Principles of Medical Genetics

There are still some who harbor the misconception that genetics deals only with the rare and exotic, or that those involved in medical genetics devote themselves entirely to counseling persons having or at risk for genetic disorders for which nothing else can be done. Yet a glance at almost any of the current clinical or basic science journals generally provides ample evidence of the exceedingly broad relevance of genetics. Within the spectrum of genetic disorders, many can be treated effectively, particularly the birth defects involving malformations amenable to surgical correction, and treatment of others can prevent the most serious consequences.
