Genetics is the study of the chemistry of cells, tissues and organs associated with heredity. Clinical biochemical genetics involves the biochemical analysis of chromosomes as they relate to inherited tendencies. A clinical biochemical geneticist performs and interprets tests done for genetic purposes, such as diagnosing a genetic disease or disease risk. The geneticist can analyze biochemical laboratory tests to determine the diagnosis and management of genetic diseases and inherited disorders.
