1. Catalog Entry
BIOL 641
Genetics and Genomics for the Health Care Professional
Credit hours (3)
Prerequisites: BIOL 105 or BIOL 231 or permission from the instructor
This online course will provide a basic knowledge of genetic terms and concepts and an understanding of genomics that can provide health care professionals with a foundation that will enable them to provide competent, personalized healthcare. In this course the student will learn the basic genetic structures and functions, explain cellular and genetic changes, discuss genetic inheritance and describe chromosomal variations. Students will investigate resources available to healthcare providers for the application of genetics and genomics to patient care.

3. Detailed Description of Conduct of Course
This course will be offered only online. The course will be facilitated using approaches
appropriate to online delivery which may include but are not limited to recorded lectures,
faculty and student led seminar discussions, guest speakers, case studies, reading
assignments, written projects, problem sets and other strategies as appropriate. Because
the course is online, audio or video presentations/lectures, discussion boards, chat
rooms and other instructional technology strategies may be used.
4. Goals and Objectives of the Course
Upon successful completion of the course, the student will have the knowledge and
skills to:
1) Distinguish between genetics and genomics and describe the role of each for
informing health care decisions,
2) Draw pedigrees and assess recurrence risks based on family histories.
3) Calculate allele and genotype frequencies from population data and explain
differences in genetic disease prevalence
and probabilities among populations (“races”).
4) Identify various types of DNA mutation and predict phenotypic effects.
5) Describe the diversity of genetic tests available, the predictive value of
these tests and their appropriateness for
various populations.
6) Explain the role of genetic variation in personal response to pharmaceutical
agents.
7) Identify genetic aspects of cancer and considerations for cancer treatments.
8) Locate patient centered resources for genetic information.
5. Assessment Measures
May include but are not limited to: case studies, exams, quizzes, problem sets, simulations, student presentations and written projects.
