inborn errors of metabolism can prevent or minimize symptoms, improve growth and development, and enhance overall quality of life for affected individuals. According to the American College of Medical Genetics and Genomics, "Early diagnosis of genetic disorders through newborn screening and prenatal diagnosis is critical for timely and appropriate interventions to improve outcomes for affected individuals" (ACMG, 2013). As nurses, we play a critical role in facilitating early identification, treatment, and support for affected individuals and their families. Nurses are often the first point of contact for patients and families seeking healthcare services, making it essential for nurses to be knowledgeable about these conditions and their associated diagnostic and treatment options (National Institutes of Health, 2021). Furthermore, nurses can provide valuable education and support to patients and families, helping them understand the condition and navigate the healthcare system.
