Directions:

For this assignment (Conclusion of the “Case Study”), include Parts 1, 2, and 3 of the “Case Study” in one document, combined with additional genetics information learned from the assigned readings from all course topics. Make sure you have incorporated any faculty feedback received from previous reports. Do not copy/paste entire papers from Parts 1, 2 and 3. Create a document including only the following areas from previous case reports:

1. Describe the disease, its prevalence, its incidence, and general knowledge of the disease.

Conclusion of the Case Study

Huntington’s disease (HD) is a form of genetic brain condition that is extremely rare and progressive. It is defined by the gradual degeneration of nerve cells in the brain, which ultimately leads to emotional problems, cognitive loss, and movement that is not under the person’s control. HD is a genetic disorder passed on as an autosomal dominant trait during conception. The purpose of this paper is to conclude the previous three assignments on HD and discuss ethical considerations in HD, how genetics can improve care and health outcomes, and patient education plan for HD.

Parts 1-3

Huntington’s disease

HD is a movement disorder that results in neurologic and behavioral symptoms that usually become apparent from 30 to 50 years and worsen in the next one to two decades of a patient’s life. It causes chorea, neuropsychiatric symptoms, and dementia during middle age, and most patients eventually require institutionalization. It is estimated that 30,000 people in the United States (US) have HD, and another 20,000 to 50,000 are presumed to carry the gene (McColgan & Tabrizi, 2018). Males and females are equally affected at a time in their lives when they are highly productive. Studies reveal that children born to parents with HD have a one in two chance of having the disorder and can pass it on to their children. This risk increases to one in three if both parents have the disease.

Laboratory Testing

Lab testing for HD includes genetic testing for the disease using blood samples. Polymerase chain reaction (PCR) testing and fragment sizing are also performed on the cytosine-adenine-guanine (CAG) trinucleotide repeat region of the HTT gene to identify or rule out HD (Kim et al., 2020). These tests are conducted on individuals with a family history of HD, regardless of whether or not they have HD symptoms. In most cases, the findings of the lab tests are coupled with those of other neurological examinations.

1. Discuss the laboratory testing that can be done.
2. Describe if chromosomal analysis is/was indicated and detail the chromosomal change that caused the disease if it is a chromosomal disorder.
3. Describe the disorder in terms of its origin as either a single gene inheritance, or as a complex inheritance and considerations for practice and patient education.
4. Describe the gene mutation of the disease, as well as whether it is acquired or inherited, and how the mutation occurs.
5. Examine how genetics can influence policy issues.
6. Discuss any nutritional influences for this disease.
7. Process of nutritional assessment and counseling as it relates to health, prevention, screening, diagnostics, prognostics, selection of treatment, and monitoring of treatment effectiveness.

In addition, your case study must include the following:

Huntington’s Disease

Huntington’s disease (HD) is a persistent, neurodegenerative brain disorder with an estimated prevalence of 5 to 10 cases per 100,000 individuals (Ohlmeier et al., 2019). Globally, approximately 189,700 individuals are affected by this condition. Onset typically occurs between the ages of 30 and 50, although it can manifest at a younger age. HD profoundly impacts various aspects of a person’s life, including movement, behavior, cognition, understanding, learning, memory, and personality. A hallmark symptom of HD is chorea, characterized by uncontrollable, dance-like movements. Speech and walking difficulties are also prevalent, and additional symptoms encompass memory loss, poor concentration, task-execution challenges, impulse control issues, depression, lack of interest, sleep disturbances, sexual problems, difficulty swallowing, and an increased susceptibility to falls.

Laboratory Testing

Direct genetic tests constitute the most effective diagnostic approach for HD (NINDS, 2020). This method involves counting the number of CAG repeats in the HD genes, determined through DNA extracted from blood samples. Allele sizes ranging from 36 to 39, termed reduced penetrance HD-causing alleles, indicate a risk of developing HD without necessarily exhibiting symptoms (NINDS, 2020). In contrast, an allele size of 40 or more repeats is associated with the actual manifestation of HD.

Chromosomal Analysis

HD is an autosomal-dominant inherited disorder resulting from abnormal DNA replication (Roos, Wiklund & Laurell, 2017). The abnormality involves the repetition of Cytosine-Adenine-Guanine (CAG) in the DNA strand, occurring 36 or more times on the short arm of the chromosome for individuals possessing the Huntington gene. The condition is intricately linked to the multiple repeats of CAG in the chromosome of affected individuals.

Origin of Huntington’s Disease

Huntington’s disease (HD) is an autosomal dominant inherited disorder, requiring the inheritance of an abnormal gene from only one parent. The development of HD is closely linked to the HTT protein, a major determinant in its manifestation (Rodríguez-Quiroga et al., 2013). Molecular studies involving other conditions such as SCA (Spinocerebellar Ataxia) types 1, 2, 3, 6, 8, 17, and dentatorubropallidolusyian atrophy (DRPLA) have revealed the expansion of HD-like genes (HDL2) in carriers’ alleles, laying the groundwork for diagnostic advancements.

How Genetics Can Influence Policy Issues

The advancements in genetics necessitate consideration of healthcare policy issues, including genetic privacy, gene patenting, education, and the regulation and standardization of genetic tests. Challenges arise from the lack of testing regulation and assessment, leading to the realization that not all genetic tests are conducive to clinical assessment (Glasner & Rothman, 2017). Consequently, policy interventions should strengthen legislation in these areas, ensuring responsible and ethical genetic practices.

Genetics underscores the importance of public engagement in discussions concerning genetic tests, their use, and implications. Issues such as federal financing for genetic studies and the involvement of clinicians in direct-to-consumer genetic testing require public input to shape policies (Glasner & Rothman, 2017). Thus, public opinion plays a crucial role in influencing the adoption of policies that safeguard the interests of diverse stakeholders in society.

Nutritional Influences for Huntington’s Disease

HD is associated with the Huntington gene (HTT), characterized by expanded CAG repeats. This gene, found in the liver, is linked to deficiencies in the urea cycle. Dietary modification can regulate the activity of argininosuccinase acid lyase and argininosuccinic acid synthase enzymes, both integral to the urea cycle (Chen et al., 2015). For example, restricting dietary proteins has demonstrated normalization of blood citrulline and ammonia levels in HD. This leads to minimal aggregation of HTT genes in the liver, increased rotarod activity, and elevated striatal brain-derived neurotrophic factor (Chen et al., 2015). Consequently, these changes mitigate deficiencies in the urea cycle, thereby reducing the severity of the disease.

Process of Nutritional Assessment and Counseling

In patients with Huntington’s disease (HD), marked weight loss is a common concern, necessitating nutritional assessment by a dietitian. Factors contributing to weight loss in HD include mood fluctuations, behavioral changes, and difficulties in swallowing (Domino et al., 2019). The nutritional assessment process should encompass various aspects, including an evaluation of the patient’s eating habits and patterns, as the disease can significantly impact these. Additionally, the severity of dysphagia should be assessed, utilizing tools like the Swallowing Disturbance Questionnaire (Domino et al., 2019). Evaluation for signs of food aspiration during the consumption of liquid foods is also essential. Nutritional counseling for patients experiencing weight loss may involve recommendations for high-calorie and protein supplements.

Ethical Considerations for Huntington’s Disease

The practice of genetic counseling for Huntington’s disease (HD) should adhere to ethical principles such as autonomy, beneficence, nonmaleficence, and justice. Health professionals must navigate the complexities of these principles, sometimes making decisions that may be perceived as paternalistic and potentially overriding respect for autonomy. For example, conditional access to the HD predictive program may be viewed as a paternalistic approach. These ethical principles are grounded in the ethics of care, emphasizing an understanding of an individual’s circumstances, needs, and feelings to ensure a comprehensive and empathetic approach to genetic counseling for HD.

Comparative justice should be considered in genetic counseling, especially when a person’s needs have to be weighed against those of another. The counselor should consider the possible consequences for the persons involved and analyze who would benefit more and who would be harmed more. The counselor has a duty of preserving the confidentiality of the client’s genetic information from a third party, even if it is a close relative. Information on genetic test results in HD can cause discrimination, stigmatization, and insult to the client’s psychological well-being. Genetic testing often raises questions about intrafamilial relationships, disclosure, confidentiality, and paternalism.

The principle of beneficence in genetic counseling and testing in HD should be considered. The counselor should inform clients on the benefits of genetic testing, which include: eliminating parents’ worries, facilitating planning and preparing for the future, providing early treatment, and maintaining vigilance in healthcare. Furthermore, the counselor should uphold the principle of nonmaleficence by considering the potential harms of genetic testing in HD. Potential harms that should be considered include: disrupting the parent-child relationship, lowering a child’s self-esteem, triggering anxiety about the onset of symptoms, taking away a child’s right to decide, and providing no direct benefit to the child.
