Course Description

Credit Units: 2
Lecturer: Dr. IKWUKA A.O. (MD, Sp. Cert., PhD Medicine) Email Id: aloysiussweet@yahoo.com, College of Health Sciences, Department of Pharmacy & Pharmaceutical Sciences.

Course description:

This course explores the principles of human genetics and its medical applications. Other topics will include population genetics, genetic testing, clinical applications of genetics and new genetic discoveries for disease treatment. Students will also engage in discussion of current primary research literature in the field of medical genetics.

Learning Objectives:  With this course, students should be able to:

 Explain basic genetics, Mendelian inheritance, dominant and recessive inheritance.
 Understand some characteristics of the human DNA replication, transcription and
translation.
 Understand the structure of gene, the genetic code, chromosome, oogenesis,
spermatogenesis, mutation, polymorphism.
 Explain structural chromosomal aberrations: deletions, duplications, translocations,reciprocal translocations and inversions.
 Explain numerical chromosomal aberrations: euploidy, aneuploidy; and chromosomal aberrations: trisomy 13, trisomy 18, trisomy 21, Turner syndrome, Klinefelter syndrome.
 Explain autosomal dominant inheritance and autosomal recessive inheritance, genes and tumours, genes and drugs, X-linked inheritance, X-linked dominant (XD) inheritance, X-linked recessive (XR) inheritance, Y-linked (holandric) inheritance, enzymopathies, haemoglobinopathies.

Learning Outcomes:
Upon completion of this course, students should be able to:

 Explain the basic principles of human genetics and its medical applications.
 Describe the underlying molecular mechanisms, diagnosis, treatment and management of several hereditary disorders.
 Describe and explain the modes of genetic testing and explore ethical issues surrounding it.
 Discuss current trends in gene therapy, personalised medicine and predictive medicine, and the issues surrounding these.
 Analyse current scientific data and/or family histories and make appropriate diagnosticconclusions.
