Case Study on AIIMS-SYLLABUS Biology syllabus Heredity

Genetic Disorder in a Family

Introduction: In this case study, we will explore a real-life scenario involving a genetic disorder within a family. This case study aligns with the heredity section of the AIIMS (All India Institute of Medical Sciences) Biology syllabus.

Background: The Patel family has a history of a rare genetic disorder known as Huntington’s disease (HD). Mr. and Mrs. Patel are concerned about the risk of passing on the disease to their children and seek genetic counseling.

Case Description: Mr. and Mrs. Patel, both in their mid-40s, have two children: Aryan, a 20-year-old son, and Riya, an 18-year-old daughter. Mr. Patel’s father had HD, and he himself started showing symptoms of the disease a few years ago. HD is an autosomal dominant genetic disorder caused by a mutation in the huntingtin gene (HTT) on chromosome 4.

Medical History: Mr. Patel’s father developed HD in his late 40s and passed away due to complications associated with the disease. Now, Mr. Patel is experiencing progressive motor and cognitive impairments, characteristic of HD. Genetic testing confirmed that Mr. Patel carries the mutated HTT gene.

Objective: The objective of this case study is to determine the risk of HD inheritance in Aryan and Riya and provide appropriate genetic counseling to the Patel family.

Genetic Counseling Process:

  1. Collect Family History:
    • Gather detailed information about the family history of HD, including affected individuals and their ages of onset.
    • Assess the inheritance pattern (autosomal dominant) and the likelihood of transmitting the disease to future generations.
  2. Risk Assessment:
    • Determine the probability of Aryan and Riya inheriting the HD mutation.
    • Explain the principles of autosomal dominant inheritance and the 50% risk of inheritance from an affected parent.
  3. Genetic Testing:
    • Discuss the option of genetic testing to confirm the presence of the HD mutation in Aryan and Riya.
    • Explain the benefits, limitations, and potential psychological impact of genetic testing.
  4. Psychological Support:
    • Provide emotional support to the Patel family, given the challenging nature of HD and its impact on family dynamics.
    • Address concerns, fears, and uncertainties associated with the disease.
  5. Reproductive Options:
    • Discuss reproductive options such as prenatal testing, preimplantation genetic diagnosis (PGD), and adoption.
    • Explain the pros and cons of each option, considering the family’s individual circumstances and preferences.

Conclusion: In this case study, the Patel family sought genetic counseling due to the risk of HD inheritance. The genetic counselor assessed the family history, explained the inheritance pattern, discussed the option of genetic testing, and provided psychological support. The counselor also addressed reproductive options to help the Patel family make informed decisions.

This case study highlights the importance of understanding the principles of heredity, particularly in the context of genetic disorders. It emphasizes the role of genetic counseling in guiding families through the complexities of inherited diseases, enabling them to make well-informed decisions regarding their health and family planning.
