Medical genetics involves the study of chromosomal DNA abnormalities that cause genetic diseases, such as mutations or misdistribution of chromosomes. DNA sequences vary among individuals, accounting for our individuality in appearance, personal biochemistry, resistance to disease, and response to medication. Deleterious mutations are more serious than these individual variations and result in the appearance of disease symptoms in affected family members. We will review the patterns of genetic inheritance, recombinant DNA techniques, and the use of molecular genetics to predict whether or not individuals or their children may inherit a genetic disease.
